Malossi X K Belt V-belt – durable tuning belt for many 50cc scooters

The Malossi X K Belt is a V-belt for sport-oriented scooter setups – developed for high stress and particularly high tear resistance. This is a crucial point especially for highly tuned engines, as the belt must permanently transmit a great deal of power.

Important to know: Due to the aramid insert, slipping may occur (based on experience) – particularly during the starting phase, when the gear ratio is still very small and a correspondingly high amount of force acts on the rear converter. Therefore, precise tuning is mandatory.

Advantages & Tuning Notes

• Very durable & tear-resistant – ideal if your setup can/must handle more power
• Aramid insert for high load capacity
• May slip during startup (depending on the setup)
• Recommendation: install a harder contrast spring
• Almost indispensable: tune the variator accordingly
