Ultimax PRO features a thicker cross section so more surface area contacts the clutch. This means less slippage over a broader speed range for quicker acceleration. The cog design dissipates heat and aids flexibility. A cooler running belt delivers enhanced performance and longer belt life. One Year Warranty. Proudly made in the USA.
