Description

Give your GY6 transmission the fixed pulley face it needs to get back to work. The Blue Line GY6 outer drive face pairs with a compatible 115mm variator, while its built-in fins move air through the CVT as you ride. If your old drive face is worn or damaged, this is the fit-focused replacement to check before you button up the transmission and head out again.

Key Features

  • Complete the variator pulley: Replaces the fixed outer drive face on compatible GY6 125cc and 150cc four-stroke setups.
  • Keep air moving: Finned design circulates air through the transmission area.
  • OEM Precision: 113.5mm outer diameter and 19 splines from an OEM-sourced manufacturer ensure this works every time.
