CVT (continuously variable transmission)

A CVT keeps the engine in its most efficient rev range; the rider only uses the throttle and brakes. A scooter CVT is made up of:

• The front variator and rollers
• The drive belt
• The rear pulley, torque cam and spring
• The centrifugal clutch and bell
• The final drive gearbox (with its own gear oil)

Routine maintenance covers the belt, rollers, sliders and clutch shoes, and the gear oil is changed at the interval in the manual.
