Product Details
Dr. Pulley 25x22 Sliding Roller Weights for the Aprilia Atlantic 500 ('01-'04), Aprilia Scarabeo 500 ('03-'06), Carter GT250 Buggy, Piaggio Beverly 500 ('02-'04), Piaggio X9 500 ('01-'02), Piaggio X9 Evolution ('03-'05), SYM RV250, SYM Citicom 300i ('14-'17) and many more. Please note: you should verify your roller weight size before ordering as some models may use a different size roller weight. Please select weight from drop-down menu. 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 for 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. Please see our Warranty & Returns Policy.
