Performance 20x12 Roller Weights for Scooters & Mopeds

Performance Roller Weights for Yamaha Scooters and Mopeds

The Performance 20x12 Roller Weights are built for Yamaha scooters and mopeds, aiming to sharpen acceleration and general responsiveness. Each set includes six roller weights with a red polymer outer shell and a brass inner sleeve. They belong to our range of scooter variator and roller weight options, and they can make a noticeable difference whether you ride up steep grades or want more speed on the flat.

Weight Options and Performance Benefits

These roller weights are available in 9g, 10g, 11g, 12g, 13g, 14g, and 15g. The lighter options (9g to 11g) typically reach higher RPMs, which helps with quicker pickup and hill climbing. The heavier options (13g to 15g) bring RPMs down and favor higher top speed, so you can choose the balance that suits how you ride.

Construction Details

Every roller weight has a hard-wearing red polymer exterior over a sturdy brass inner sleeve, which supports steady operation over time. Each weight measures 20mm across and 12mm wide, so it suits the many scooter models that call for this size.
