Description
MVT S-RACE racing crankshaft AM6
The MVT S-RACE crankshaft is a high-performance component for mopeds with Minarelli AM6 engines, e.g. from Aprilia, Beta, Fantic, HM, Husqvarna, Malaguti, MBK, Peugeot, Rieju, Sherco and Yamaha. This MVT S-RACE crankshaft is perfect for racing setups thanks to its advanced features.
Construction MVT S-Race crankshaft
This is a reinforced racing crankshaft with 43 mm stroke, with exceptional durability and performance. It also features 2x 6204 bearings and a heavy-duty forged steel connecting rod that can withstand up to approx. 18,000 rpm. The full circle crankshaft optimizes pre-compression and therefore performance. The crankshaft is perfectly balanced to reduce harmful vibrations in powerful engines.
The small end bearing has an outer diameter of 16 mm, which allows it to absorb shocks better than a cage of the original size of 15 mm. These characteristics make it an ideal crankshaft for racing configurations.
Advantages of the am6 mvt s-race racing crankshaft:
- Excellent balancing: reduces vibrations, improves stability and ride comfort.
- Improved pre-compression: Better filling of the crankcase and more power.
- High-strength materials: Forged steel construction for durability.
- Racing crankshaft: Designed for up to 18,000 rpm.
- Reinforced needle cage: 16 mm outer diameter for better shock absorption.
And if this crankshaft doesn't suit your setup, we have a large selection of crankshafts in our store.
Pro tip: To further improve the longevity of the engine, we recommend the 6204 C3 Stage6 bearing kit and a racing ignition.

How to change a crankshaft?
The crankshaft is one of the main components of the engine and is responsible for the smooth operation of motorcycle, scooter and moped, whether with two-stroke or four-stroke engine. The longevity of the engine depends not only on the proper condition of the crankshaft, but also on the fact that it is properly mounted.
For a correct installation of the crankshaft, we recommend our tutorial: Crankshaft disassembly and assembly.
How can I tell if my crankshaft is Damaged?
A broken crankshaft causes metallic noises, unusual vibrations, leaking oil seals and drastically reduces the performance of the two-wheeler. In any case, the vehicle must be stopped immediately to prevent the damage from getting worse.
Please note that whenever the crankshaft is changed and serviced, you'll have to install new crankshaft bearings.
Tuning Level: Racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
