Zuma 125 Top Speed Torque Driver
3/19/2021 update: this product is no longer manufactured. We bought out the remainder stock. Once sold out that's it.
Zuma 125 plagued with belt failure riding at speeds over 65mph? Gone is the fat weld near center of the torque driver. Now the belt can safely ride down to the bottom without failure. Also added fins on the back to help cooling. Includes two internal slots, one exactly same as stock, curved for smoothness. Second is a straight slot for performance. Better mid range and re-throttle response.
