I might be getting a yamaha yz85 Big Wheel, and i am going to look at one on saturday and i need to know how to tell the difference between a big wheel and small wheel. So can anyone please tell me how i can tell weather it is a big or small wheel???. The big wheel will have a 16" front wheel and the regular YZ will have a 14". The tire size is the only difference, hence the whole big wheel thing.
