MOTOFORCE OUTER FRT PULLY MF ENH.QUALITYINCL.STAR WASHER -57147493

CVT pulley with fan wheel made of aluminum with matching star pulley. Original replacement for China scooters with 2-stroke engine and 16mm Vario stump (CPI Oliver, Keeway, Generic and others).

The pulley is part of the variator and responsible for the V-belt moving outward when accelerating and moving back in when decelerating.

• For 16mm crankshaft stub

• Pulleys are an integral part of the CVT system on scooters and mopeds with automatic CVT transmission.
  The continuously variable transmission consists of fixed and moving pulleys, the V-belt rises and falls between them depending on the engine speed, changing the speed of the vehicle.

  WHEN SHOULD YOU CHANGE A PULLEY?

  There are two reasons for replacing pulleys:

• Wear and tear. Although pulleys are relatively durable, the constant sliding of the V-belt can deform the surface.
• Tuning. Different pulley angles and diameters can improve the handling of scooters or mopeds.

• Note: A CVT variator can only do a good job when CVT pulleys as well as torque drive pulleys are compatible with each other. Pitches and diameters of the individual elements must be matched so that the V-belt can glide evenly.
