More info

This variator sleeve is replaced with the sleeve with collar that was originally installed at the factory. The factory-installed sleeve has a stop that blocks the adjustment of the variator from a certain speed/speed and no longer changes the gear ratio.

The Naraku Racing Vario sleeve has no stop and the variator can complete the full "path" of the gear ratio change to the end. As a result, the final speed increases significantly and the speed reduction of 45km/h is canceled.

This sleeve is a prerequisite for all further tuning measures. This part is step number 1 and an absolute must if parts such as cylinders, exhaust, carburettor, etc. need to be changed. Suitable for the original variator.

Dimensions:
Length: 49mm
Outside diameter: 20mm
Inner diameter: 15mm
