I just blew the tire on my stock 1978 CB750K so its time to get some new tires. Could anyone tell me what the biggest/best tire is to put on the stock rear rim and where I can get it from?
Biggest will be whatever size will fit and not rub on other parts.
Best will be a matter of conjecture, dicussion, mudslinging.....and in the end prolly whatever your riding style suits
You can order tires from most any online parts supplier...they also sell them at bike stores and the like.
Honestly your probably best with the stock sizes on a stock rim
