i recently got a 2005 gsxr 600 and it has less then 100 miles on it i live vermont andd cant drive a bike in the winter i want put a rear end from a sport quad on it but i im not sure what to use the most avaliable thing i have is a yfz 450 that needs a crank rebuild and probally wont be done any time soon so i could use that still probally wouldnt be the best for winter but what the hell it would be fast ne one have suggestions or what do uthink of the idea

 

well youre much better off just taking the motor and putting it in the quad. i really dont see the point of a sportbike with a quad rear.
