Description

MVT SC G2B Racing crankshaft MBK 51

The MVT SC crankshaft MBK 51 G2A is a high performance component for MBK 51 motorcycles with original crankcase (G1 and G2A) and AV10 engine. This crankshaft is perfectly designed for the MVT S-Race cylinder 50cc and is suitable for setups that require high strength, for 50cc motorcycles or more.

Construction MVT SC moped crankshaft

MVT offers a racing crankshaft made of high-strength forged steel with 41.8 mm stroke, reinforced connecting rod and piston pin bearing, which is designed for high loads and a long service life. The crankshaft is designed for 13mm piston pins and allows the optional installation of a 12x17x14 mm needle cage for 12mm piston pins, which is available separately. The variator stub has a diameter of 16 mm and is therefore compatible with CVTs from well-known brands such as Malossi, Doppler and Bidalot.

Professional tip: For a longer service life of the engine, we recommend the 6303 C3 + 6204 C3 bearing kit with seals. Available separately in our store.

Notes and Safety

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.
