Gearboxes for 50cc motorcycles

Like any mechanical component, a gearbox can wear out, become damaged or be upgraded.

In our online shop, you'll find individual gearbox components and complete gearboxes for the popular Minarelli AM6 and Derbi engines, allowing you to repair or upgrade models such as the Beta RR 50, Rieju MRT, Sherco SM-R and Derbi Senda. We stock products from leading brands including Voca Racing, Top Performances, Motoforce, as well as genuine parts from Derbi and Yamaha.

Engine Tuning and Gearboxes

The original gearbox fitted to a 50cc gear bike is designed for relatively low power and torque. After increasing the engine displacement and fitting a performance cylinder kit, the original gearset can reach its limits, while the standard gear ratios may no longer be ideal.

For this reason, tuning specialists such as Voca and Top Performances offer reinforced gearboxes with revised gear ratios to help you get the most out of your setup.

Cost-Effective Repairs

If you're working to a budget or maximum performance isn't your priority, you'll find everything you need to repair your gearbox economically:

  • Gear wheels
  • Shafts
  • Shift drums
  • Shift forks

Note: For moderate tuning, it is often sufficient to change the final drive ratio. We offer a wide range of chain kits with front sprockets and rear sprockets featuring different tooth counts from the original gearing.
