Dr. Pulley 18x14 Sliding Roller Weights for 125/150cc 4-stroke GY6 engines. 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.
Heavier roller weights= A slower take off speed with more acceleration and a higher top speed.
Lighter roller weights = A faster take off speed with less acceleration and lower top speed. -
