Tested and developed with the assistance of the factory Yamaha and Kawasaki race teams, the QuadCross MX PRO is designed specifically for very hard-packed, blue-groove type motocross racetracks. The QuadCross MX PRO utilizes designs that have resulted in significantly better performance than the original QuadCross MX tire. A revised shoulder profile greatly improves cornering predictability and side bite, while a specially formulated soft rubber compound finds traction for excellent acceleration and braking on the slickest of surfaces. The front QuadCross MX uses a dual-ribbed dimpled knob pattern that steers precisely with a very light feel and reduced lateral roll.
