Hi can someone just explain what a aftermarket torque drive does. As they sound as if there money well spent/ Thanks lads I belive this is the same as a torque drive http://scooter-center.com/catalog/produ ... 2_242_3228 looks like something i had when i took my clutch system apart
the angle of the pin ramps is diff. when you compress the clutch (pull the pulley forward) it rotates, the ammount an aftermarket item rotates is diff meaning torque is used more efficiantly. deffo worth getting on a 50/70 tho on a 125 there is marginal diff.
