| Re: Tire Size choices in 12" (available stateside) We have had good luck running the 100/90-12s front and rear on 1.6 rims. Its not an ideal set up, but it definitely works. The 601s were awesome, it sucks that you can't find them anymore. Haven't raced on the 92s yet, but thats what I have mounted up right now. In the parking lot they don't feel quite as soft as the 601s, but still have pretty good traction |
