mgmxkid Posted April 9, 2010 06 CRF250 Front Tire 90/100-21 OK? Is this too big? I think the 80/100-21 is stock. I am a Vet B rider and the 90/100-21 looks huge? Share this post Link to post Share on other sites
Charlie C Posted April 9, 2010 That tire will work fine. My kid will only use the 90/100-21 bridgestone up front. He also runs the Michelin 110 on the rear which the bike calls for 100's. Share this post Link to post Share on other sites
