Great quality roller weights for scooters using GY6 150 engine in scooters and go carts. Lower your stock weight (12-14) with 10s or 11s for a great performance upgrade for better take and just plain replacing worn out stock weights. 18X14 mm roller set for Buddy 125, Blur, and many other scooters. Buddy 125 takes 11.5g stock rollers, and Blur takes 14g stock, so play with some different weights and make it rip! Roller weights are used for fine tuning your scooter to get the most out of what you need from your scooter. Tuning Tips: Light rollers are good for quick acceleration, stop and go riding and hills, but you loose top end speed. Heavy rollers will give you a higher top end speed (long roads) but you will loose low end acceleration. If you’re a heavy person (and/or) if you have a stock motor you will want to lean towards the lighter rollers. If you are a light person (under 140lbs) or you have a big bore you will want heavier rollers

We recommend starting performance upgrades by changing the variator roller weights first. 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. Please see our Warranty & Returns Policy.

Please select weight above. 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.Please see our Warranty & Returns Policy.
