Show original supplier description
The Malossi 190cc cylinder kit is engineered for enhanced performance on Vespa ET4 150, LX150, LXV150, and S150 scooters, and other models utilizing Piaggio's Leader 125/150cc engine with carbureted systems. This kit represents a significant upgrade, delivering approximately 20% more power than a stock configuration, which translates to improved torque, acceleration, and top speed. This comprehensive kit includes the cylinder, piston, rings, wrist pin and circlips, gasket, and jets necessary for installation. Specifications detail a 70 mm bore, 48.6 mm stroke, and a displacement of 187.6cc. It comes with a cylinder head and includes specific carb jets: a 115 main jet, BE4 atomizer, and a 52/140 idle jet. Replacement pistons and rings are also available separately. The manufacturer, Malossi, is renowned for Italian craftsmanship, with products rigorously tested in racing conditions to ensure suitability for everyday applications. It is crucial to note that this performance upgrade is intended for off-road use only and is not legal for use on public roads or land. Additionally, it may not be legal for use in California on pollution-controlled vehicles, and users should check local laws before installation. Performance upgrades are considered racing parts and are not covered by warranty, and may void the factory warranty. Scooter West is not liable for any damages caused by incorrect installation or misuse of performance products. This kit will NOT work on the newer 3-valve motors found in Sprint, Primavera, 946, and Fly models; for 2011 and newer Fuel Injected models, reference number M31114621 should be used.
