These MALOSSI HTRoll rollers, made from CPT with a specific formulation, are a technical replacement part originally designed for the CVT transmission of scooters. Supplied in a set of 8, they allow for the adjustment of the variator setting to fine-tune the shift RPM and acceleration response without altering the engine architecture.

Main features:

• Diameter: 25 mm
• Width: 14.9 mm
• Unit weight: 8 g
• Number of rollers: 8 (complete set for variator)
• Manufacturer: MALOSSI – Reference: 6613561.P0

Operation and use

When rotating, the weight of the rollers generates the centrifugal force that controls the rise of the variator slider. Lighter rollers promote a higher operating RPM, while heavier rollers lower the RPM. These HTRoll rollers are intended for those who want to finely adjust the acceleration curve, response, and low-end behavior, while maintaining a standard setup.

Installation recommended by a professional or a skilled DIYer: check the condition of the variator, clean the groove, and follow the manufacturer's recommendations during replacement.
