Motoforce Racing pulley CPI / Keeway
The CNC-machined front pulley made from high-quality aluminum has an integrated fan wheel. The optimized flank angle improves power transfer, while the special polymer coating prevents deformation and belt slip. The result is smooth operation, reduced wear and a longer service life even under demanding conditions.
The design eliminates the need for a star washer and ensures a precise, durable fit and smooth operation with minimal wear.

Scooter CVT Kit
The CVT system of a scooter includes a number of components responsible for transmitting engine power to the rear wheel.
Variator kits consist of:
Depending on the manufacturer, CVT kits may also include one or more contra springs or a clutch and clutch bell.
The different types of CVT kits
- CVT kit original: these kits contain OEM quality CVT components, the CVT transmission can be reset to the original condition.
- CVT kit Sport: Sport transmissions differ from OEM transmissons by a lighter variator, a modified angle and a special lining aimed at improving top speed as well as acceleration. In most cases the kits come with a reinforced belt.
- CVT kit Overrange / Oversize: Oversize kits have the same improvements as the Sport variants, but are also characterized by larger dimensions and are used with a longer oversize V-belt. This configuration improves the performance of your scooter quite a bit.
To simplify the installation of a new CVT, we strongly recommend the use of appropriate tools, especially a piston stopper, which is very practical for the removal and installation of a CVT transmission.
