Traditionally, the gear ratio is changed by the up-and-down rolling movement of the roller weights in the ramp of Moveable Drive Face (MDF) of the variator. Now the innovative Dr. Pulley Sliding Roller Weights slide up and down in the ramp of MDF to change the gear ratio. This unique sliding movement provides exclusive advantages to make CVT perform excellently: no abnormal wear will occur; even when Dr. Pulley Sliding Roller Weights work in the high gear position. Fits all 150cc buggies & motorscooters. These sliding roller weights are the latest design made out of extra strength nylon. They last 20% longer and are over 18% more durable. This new sliding design variator outperforms our MRP Variator by 8 points on dyno meaning that if you want to race then you need the Dr. Pulley variator design. The kit brings everything you see here including the pin, race fan, variator, cover and slide pieces. IT DOES NOT INCLUDE ROLLER WEIGHTS!
