1 / 3 High-Speed Pulley & Torque Camshaft Kit High-Speed Pulley & Torque Camshaft Kit High-Speed Pulley & Torque Camshaft Kit High-Speed Pulley & Torque Camshaft Kit Product # 02-01-0380

This is a high speed pulley and torque cam kit for both stock engine and S-stage 156cc / 161cc motorcycles.
It not only increases the top speed but also improves the mid-range acceleration response.

■High speed pulley
It is designed by calculating the best balance of the moving line of the weight roller and the drive belt that moves with it, so that the performance of the engine can be fully extracted and the maximum speed can be improved while maintaining the stable output.The pulley body is made of die-cast aluminum to form smooth roller grooves and to enhance strength while being lightweight.

■Torque Cams
With the stock torque cam, the rotation may drop during shifting, and the output performance of the engine cannot be transmitted sufficiently.The torque cam included in the kit prevents the rotation from dropping during shifting and ensures the transmission of the output performance to obtain strong acceleration or re-acceleration.In addition, there are two kinds of slits in the body of the torque cam, and it is possible to adjust the effect of the torque cam by the use of the bike and the change of the intake and exhaust system.
