V-belt Naraku 788mm for scooters with139QMB/QMA engine (long engine block)

The V-belt is one of the central elements in a variator. It enables the continuously variable transmission and transfers the power to the rear wheel. The only problem is that, along with the centrifugal clutch, the V-belt is one of the few wearing parts in the otherwise virtually maintenance-free variator and therefore needs to be replaced regularly.

We offer a new Naraku V-belt, which is designed for original and lightly tuned 50cc scooters.
A racing belt is recommended for more heavily tuned vehicles in order to meet the increased requirements.
