Specialized custom sliding roller weights for variator (front clutch). Available for QMB139 49cc and 157QMJ 150cc engines.
Upgrading Roller Weights in the variator is the simplest of upgrades and the least expensive for the consumer. The main rule for tuning variators is: the lighter the roller the more rpms are needed to push the rolls outwards through centrifugal motion to set the gear change in motion. Heavier roller weights need lower rpms to start moving. Heavier roller weights = slower take off speed, more acceleration, = higher maximum speed. Lighter roller weights =faster take off speed, less acceleration = lower achievable speed. The right balance is an individual choice. For daily use a driver might prefer lighter weights for more power to take off faster at a stop light.
