V-belt pulleys wear out eventually, as do brake pads, centrifugal roller weights, the V-belts themselves and require replacement. The higher the mileage of the scooter, the more the pulleys frictional surfaces become worn. This adversely affects the V-belt and can lead to the danger of it tearing apart completely. As soon as you discover these inevitable signs of erosion, the pulley unit should be replaced immediately.
We have two separate versions available, produced by the people at MALOSSI, the
Standard replacement drive pulley, lower weight, no cog teeth, pressure plate included with most types.
Racing standard drive pulley, lower weight, special frictional coating for increased stability, no cog teeth, pressure plate included with most types, series drive pulley from the Overrange variator system.
SIP-TIP : For racing and sprinting purposes we recommend bead-blasting the pulleys frictional surfaces before every race for an even better performance. This increases the necessary grip between the V-belt and the drive pulley.
