The Malossi 16x13 mm rollers sold in a pack of 6 are designed for automatic transmission (CVT) scooter variators. Made from CPT with a specific formula, they offer a consistent finish and controlled mass for predictable engine behavior and longevity suitable for road use.
Operating principle
In the variator, rotation transforms the mass of the rollers into centrifugal force. The 4.4 g rollers move the variator ring according to this principle: the lighter the roller, the later the gear change occurs, allowing the engine speed to rise; conversely, a heavier roller causes an earlier rise in engine speed. Adjustment is therefore made by choosing the weight suitable for your riding style and conditions (incline, load, type of journey).
Specifications
Workshop advice: replace the rollers as a complete set, check the condition of the variator tracks, and clean before installation. Use the rollers to refine the scooter's response without ever neglecting safety and compatibility with your model.
