Terminal Protection -Over time, battery terminals can corrode, causing poor contact with your connections. This can lead to an eventual dead battery and a long walk home if it isn't treated properly. A mixture of baking soda and water neutralizes the corrosion-causing acid ensuring a good contact between the battery cable and post. Don't stop with your quad as this tip also works on your car, truck and lawn mower
Carburetion Collaboration -
With spring in full effect, the temperatures will be rising soon. This means the air is becoming less dense and your quad may need to be rejetted. With the cooler air temperatures of winter, the machine requires additional fuel, which means a larger main jet. The opposite is true for warmer temperatures. The air is thin and less fuel is required to obtain the perfect air-fuel mixture.
Revive Your Worn Pegs -
Unless you're using a pair of stainless aftermarket footpegs, you will notice the sharp edges wear down and will dull over time. There's a simple solution to bring the pegs back to life and keep your boots firmly planted with no slipping. All you need is a metal file and a few minutes of manual labor to hone the teeth of those worn pegs. This can be repeated a couple of times before the purchase of a new set of pegs becomes necessary.
Repack For Improved Power -
You may like that loud rumble coming from your exhaust, but a poorly packed silencer does in fact rob horsepower. A properly packed silencer will keep the noise to a minimum and allow the exhaust to exit faster with less turbulence. As more air flows through your engine the potential for more horsepower increases. Another tip to remember is wrapping safety wire around the packing to keep it securely placed around the exhaust baffle during reinstallation.
Often Overlooked -
While performing routine maintenance on your quad, don't forget to remove and lubricate your swingarm pivot bolt regularly. Applying a generous amount of grease to the needle bearings in which the bolt rests can add many rides to the life of the bearings and bolt. It's much easier and cheaper-bearings and bolt can cost in excess of $50-to grease it regularly than replacing it. Also, if it isn't greased periodically, it can be difficult to remove once rust begins to build up on it.
Tower's Tape Tip -
After installing an axle, it's a good idea to wrap the locking axle nuts with tape. This will keep the nut snugly secured together and prevent the axle from coming loose. This often goes unnoticed until it's too late and damage has already been done. Learning this lesson the hard way can cost hundreds of dollars, so better safe than sorry. Tape it up!
Gusset Before You Paint -
There's nothing like the glistening sight of a freshly powdercoated frame. Before you pick out a color, you may want to add some additional reinforcement to the weak points of your frame. Do it yourself or contact a fabricator with knowledge of your specific model to eliminate the guesswork. The experts at Lone Star (www.lsracing.com) have kits precut and ready to weld for most applications.
Braking News -
Water and grime are the No. 1 killers of drum brakes. When replacing the pads on drum brakes, apply a thin film of waterproof grease to the dust seal. This will add an additional layer of protection against the brake-eating elements. Keeping the drums clean and dry will not only guarantee a safe stop, it will also save some dough.
More Zip-Tie Tips - Zip-ties can be used literally for hundreds or maybe thousands of small fixes for your ATV. So it's obviously useful to keep a few around at all times when you're out riding. If you're out on the trail and you lose a bolt from your plastic, whip out a trusty ole zip-tie and secure your plastic until you can replace the bolt. It's saved us on countless occasions and it could save your ride as well.
The condition of your air filter directly affects the performance of your ATV. The dirtier the filter, the more it robs horsepower from your motor. Running a dirty filter also greatly increases the risk of sucking dirt and debris into your motor's internals which can cause a number of problems in your fuel-delivery system and greatly increase the wear and tear on your piston rings, cylinder and valves.
Once again, this eats away at even more horsepower in the long run. The best practice is to clean your filter often and well. How often? We suggest cleaning your filter after every weekend of riding, and even swapping out a clean filter for every day of riding if the conditions are extremely dusty. If you wait for your filter to look like a dirt clod, it'll be too late. So how do you clean it well? Follow these steps and we'll get your air cleaner well, cleaner.

Summary
Cleaning the air filter is the most important maintenance job you can perform on your ATV, with a few steps, we'll try to make it the easiest job, too.
Tip
It's a good idea to have at least two to three spare filters for your ATV, that way you can easily swap out a dirty one when you're out for the weekend, and it's easier and more efficient to clean a batch of filters all at once.
1 Remove the air filter from your ATV. Make sure to cover the intake with a rubber glove, plastic bag or clean shop rag to keep foreign particles out while you're cleaning.
2 If your filter has an inner support or frame, remove it before cleaning. Be careful not to tear the filter when extracting the frame.
3 If you've got some heavy dirt buildup, lightly brush it off with a soft-bristled brush. You want to use a flicking motion and be extra careful not to grind any dirt into the filter.
4 Spray down the dirty filter with cleaner to begin breaking down the oil and grime. We suggest using Maxima air filter cleaner, but you can also use a degreaser like 409. If the old filter oil is really stubborn, a mild parts cleaning solvent will help break it down. Let the cleaner soak for about 5-10 minutes.
5 Using a faucet or garden hose (hot water works best), rinse out the heavy dirt and oil. Make sure you only rinse from the inside out; rinsing the other way can lodge grit farther into your filter. Rinse until clear water comes out of the filter.
6 Fill up a bucket with hot soapy water; we suggest using either a laundry detergent or dishwashing soap. Submerge your filter in the bucket and let it sit for about 10-15 minutes.
7 For K&N or gauze filters: Dunk the filter in the bucket a dozen times to help clean out the grit and oil. If needed, use the soft-bristled brush again to flick out the really stubborn dirt. For foam filters: Wash out the filter by hand and be sure not to tear it as you're working it over.
8 Using the same method as before, rinse your filter again. Be sure to flush out all the soap from your filter.
9 Take a minute to look over your filter. If there's old oil or traces of dirt left in the filter, you'll need to repeat the washing process. It's very important that you get out as much of the oil as possible. If you let it go, the old oil will become even harder to wash out in the future and will start to restrict the airflow of your filter. K&N filters should be light gray (no pink) and foam filters should be back to their original color.
10 Dry your filter. Foam filters should be compressed to remove excess water. Don't wring out a foam filter, you'll risk tearing it. Both types of filters should be set in a clean, well-ventilated area to dry for at least 24 hours. The drying process is very important because any moisture left in the filter will keep the new oil from correctly absorbing into the filter.
11 Oil your filter. K&N or gauze filter: These types of filters should be oiled with K&N (or comparable) aerosol oil. Lightly coat the filter up and down each pleat, holding the can about six inches away. After one pass, go back and touch up any spots you may have missed. Let the filter sit for about one hour then apply a second coat of oil. After the second coat, your filter should be solid red, if there are any light spots, reapply oil as needed. Make sure to wipe any excess oil and overspray.
Foam filter: Put your filter in a gallon-size Ziploc bag and pour in a generous amount of oil. We suggest using Maxima FFT (Foam Filter Treatment). Seal up the bag and start massaging the oil into the filter. Gently work the filter until you have an even shade; dark spots mean you've got too much oil on that area, light spots mean not enough. When you have an even coat, remove the filter from the bag, wipe off any excess and let it sit overnight before reinstalling. Leftover oil can be poured back into the bottle to reuse.
12 Clean out your airbox. Any dirt left in the airbox will just be sucked up in your filter the minute you start your ATV. Wiping it out with a damp rag should do the trick; just make sure the intake is covered to keep any dirt from falling in. If it's really dirty, it may be easier to take the airbox off the machine and wash it out with soap and water.
13 Reinstall your filter. Clamp-on filter: Make sure both the mounting flange on your filter and ATV are clean before installation. Don't apply grease to clamp-on style filters. Also, don't overtighten the clamp, especially if your ATV has a plastic flange on the airbox. Overtightening can warp or break the flange, causing a catastrophic air leak. Press-on filters: Make sure the seals on the filter and the airbox are clean and apply a moderate coat of waterproof grease. This is very important and helps to keep dirt from seeping through the seal.
Tip Always double-check your filter installation. Make sure your filter is on straight and clamped down securely.
14 Put your extra filters in Ziploc bags so they stay clean and are easily accessible. To protect your filters from damage, we suggest keeping the bagged filters in large coffee cans or a plastic storage container.
The test for methanol fuel has been extensive over the last five years and a lot has been learned how to set up engines and carburetors for most ATV applications. The following is a list of tips that every methanol fuel user should be aware of.
Preliminary Facts Regarding Methanol
Methanol fuel is generally harder to set up for than petrol, therefore Sinister recommends its use for experienced tuners only. If you are not proficient in jetting carburetors and evaluating engine performance then it is best to gain these experiences with petrol first.
Methanol fuel is recommended for short duration racing only such as drag racing or short sprint racing, you will consume twice the amount of alcohol fuel for any given horsepower output when compared to petrol, so the range of your fuel tank is basically cut in half.
Because methanol is "hygroscopic" meaning it absorbs water, it requires special handling procedures. The number one piece of advise is to buy only as much fuel as you will use in a week, and buy the fuel from a reputable vendor who stores the fuel in sealed metal drums.
It is preferable to store methanol in a sealed metal container. Plastic is OK for short term storage only, but put the container on wood, not on the ground. Be sure to keep your container sealed at all times.
In addition to attracting water, methanol is corrosive to metals, gaskets and seals. In four stroke engines it is recommended that you use a "top lube" or methanol fuel treatment in order to combat corrosion. Many motorsports oil manufacturers make products specifically for treating methanol fuel systems.
For two stroke applications Sinister recommends a pre-mixed of 28:1, this will combat corrosion and sufficiently lubricate the engine. Check with the oil manufacturer before mixing your favorite oil with alcohol.
Methanol must be drained from the fuel system at the end of the day every day. This is especially important in the coastal climates. Because fuel tanks and carburetors are ventilated to the atmosphere the methanol inside will absorb water and corrode costly fuel system components.
Once the methanol has been drained from the entire fuel system you will have to put petrol into the carburetors and run the engine. We use a radiator overflow bottle filled with pre-mix, attach a hose from the bottom of the bottle to the fuel fittings on the carbs. Start the engine and run it for two or three minutes, leave the petrol in the fuel system until the next ride.
Engine and Fuel System Set Up
Because alcohol fuels burn so much cooler and slower than gasoline Sinister recommends that you increase the compression of the engine to maximize performance, there will be little or no advantage to running methanol on a stock compression ratio. We suggest first checking your cranking compression and then consulting your engine builder before running methanol, some engines will tolerate less compression than others.
Advance the ignition timing. Your results may vary depending upon compression ratio and the sophistication of the ignition system. Proceed carefully and document the timing change by measurement, either by degrees of crank rotation or by millimeters before top dead center.
Minimize flow restrictions between the fuel tank and the carburetors. Remove the petcock from the fuel tank and cut off the filter screen and the reserve stand pipe. Remove any in-line fuel filters or petcocks, use as large a fuel line as you can fit over the fittings on the carbs and petcock.
Check the operation of the slide, make sure that it opens all the way to clear the bore of the carburetor, this is particularly important with modified or bored carbs.
Put taller gearing on the machine. In our experience a methanol equipped ATV will pull a one tooth larger countershaft sprocket. If you run a 13T on petrol try a 14T on alcohol.
Procedures For Tuning Methanol
Even if you are an experienced tuner, you will want to read up on your particular carburetor design before you proceed with methanol testing. Some of the best information is available in the manufacturers shop manual for your particular machine, most manuals have excellent carburetor sections, and all of the procedures for tuning petrol will apply for methanol, just the jet sizes will be different. For aftermarket carburetors we suggest getting the Sudco/ Mikuni tuning manual, this book has some good general information that applies to Keihin as well as Mikuni products.
When you initially set up the carburetor for methanol err on the side of rich. Alcohol fuels generally have a wider air/fuel ratio tolerance for good power, methanol will make excellent power from a correct air/fuel ratio up to a rich condition, there is no need to "lean her out" in search of power as you would with petrol.
Methanol fuels are less tolerant of a lean air/fuel ratio than petrol and will detonate violently. Fortunately methanol detonation or pinging is quite audible, so if you hear any "rattle" you must stop immediately and richen the carburetor settings.
Tune from the bottom up. Dial in the slow circuit and air screw first, then the needle and clip position,then the main jet, and the power jet last. Don’t change the main jet if you have a problem at part throttle/ low speed.
Some words about the power jet. The power jet is essentially another fuel circuit in addition to the slow and main circuits, the power jet is throttle position sensitive and generally only comes in from 3/4 throttle and up. Many power jets have a screw type adjuster on them so you can vary the amount of fuel they deliver, turn the screw out from seated in order to increase the fuel fuel flow. The power jet will allow you to keep the slow and mid throttle settings clean/ correct and still allow enough fuel flow for wide open high rpm power.
The useful range of the power jet adjuster found on a carb is 1/4 to 3 turns out from seated.
When you test the methanol jetting be sure to make several passes before you settle on a particular main jet size and power jet setting, it will take a few passes for the engine to come up to operating temperature, if it doesn’t detonate on the first run it may do so on the third or fourth so proceed methodically.
The main jets supplied in a alcohol carburetor are sized according to the number drill index, therefore the smaller the number scribed on the jet, the larger the hole will be.
If you are running into a lean condition at wide open throttle (WOT) and you are getting no results by enlarging the main jet, you have reached the fuel flow limit of the needle and nozzle combination. (i.e.) The clearance between the needle and nozzle at WOT is too small to feed the larger main jets. The next step is to sand the last 14mm(9/16") of the needle to a smaller diameter, this will increase the area of the needle/nozzle combo and allow the potential for more fuel flow through the main circuit. This should put the large main jets you tried earlier back into the useful range. Put the needle in a hand drill, take a piece of sand paper and carefully sand the last 14mm of the needle to the same diameter as the very end of the needle just before the final bevel.

Stopping your ATV is paramount over going fast, or you will only go fast once, which is why a properly functioning brake system is important. Routine inspection and maintenance on your ATV’s brake system is critical to riding safety, and your brakes should be inspected before each ride because over time your brake pads will need to be replaced. Depending on your riding conditions, brake pads could last for years, or need to be replaced monthly, which is why routine inspection is so important.
Beyond the brake pads, proper brake fluid level is also extremely important, and should be checked as well before every ride. Most sport ATVs are equipped with a front brake master cylinder mounted on the handlebars along with a rear brake master cylinder, which is usually mounted on the side of the rear sub-frame. The front master cylinder has a sight window for checking your brake fluid for easy inspection. To properly check the fluid, the master cylinder must be level, so this may require re-adjusting the master cylinder to determine the actual fluid level.
ATV Front Brake Master Cylinder with sight window for checking the brake fluid and the top can be easily removed with just 2 screws to add fluid or inspect the brake fluid
The Rear ATV Brake Master Cylinder attaches to the brake pedal and the fluid reservoir is mounted above it normally behind or the fenders or tucked along the sub-frame
The rear master cylinder is normally a clear small cylinder, which is similar in size to a small pill bottle. It is typically clear with fill levels indicated on the side of the cylinder, but again the reservoir must be level to properly determine the fluid level.
The fluid level may be fine, but the color is also important. The brake fluid is typically a yellowish / clear fluid, but if it turns brown or has a burnt smell, the brake fluid was boiled at one point and will not be as effective in the future. It will be prone to breaking down and boiling, which prevents the brake fluid from engaging the brake pads to stop your ATV. If you are an aggressive rider and have ever temporarily lost your brakes during a ride due to boiling your brake fluid, I highly recommend switching to a high grade synthetic brake fluid because they have higher boiling points than conventional brake fluid. It is very important that you drain out all the old brake fluid before switching to a new brand or synthetic because the different fluids can interact with each other and cause even more issues.
Finally, we have the calipers, pads, and rotors. These items work together to bring your ATV to a stop, so they all need to be inspected routinely as well. The rotors come in various shapes and sizes, but a bent rotor will not allow your brakes to work because they will press your pad back into the caliper and prevent maximum stopping power. A quick spin of the wheel while watching your brake pads or caliper for movement will quickly let you know if your rotor is bent. If you find your rotor is bent, it should be replaced before your next ride.
When inspecting your rotor, you will also be able to tell if your brake pads need to be replaced as well, and I suggest keeping a spare set of brake pads on the shelf for the front and rear because they will eventually need to be replaced, and it is better to have them ready for installation when the day arrives.
Rear ATV brake rotors are prone to damage from debris on the trails such as rocks and logs, so it is important to ride with a skidplate when riding in harsh conditions to help prevent bending a rotor
Besides, routine brake maintenance, over time, your actual brake caliper will need to be rebuilt or replaced, but considering the expense, it would be much more economical to just rebuild your calipers for many more years of use without the additional expense, so we have provided a step by step ATV brake caliper disassembly article for those do it yourself riders, which can save you even more money and gain a better understanding of your ATV’s braking system in the process.
In Review, here are the five major ATV brake system components and their functionality
Brake Master Cylinder - Holds the brake fluid and when operated by your brake lever / pedal pumps pressurized brake fluid to the brake caliper to make it operate
Brake Lines - carries the brake fluid from the master cylinder to the brake caliper
Brake Caliper - Houses the pressurized brake fluid and when applied, forces a piston out of the caliper to contact the brake pad, which in turn forces the pads to squeeze the brake rotor.
Brake Rotor – This item is connected to your front hub or rear axle assembly (rear Brake Hub) and is what the brake pads contact when pressure is applied to the system via the brake lever(s)
Brake pads - These two pads are made of either sintered metal or organic compounds and are held in place by two sliders in the brake caliper housing and provide friction from the force of the system to stop your ATV.
All of these components work in harmony to bring your ATV to a stop, so routine maintenance of all these items are critical to proper ATV riding safety.
Shielded From The Elements
On a wet day it's a good idea to place foam into voids around the airbox. The foam will prevent excessive amounts of splashing water and debris from reaching the filter and stalling the machine. The last thing anyone wants is to end their day with a swamped quad.
Wheel Wise
If you're looking for added width or maybe even narrowing a machine to your style of riding, a new set of wheels may be the answer. Virtually every wheel brand offers multiple offsets to achieve the desired customer width. Check for available offsets before you make your next wheel purchase.
Reliable Thread Repair
I've seen numerous ways to incorrectly repair threads in frames and engine cases that have been damaged or stripped. There's a simple fix for this problem that doesn't require unsightly gobs of liquid metal or mismatched bolts. Installing a helicoil has a ranking of three on the difficulty scale and will allow use of the proper type and size fastener. Several types of these thread repair kits can be found in automotive part centers or at your local hardware store.
Bag It
Drilling extra holes in an airbox lid for added airflow is quite common. The problem arises during routine washing when water passes through these holes filling the airbox. To combat this minor issue, place a plastic bag over the airbox before installing the lid. This will keep water away from the air intake and ensure the filter remains dry.
Carpenter Tools Not Allowed
There comes a time when only a hammer will get the job done. A claw hammer typically used for framing isn't the best choice for mechanical applications. This is where a brass hammer comes into play. The soft brass carries the same impact without the added risk of further damaging delicate components.
Over Time
If you ever find yourself in need of performing some last-minute maintenance on your clutch before the waving of the flag, this tip is for you. Turning your ATV onto its side will keep the oil away from the clutch and allow a quick inspection or change of the plates without the necessary time needed to drain and refill the crankcase. It does prove to be a little more difficult working on the machine in this position, but when every second counts it may put you on the starting gate before it drops.
Perfect Match
It's only a matter of time before the paint on your frame, A-arms and swingarm begin to wear. As you already know, anywhere the bare metal becomes visible, rust will soon follow. Don't panic when this occurs, there's a way to keep your tubing looking new. Color-matched cycle paint is available from your local dealer for touch-up or a complete refinish.
Lock Down
When riding in the mud or wet conditions especially during subzero emperatures, vapor lock can occur when vent hoses become blocked. This creates a vacuum and restricts fuel flow bringing things to a screeching halt. By cutting the end of vent lines at a steep angle it becomes increasingly difficult for mud or ice to clog the tip of the hose. It's also a good idea to check the vent hoses for unwanted debris during routine inspections.
Many of today's sport quads have the crankcase breather tube running up into the airbox. In extreme racing situations, the breather tube can blow crankcase oil all over the air filter. To remedy this, many race mechanics run a longer tube up past the airbox and toward the back of the ATV by the grab bar. A tiny aftermarket filter is used to keep dirt from coming in as well as to keep the majority of the oil from coming out
Most powerful, stable, toughest sport ATV
Rotax® 650cc High Output engine puts out the most power and torque in its class
Incredibly capable sport-tuned suspensions with High Pressure Gas shocks with infinite pre-load adjustments
Reliability proven in the most grueling races
Available only as race-ready X-version
You don’t win the Baja 1000, Baja 500, San Felipe 250 in the same year unless you have a fast – really fast – engine. And you don’t win the Paris-Dakar rally unless you have a incredible durability. And you don’t accomplish these feats unless you ride a Bombardier* DS650 X ATV. And riders don’t have to be part of a top factory race team to get that type of performance, because the 2006 DS650 X delivers this level of performance and reliability right out of the box.
Consumers might not be taking their DS650 X out for a 1000 mile (1,600 km), all-out spin through some of the most unforgiving terrain on earth…but its racing pedigree ensures that busting through dunes or slicing through trails has never been so exciting.
Racing is about being fast, and the DS shines in that department with its Rotax 650cc single-cylinder mill. Liquid-cooling, four-valves, dual cams and dual sparkplugs all work together to deliver the most power and torque in the class. Plus, this engine has proven to be absolutely reliable in even the toughest conditions.
Tackling unforgiving terrain requires suspension performance and the DS650 X delivers in spades. Double A-arms in the front use High Pressure Gas [HPG] shocks to soak up the bumps and control the ride. An aluminum swing arm with a single Kayaba HPG remote-reservoir shock does the job in the rear. Travel up front is a full 12-inches [30.5cm] and 11-inches [27.9cm] in the back. To tailor the ATV’s performance for riding style, terrain and conditions, the front shocks have an infinite pre-load adjustment; the rear shock has adjustments for pre-load, compression and rebound.
Even the most punishing DS650 X owners will have no doubts about reliability, with a full compliment of heavy-duty components, such as 530 o-ring chain, tapered bearings, six-bolt sprocket carrier, and aluminum rear axle. Racing or riding at night? In addition to its dual lamp headlamp and auxiliary halogen lamps, the 290-Watt magneto can power even more.
The X-package features list proves this is a serious, race-ready ATV. There’s no need for another big-dollar shopping trip to get this baby ready for fun, as all these trick items – that’s more than $1,800 USD[$2,400 CDN] in value – are standard:

FEATURES
To finish off a disc brake bleeding session, top off the master cylinder with fluid and open the bleeder once you are confident that the bleeding is done. Then pry the brake pads back (open the caliper up) and pump the brake lever one more time, being sure to hold the lever in.
Now close the bleeder and pump the lever until it has a good, strong feel. This technique will pop out any bubbles that have lodged themselves behind the caliper pistons during the bleeding process.

Outlander 400 H.O. Key Features
Visco-Lok Front Differential – Progressively transfers power from a slipping front wheel to the gripping one – automatically with no buttons to push or levers to pull. Plus, there’s no wheel hop or driveline wind-up so the system is totally transparent to the driver and extremely easy to steer. Can lock up to 100% with no rev or speed limiter. Can-Am exclusive.
Trailing Torsional Independent (TTI) Rear Suspension – Trailing arm design provides more control and stability, especially in rough terrain, by eliminating scrub. Wheels move rearward as they move up and down producing a smoother ride than the competition, and does not steer from the rear. Plus, TTI has 75% fewer parts than competitive designs and significantly decreases tire wear
MacPherson strut front suspension – Compact design is lightweight, and provides precise handling and a plush ride.
Surrounding Spar Technology (SST) frame – Rather than the common tubular box, the SST frame is a single spar that is lightweight, yet strong. It contributes to the Outlander’s benchmark power-to-weight ratio and low centre of gravity. And the unique design enables the ATV to “ski” over obstacles.
Multi-function digital gauge – Gauge is easy to read with multiple functions, including:
Digital speedometer
Odometer
Trip meter
Gear position
Hour meter
Engine hour meter
4x4 indicator
Temperature/Engine lights

DS 450 EFI Key Features
Rotax® 4-TEC 450 EFI – This new engine is the most powerful in the class. The top-end of the DOHC single has DNA from the Rotax V990 which powers the Aprilia‡ RSV 1000 R sportbike while the crankcase, clutch and transmission are specifically designed for the rigors of offroad riding. Its free-flow design – with the largest piston bore, intake valves and throttle body of the segment – delivers awesome power and great potential for performance tuning. A sophisticated EFI system with superfast micro-controller optimizes performance at every rpm, compensating for both temperature and altitude; throttle response is instant.
ALTEC™ aluminum frame – Aerospace-grade aluminum in dualpyramidal design is exceptionally strong and lightweight. Unique aluminum lock-bolt fastening system eliminates the need for welds. Strength comes from computer-optimized design rather than heavier or added materials. The pyramidal structure has been proven on BRP’s Ski-Doo® REV™ and REV-XP™ snowmobiles.
R-type double A-arm front suspension – The new R-Type forged aluminum double A-arm front suspension delivers razor-sharp handling, remarkable bump absorption, and confident tracking. The radical design with inverted dual-piston caliper – on the inside of the disc – enables placement of the ball-joints and kingpin axis deep inside the wheel for reduced scrub and steering kickback, as well as self-correcting behavior under hard braking. All this in a lightweight package with less unsprung weight than competitive designs for a better ride and improved control.
KYB HPG piggyback shocks – Aluminum-bodied shocks with compression and rebound adjustment and threaded pre-load adjustment. Features 9.5-inches (24 cm) of travel in front, 10.2 inches (26 cm) in rear. Lightweight, capable and adjustable.
R-Type rear swing arm suspension – Lightweight design dramatically reduces unsprung weight for quick response, exceptional traction capability and less rider fatigue. Cast-aluminum swingarm with rising-rate linkage, hollow Chromoly 4140 rear axle, extended-reach aluminum hubs and aluminum chain sprocket.
Wilwood™ braking systems. Inverted dual-piston calipers – mounted inside front rotors – enable unique knuckle/spindle/A-arm design. Front and rear rotors’ wave shape is computer designed for exceptional cooling.
Performance wheels/tires – Specifically-designed ITP‡ Holeshot‡ SR tires to get maximum performance from the DS 450 EFI. The rims are lightweight, yet durable, because of aluminum construction with rolled bead.
Performance ergonomics – Designed to give the active sport rider room and the right leverage. Narrow body and seat with smooth transitional surfaces, wide foot pegs and deep heel guards.
Performance features – Detachable headlights, interchangeable front fenders

FEATURES
The Can Am DS450 has a built-in auxiliary fuel/timing map. This was put in place before the production units went on sale to provide the owners with the ability to make modifications to the engine without suffering from excessive leanness, which is a sure recipe for disaster. Whenever any modest performance mods are made, such as removing the air box lid, adding a freer breathing air filter set-up, or installing a performance exhaust system, this wire must be cut. Our dyno testing of the DS450 found that with the stock map, the engine went scary lean as soon as we bumped up the power output.
We used a very expensive custom controller we developed to allow us to modify the fuel and timing maps to stay in perfect tune with the enhanced engine output. We sent BRP a copy of our final map that was tuned for our free-air kit and full exhaust system. This added 6 horsepower and required significantly more fuel. When the production unit came out we found that the auxiliary map that was installed into the stock ECU was very close to what we had sent them.
Their version was slightly richer than ours and had slightly more ignition timing than ours, but for all intents and purposes the map was nearly identical. This bodes well for customers installing air and pipe kits as this saves the cost of an expensive aftermarket controller and the dyno testing it would take to dial it all in.
This is not a perfect world we live in and this map is no exception. While nearly perfect for most air kit/pipe combo, it is not perfect for applications that you will still want to use it for. As an example, if you only remove the air box lid you would be slightly leaner than optimum, but not lean enough for the richer map to be ideal. The solution would be to cut the wire and live with the slightly rich condition to assure the safe operation of your engine.
Add a free breathing air filter and adapter and you will find the fuel mixture much closer to ideal. Add the pipe and you will be right on the money. Add wild cams, porting, or mongo compression ratios and you might have moved out of the ballpark of the wire mod.
To be safe, a controller may be called for at this point, although we have sold a number of 14:1 pistons that seem to work well with just the wire mod.
Activating the auxiliary map:
First you must remove the plastic covering the fuel tank. You will find a large bundle of wires running from lower rear to upper front along the left side (see photo). In the area of your left knee (if you were sitting on the quad), you will notice a small loop of pink wire with a black trace coming out of the bundle.
That has been conveniently placed there so you can easily access it. Simply cut the wire, seal the ends, re-install the plastic and you are ready to go. Should you return the bike to stock at a later date, simply splice the cut back together and you will return to the original program.
In 2001, José Boisjoli, BRP President and CEO, set a challenge. “Give me a sport ATV with the lowest weight, lowest unsprung weight, most mass centralization and highest power, and you have yourself a project.” This no compromise approach forced Can-Am™ engineering teams to throw out convention, and rethink everything from the frame to the front and rear suspension systems.
The DS 450 offers the most power, lowest weight, most centralized mass, and lowest unsprung weight in its class. Plus, a fully-adjustable, sport-tuned suspension.
Six years later, the new DS 450™ EFI was born. The four objectives were met, and more than half a decade of relentless dedication and passion rewarded. Now, Can-Am has taken the DS 450 EFI a step further introducing the new X package.
