    • Our take on the トルクカム YAMAHA 50ccスクーター系 (RL-03)

    The KN Planning RL-03 is an aftermarket torque cam for the driven pulley of Yamaha 50cc scooters. It replaces the stock torque cam to change how the driven pulley shifts, which alters acceleration and top-speed behavior. It suits riders tuning a Yamaha 50cc scooter's CVT who want to change the shift curve rather than replace the whole transmission. Compared with stock parts, it is a small, targeted tuning piece; gains depend on the rest of the setup, so it works best alongside matching roller weights and springs.

    Questions and answers

    What does a torque cam change on a scooter?
    It alters the angle the driven pulley follows as the belt rides up and down. That changes the shift curve, which affects acceleration and how the scooter holds speed.
    Does it fit any Yamaha 50cc scooter?
    It is listed for Yamaha 50cc scooter drivetrains, but fit varies by model and engine. Check your scooter's driven pulley and part number before ordering.
    Do I need other parts to feel a difference?
    Usually yes. Roller weights and contra-spring rate set the shift behavior too, so the cam works best as part of a matched CVT setup.
    Is it hard to install?
    You need to remove the CVT cover and the driven pulley assembly. It is a straightforward job for someone with the right tools, but it is not a plug-and-play part.
    Will it raise top speed?
    Not on its own. It changes the shift curve; top speed depends on the whole setup, including variator, rollers and engine tuning.
    Where is the トルクカム YAMAHA 50ccスクーター系 (RL-03) cheapest?
    At バイクマン, for $35.00, as of our latest check.
