Performance You Can Afford for MX & XC

The Tech 4 MX is specifically designed for ATV motocross and is available in two sizes: 20×6-10 front and 18×10-8 rear. It uses a high-tech rubber compound to delivers exceptional hook-up on hardpack surfaces, plus a unique tread pattern that pulls powerfully through soft loam. The Tech 4 MX’s carcass is designed to reduce bounce and enhance high-speed control and cornering confidence.

Competitive cross-country ATV riders and racers will like the Tech 4 XC’s 6-ply rating and taller size options. The XC is specifically designed for serious trail riding and racing. It comes in taller 21×7-10 and 22×7-10 front sizes and 20×11-9, 22×11-9 and 22×11-10 rear sizes.
