Everything is new in the original packaging. PRICES AND LISTINGS ARE SUBJECT TO CHANGE AT ANY TIME WITHOUT NOTICE. DO YOU MAKE A LIVING WORKING ON BIKES? ARE YOU A SHOP OR DEALER. At BPRATV we sell parts from the best names in the industry.

Unless otherwise stated, we will put the quality of the parts we sell up against any other companies' in the industry. Also, we stock the same parts from different manufacturers so that when back orders occur like they have been for the last year we have an alternate part to send that is the same quality. This would be the ONLY reason your order might be slightly different when it arrives.

If you want a certain brand part just ask (if part is back ordered this may cause a delay on your order). 99% of problems can be easily solved without returning the entire order. Once items have been modified, installed, or used in any way they are not eligible for return. Everything we sell has been tested hundreds if not thousands of times and when installed and tuned correctly they work over 99% of the time. Part failures happen, but it is rare that it is not due to being installed incorrectly.

This product is NOT DIY. Over 99% of people in the world are not qualified to build an engine, and it is the responsibility of the person assembling and tuning the engine to make sure everything works correctly. It requires special tools and has to be done 100% correct.

Many parts must be measured down to. We ALWAYS STRONGLY recommend parts be installed by a qualified, experienced mechanic. If it can not be fixed we will supply you with a new one.

Also, we want information from customers when their experience is less than desirable so we know what areas need improvement the most. Please work with us and we will ALWAYS work with you.
