MALOSSI Roller Set 20x14.8mm 11.5g - 6 Pieces
Set of 6 MALOSSI rollers made from CPT with a specific formula, originally designed as a technical replacement for urban scooter variators. Precise dimensions (Ø 20 x width 14.8 mm) and a nominal weight of 11.5 g per roller for reliable gear ratio adjustment.
Operation
The rollers convert rotation into centrifugal force: the heavier the roller, the faster the outward thrust, and the earlier the variator shifts up a gear. These rollers allow you to adjust the timing of the engine speed change and the scooter's acceleration without modifying other components.
Variator Adjustment
The choice of weight affects the engine speed under load. Lighter rollers promote a higher rotational speed; heavier rollers lower this speed. Use this set to restore the expected behaviour of the variator or to test a setting suitable for your urban riding.
Examples of common models affected: HONDA SH 125 I (2025), WOTTAN STORM-T 125 (2024), SYM SYMPHONY 125I ST ABS (2024). Always check dimensions before installation.
