Powering the Performance of Powersports Vehicles

Continuously Variable Transmission (CVT Belts) Belts are designed to seamlessly perform throughout a continuous range of effective gear ratios. They are often used in motor vehicle drive systems such as ATVs, UTVs, Side-by-Sides, and Snowmobiles in the powersports industry, scooters, motorcycles and cars more widely.

Our market-leading range of CVT belts by Ultimax features extra-strong aramid and carbon cord, fibre loaded rubber materials and a unique double cog design for maximum tensile strength, reduction in belt failure modes and better performance than any other CVT belt on the market.
