PERFORMANCE BELTS

Pro Drive Belt by Ultimax®. Outside Circumference: 43-7/8". Top Width: 1-19/64". Weight: 1.2". 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 new cog design dissipates heat and aids flexibility. A cooler running belt delivers enhanced performance and longer belt life. Decades of advancement and experience are built into every Ultimax belt. Ultimax PRO is designed with high-strength materials to handle every riding style from ditch-banging, to deep powder to trail riding. Over a million miles a year of documented field testing ensure that Ultimax belts stay ahead of the pack in value and performance.
