Description
Naraku V2 Pulley GY6
The latest V2 version of the CNC-machined drive belt pulley from NARAKU. This updated version of the CNC pulley now allows mounting the original fan and starter drive plate. The pulley face angle was revised to provide a slightly higher top speed when sufficient engine power is available. The CNC-manufactured surface makes for smooth, low-vibration drive belt operation.
Unlike CNC-machined drive belt pulleys for other engine types, the HS-CNC has teeth for the electric starter. The electric starter can still be used, avoiding the effort of kickstarting. However, the teeth make the pulley slightly more expensive to manufacture.

CVT Pulleys
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.
