Rollers -RMS- 20x12mm 14.0g 8pcs

The choice of rollers plays a significant role when tuning the transmission of your scooter.

In general terms:

• With lighter rollers, the scooter starts at higher RPM. Due to the higher RPM, the scooter transfers more power to the rear wheel. This results in better acceleration.
• With heavier rollers, the scooter starts at lower RPM. This allows the engine to fully use the RPM range in motion, thereby increasing the top speed.

You can choose the weight of the rollers at your discretion. Factors to consider when selecting rollers include your riding style, tuning parts, rider's weight, road or track conditions, etc.
