MVT SC Racing crankshaft MINARELLI AM6
The MVT SC racing crankshaft is a high-performance component for motorcycles with Minarelli AM6 engines (Aprilia, Beta, Fantic, HM, Husqvarna, Malaguti, MBK, Peugeot, Rieju, Sherco and Yamaha). The MVT SC crankshaft is reinforced and is perfect for racing and high-end racing configurations.
Construction of the MVT SC crankshaft
This is a forged steel racing crankshaft with an extended 44.8mm stroke, with a high-strength polished 90mm connecting rod for 13mm piston pins, 20mm journals and 18mm crank pin. The silver-plated small end bearing improves the reliability of the crankshaft.
The crankshaft is designed for speeds of up to 16,000 rpm, making it ideal for tuned engines.
Advantages of the mvt sc racing crankshaft:
- Excellent balancing: Reduces vibrations, improves stability and ride comfort.
- Improved pre-compression: Better filling of the crankcase and more power.
- High-quality materials: Forged, polished connecting rod and silver-plated needle bearing
And if this crankshaft does not fit your engine configuration, we have a large selection of crankshafts in our store.
Pro tip: We recommend the combination with the 90 Iron Pro Max AM6 cylinder. Both components are included in the Minarelli AM6 MVT Iron Pro MAX engine package.
Requires 2x 6204 bearings, z.B. Stage6 AM6 bearings with steel cage or Stage6 AM6 bearings with polymer cage. Bitte separat kaufen.

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.
