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.

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.
