Moped Transmission

On a moped, the drivetrain consists of two parts: the clutch, which sits directly on the crankshaft and drives the V-belt (with or without a variator), and the chain kit (final drive consisting of front sprocket, chain, and rear sprocket).

We are focusing here on the drivetrain of classic mopeds with automatic transmissions (Peugeot 103, MBK 51, Piaggio Ciao, Derbi Variant, etc.). For mopeds with manual transmissions (such as Puch or Simson), please refer to the explanations for motorcycle manual transmissions.

The front and rear sprockets have a direct influence on top speed and acceleration. A short gear ratio provides good acceleration at the expense of top speed, and vice versa.

Moped Drivetrain - Maintenance and Tuning

The final drive of a vintage moped must be maintained and can be optimized.

Transmission Maintenance

To properly maintain the transmission and all related components, refer to the owner's manual or maintenance guide. There you will find a lot of useful information: maximum chain wear limits, standard dimensions, etc.

To extend the life of your chain kit, it is recommended to clean and grease the chain regularly (a well-lubricated chain even contributes to your vehicle's performance by reducing friction losses in the transmission).

The chain guide and swingarm slider should also be replaced regularly. The chain tensioners must be functional to ensure precise adjustment of the chain tension.

Transmission Tuning

The easiest way to modify the transmission is to adjust the final drive ratio (chain kit). A longer ratio provides more top speed, while a shorter one ensures better pull.

For mopeds like Simson, it is also possible to swap the gears. Both complete gearboxes and individual parts with modified gear ratios and reinforced components are available from well-known manufacturers.

Moped Transmission Parts in Our Shop

In our online shop, we offer everything necessary to repair, maintain, and optimize your moped's drivetrain.
