Roller Weight Set - 16x14mm (6 Per Set) for Scooters & Mopeds

16x14mm Roller Weight Set for GY6 QMB139 50cc Scooters

This roller weight kit is made for GY6 QMB139 50cc scooters. The set contains six separate weights, each measuring 16x14mm, and can be used to tune how your scooter performs. It belongs to our range of variator and roller weight options, letting riders adjust their setup for quicker pick-up and higher speed. Pick the weight that suits how you ride and what you need from your scooter.

Build and Layout

Each roller has a tough black polymer outer casing with an aluminum inner sleeve. The mix of materials keeps the weight manageable while holding up over time. The weights slot straight into the CVT system of your scooter, so they are simple to fit during routine upkeep or when changing your tuning.

How They Affect Riding

Roller weight influences both acceleration and top speed. Lighter rollers let the engine reach higher RPM sooner, which helps with quicker take-off and climbing hills. Heavier rollers hold RPM lower, which can add speed on flat, straight roads. Choose according to whether you value stronger low-speed response or a higher cruising pace.
