I just bought a kz55o and it didnt have a back tire on it. I tryed to call a couple local dealerships to see if they could give me the tire size but most of them laughed at me saying they didnt even have service manuals for that bike.

So my question is what is the stock rear tire size for a 81 KZ550 LTD with a 16in rim. Also can you safely go with a wider tire and if so wat size. Thanks Guys
