Tuning Kits for 50cc Gear bikes

In our Tuning Kits category, we offer packages containing carefully selected components for a balanced performance upgrade or a complete engine rebuild. All included parts are perfectly matched to work together.

We offer tuning, OEM replacement and derestriction kits for the most popular models on the market, including the Rieju MRT, Beta RR 50, Sherco SM-R with the Minarelli AM6 engine, as well as 50cc bikes equipped with Derbi engine.

To provide you with the best possible products, we work with renowned brands such as Stage6, Stage6 R/T, Motoforce, Motoforce Racing, MVT, Bidalot and Airsal.

Kit Contents

OEM Kits: Engine Rebuild to Original Equipment Standards

For anyone restoring an older model or bringing their original gear bike back to life, we offer kits containing the essential components for a complete engine rebuild: crankshaft, crankshaft bearings, complete cylinder kit with piston, cylinder head and gasket set.

→ Original specifications, unbeatable value, and restored reliability for up to 10,000 km.

Engine Derestriction

You just bought your first 50cc bike and want to unlock the factory-restricted performance? We offer derestriction kits that make it easy to increase both power output and top speed.

These kits typically include:

  • Unrestricted CDI
  • Derestricted exhaust header
  • Larger front sprocket (for a higher top speed)
  • Main jet

Note: Although a main jet is included, we also recommend getting a main jet kit. Depending on altitude and ambient temperature, further carburettr adjustments may be required.

Engine Tuning: Solutions for Every Performance Level

To achieve the best engine setup and optimum performance, the components must be perfectly matched. The crankshaft, cylinder and exhaust all need to work together.

That's why we offer tuning kits featuring a cylinder and crankshaft, or complete packages including a cylinder, crankshaft and exhaust (Sport, Racing or High-End) for optimum results.

→ Additional benefit: better value for money.

Note: These kits include the main components only. The carburetor and intake system must be adjusted accordingly. High-performance kits may also require modifications to the ignition and the gear ratio.

WARNING: Large-displacement cylinder kits may require engine crankcase machining.
