Bell Helmets Ready to be impressed? Then check out Bell's newest helmet, the "Star". Engineered from the ground up with more than three years of development, the Bell Star is simply the best Bell ever. And that's saying a lot considering Bell invented the motorcycle helmet. The feature-packed Star is equipped with Bell's exclusive ventilation system that literally pulls air through the helmet, keeping the rider's head cool and dry. The Star's visor removal method is the "no-brainer" we've been asking for. And the shield and multi-stage chin vent sends air up the inside of the specially coated shield to virtually eliminate fogging. The helmet is crafted out of Bell's super lightweight carbon fiber/Kevlar composite and is wind-tunnel proven to eliminate lift and for super stability. Contour-cut cheekpads, removable and washable, offer superior fit and comfort. We simply love these helmets and you will too! 1-800-456-BELL

Dunlop Tires What makes Dunlop the best? Overall performance. Let's face it, there's more to tires than just price. How about handling (easy turn-in, holding a line), predictability at their life's end (a little wiggle warning instead of a surprise crash?), warm up (a few corners, not two laps!), longevity, and maybe most important, grip. Try Dunlop's bargain SportMax GPA race tires at an unbelievable price. Or the ultimate DOT race tire, the D211 GPA's. Ready to step up to slicks for the best traction and longest life?  For more info on Dunlop tires, you can visit www.dunlopracing.com
