This is the Dr. Pulley 21x17 Round Roller Weights, 169-327 the Aprilia Atlantic 200/250 and Scarabeo, Piaggio Beverly 200/250, Liberty 200, X8 200, X9 200 and X9 250 Evolution, Vespa GT, GTS, GTV 250/300 and many more.
Traditionally, gear ratio is changed by the up-and-down rolling movement of the roller weights in the ramp of the Moveable Drive Pulley (MDF).
Now the innovative Dr. Pulley Sliding Roller Weights slide up-and-down the ramp to change the gear ratio. This unique sliding movement (not rolling) provides exclusive advantages to increase CVT performance. With Dr. Pulley, no abnormal wear will occur even when running in high gear.
Dr. Pulley's U.S. Patent Number 7,276,004 states that their sliding roller weights eliminate abnormal wear, prevent reduction gear ratio deterioration, prolong the useful life of the transmission, and have the availability to adjust reduction gear ratios as well as driving performance. At the same time, Dr. Pulley Sliding Roller Weights are also adapted to compensate wear automatically, to adjust by itself to move further outward in a movable drive pulley half and to make the vehicle reach a higher maximum vehicle speed.
