MALOSSI Big Bore Cylinder Kit - Ø52mm (manufacturer reference: 3115374) is a displacement upgrade designed for 50 cc scooters. Developed by MALOSSI, this Big Bore kit increases the cylinder diameter to 52 mm to modify the displacement and engine characteristics. Ideal for urban riders looking to optimize the operating range of their 50cc engine.
This kit is aimed at experienced DIY enthusiasts and equipped workshops: it often requires additional adjustments (carburetion, exhaust, transmission) to take full advantage of the new cylinder-piston assembly. Be sure to check compliance and homologation according to road use in your country before installation.
Practical points: check the condition of the original cylinder and the piston/rings assembly before installation, prepare a gasket kit if necessary, and have the timing and carburetion checked after installation. This MALOSSI kit is part of an engine preparation approach for controlled urban and sporty use.
