This Premium Double Cog Kevlar drive belt was designed specifically for the UMAX. Top cogs help keep the belt cooler which increases performance and belt life. These are much higher quality belts than the OEM belt. Don't be fooled by cheap replacement belts, if you want peak performance from your machine don't skimp out on the belt! The drive belt is one of the most important factors in getting horsepower from the engine to the ground.
