This variator bush will be used in place of the original bush with collar. This eliminates the speed restriction of 45 km/h and the scoot can reach its intended speed (about 70-75 km/h for two-stroke scoots). This bush is mandatory if you are planning to use further tuning parts such as cylinder, exhaust, carb etc. as otherwise the engine will be damaged. 20x 38mm
