Build and Design

This belt is made in Japan and uses high-tensile reinforcement cords that resist stretching and hold the shift curve in place. Its high-heat compound is designed to resist glazing, cracking, and slipping across a range of riding conditions. The part number is stamped on the belt, so it is easy to look up later.

Fitting Tips

While the CVT belt is off, take a look at the roller weights in the variator and the clutch pulleys as well. Brake cleaner works well for removing residue from the case and can help keep things running properly. When pushing back the rear clutch pulley sheave to add slack, work gently and avoid tools that might harm the parts.
