With their new SportPRO variator kit, Stage6 again introduce a state of the-art tuning part into their product range!

The variator comes adjusted for use with a 50cc cylinder and a Stage6 ProReplica exhaust system although it has been developed and optimised for use with Stage6 SportPro/ Streetrace or similar 70cc sport cylinders though.

The back of the variator and the roller tracks are hard coated, the running surface is, however, uncoated. On the one hand this reduces the running surface's lifespan, on the other hand the increased friction coefficients result in better performance.
This means the coating cannot flake off, as it can happen with hardcoated running surfaces, which can lead to quicker drive belt wear or even breaking of the belt. Included in this kit are the variator with two different bushings (for 13 and for 16mm variator shafts), two back plates with low friction coating, shims, a set of roller weights (16x13) and a torque spring.

Fits Chinese 2-stroke mopeds, CPI 50cc, Keeway.
