YM318501 MALOSSI MHR REPLICA 70cc CYLINDER KIT - YAMAHA BWS 50cc AIR COOLED, MINARELLI VERTICAL 50cc 2 STROKE SCOOTER MOTORS. The Malossi MHR Replica series is a high-performance line of cylinder kits designed specifically for 50cc 2-stroke scooters, motorcycles and mopeds (peds), created with a racing pedigree in mind yet developed for road users. Originally developed for the International Scooter Trophy - Automatic Class, these kits strike a balance between maximum performance and long-term durability, making them a favourite among serious tuners and weekend racers alike. Here's what sets them apart: Aluminium cylinder with nickel-silicon carbide coating for superior heat dissipation and wear resistance. Piston with two chrome-plated rectangular rings, ensuring optimal sealing, reduced friction and excellent service life. Compression ratio of 13.8:1, delivering up to 6.6 kW (9 hp) at 8,500 rpm and 7.35 Nm of torque at 8,000 rpm. Designed for liquid-cooled & air cooled engines, with versions available for a wide range of models including Piaggio, Gilera, Aprilia, Yamaha Aerox, and Minarelli platforms. These kits are ideal for riders looking to upgrade from stock without jumping into full-blown race-only setups. They're also a great match for expansion chamber exhausts like the Malossi flip and benefit from carb and transmission tuning to unlock their full potential. Malossi part number 31 8501.
