Chapparal Motorsports

There are a few places that let you search via the tire size but motorcyclists tend to be much more anal about their tires since you have maybe 2 inches of tread touching the ground at any given time. You have 17s on both sides right? That should be an easy one. Plenty of choices to choose from. Me I'm stuck with either a Farley crappy touring tire or at best a 15 year old designed Bridgestone BT-45 duel compound (which is what I have and happy with).
I like Chapparal simple because they're priced well, and shipping is free over 100, also the tires I've gotten through them are "new" tires not the standard 3 year old crap that has been sitting. They sell a lot!
