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.
