Hey guys, I purchased a 2001 xr80r to teach my sons how to ride. now that they have that covered, I want to get the bike setup for mini-moto to take on the Go-Kart track in New Jersey. I was looking at wheels. should I keep the stock rims (16" front 14"rear) and get street rubber or get different size rims. If I need to do that, where can I purchase them used or new. anything I need to do to the suspension/motor brakes, Thanks in advance!
