JASIL Roller Weights 15x12mm 4g - 6 pieces (manufacturer part number 6068002): a set of rollers designed for urban scooters to adjust the transmission and refine the variator response. Made from abrasion-resistant technical polymer and capable of withstanding high temperatures, these rollers offer a balance between durability and road behavior, while remaining easy to replace during maintenance.
Choosing the right roller weight affects engine RPM, acceleration, and torque management during recovery: lighter rollers favor a higher peak RPM, while heavier rollers increase inertia for a smoother response. Each roller has its weight marked for quick and easy installation without doubt. This JASIL set is particularly suited for routine variator maintenance and is a reliable option for riders looking to achieve precise transmission on their scooter.
