alright me and my friend came across a xr 600 for a trade we made, well the thing runs perfect and has some balls, but the bike is kinda getting old and little things keep going out on it, so has anyone put a 600 in a trike, if its not possible and its kinda off subject to trikes but has it been done to a quad, we are looking to make a ice racer out of it so the frame doesnt have to besuper strong for off road becuase it will be strickly on the ice, any ideas? thanks

put a 250r front end on it. Just press out the 250r stem thing abf press in the 250r one. Then use some trike rear end or quad rear end.. Simple./.

do you have to do any cutting or modding anything or is it just a matter of changing parts
