FAQs

How do I know if this belt fits my scooter?

Verify your model name and engine size against the list of compatible models (Peugeot 50cc Ludix/Speedfight) and check your existing belt's part number.

How often should I replace the transmission belt?

Most manufacturers recommend inspecting the belt every 3,000 to 5,000 miles, replacing it if there is visible wear, cracking, or loss of width.

Do I need special tools to install this belt?

Yes, a variator locking tool is highly recommended to safely remove the nut from the crankshaft without causing damage.

Does this belt require a 'break-in' period?

It is best practice to ride gently for the first 50 miles to allow the belt to seat correctly in the pulleys.

Can I use this belt on a modified (big bore) engine?

This belt is designed for stock Peugeot 50cc specifications. Using it on highly modified engines may result in premature wear.

Troubleshooting

Slipping during acceleration

Check the belt for correct tension and ensure no oil or grease is present on the pulley faces.

Top speed is lower than usual

Inspect the belt width; if the belt has worn down significantly, it will not ride high enough in the pulleys to reach top gear.

Excessive noise or vibration

Check for debris inside the transmission housing or verify that the belt is not installed backwards if it has a directional arrow.

Pros and Cons

Setup, Compatibility & Care

This belt is compatible with several Peugeot 50cc models, including the Ludix Blast RS12, Speedfight 2, and Speedfight 3.

Installation Tips:

  1. Ensure the scooter is on a secure center stand.
  2. Remove the transmission cover carefully to expose the variator and clutch assembly.
  3. Use a proper variator holding tool to avoid damaging the crankshaft components.
  4. Ensure the belt is properly seated in the rear pulley before attempting to start the engine.

Care Instructions: Regularly inspect the belt for signs of fraying, cracking, or 'glazing' (a shiny, smooth appearance on the side walls). If you notice any of these signs, replace the belt immediately to prevent snapping, which could cause damage to the transmission casing.
