The 50mm Malossi MHR Big Bore piston with a 12mm pin diameter is a high-quality replacement and upgrade piston for 2-stroke engines on the Minarelli AM6 and Piaggio 2T platforms. MHR stands for Malossi High Revolution — the piston is designed for better performance at higher RPMs than the original piston.
Fits engines with the Minarelli AM6 block (sport moped platform), both horizontal and vertical Minarelli versions, and Piaggio 2T scooters and mopeds. Also suitable for the Derbi Senda. Malossi part number 3413047.
When installing, ensure the correct aspen (pin diameter 12mm) and check the piston rings and cylinder for wear. Preferably combine with a matching big bore cylinder for optimal results.
