MALOSSI mhr gear shaft for MINARELLI horizontal for MINARELLI horizontal/vertical 50cc 2-stroke, AC/LC pressed, Ø 22,1 mm A final strengthened and lightened crankshaft manufactured by Malossi. The hardened driveshafts are made from a special alloy, ensuring sufficient breed standard strength, although the part has less metal mass than the OE PIAGGIO item, which reduces its weight and therefore increases it's efficiency. These mhr driveshafts fit perfectly into the PIAGGIO OE crankcase and gearbox cover, with no modifications necessary.###6714748 (MALOSSI)
