This Naraku variator sleeve can be exchanged for the original sleeve (collar bush). The factory-fitted sleeve / collar bush blocks the variator from a certain speed / rpm and no longer changes the transmission ratio.
The Naraku racing vario sleeve has no stop and the variator can complete the full "path" of transmission ratio change to the end. As a result, top speed increases significantly and speed reduction of 45km/h is lifted.
This type of variator bush is a requirement for all further tuning measures. This part is step no. 1 and is an absolute must, if parts like cylinder, exhaust, carburettor etc. are to be changed. Suitable for the original variator.
