Dr. Pulley Sliding Roller Weights 18x14 for 150cc, GY6

Dr. Pulley slider weights size 18 x 14 for GY6 motors (125 / 150). This product comes with six slider weights in the package.  Traditionally, the gear ratio in the CVT is changed by the in-and-out rolling movement of the roller weights.  With the innovative Dr. Pulley sliding roller weights, the roller weights “slide” inward and outward in the Movable Drive Pulley (MDF) to change/extend the gear ratio.

Dr. Pulley Sliders are a different style of roller and can be used with your stock variator. The unique shape offers a variety of benefits: 

--Sliders engage up to 20% faster than traditional rollers. They allow you to engage in higher gear ratios. 
--Sliders last longer with much less wear than rollers because they slide rather than roll (hence the name!). 

Choosing a slider weight size: 
- Lighter roller weights will give more climbing power at the consequence of losing some top end speed. 
- Heavier roller weights will allow more top speed at the serious expense of climbing ability - but are great for flat-ground racing.
