Sinister ATV/mc Accessories:

Again it's been a big month for Sinister - finally our new retail outlet and workshops have opened and things couldn't have been busier.

It has been an amazing first 8 months and slowly but surely we have been bringing many old customers and plenty of new faces through the door - all it takes are the best quality of products around and the unmatched service we provide.

Due to customer demand we were forced to move forward the opening of our own workshops and have been lucky enough to get in touch with a highly recommended service technician and fantastic electrician who have been with us from the opening day.

We now enter the market with the promise of quick and excellent road legalling, superb race preparation, service and repair - these new lines of business are now the way forward for Sinister ATV/mc Accessories.

With over 1000 sq feet of workshops, two dedicated service bays complete with ATV lifts and individual tooling for each bay, we are happy to help with all two and four wheelers.

Our Qualified Service Technician will be on hand to help with any service or repair to your ATV. Sinister ATV/mc Accessories will be able to help with all your aftermarket performance products fitting, race preparation and road legalling.

We hope to continue to offer excellent customer service while placing your needs above all else and to continue to expand our aftermarket performance accessories range to include more amazing products from Europe and America.

We have a massive selection of service parts for two wheel and four - aftermarket and oem that are always in stock so no problems replacing bearings and seals, pads, chains, sprockets, grips, wheels and tyres etc on a Friday afternoon.

We try to hold as much product in stock as we know you need things now and that next day delivery is not always good enough (if it ever turns up, mmmh). We currently hold a massive selection of products (rising due to the size of our new retail outlet) with aftermarket performance accessories from most of the major brands making us one of the most complete retail outlets on the UK market today.
