The water-cooled Malossi is THE cylinder for all large LC engines from Piaggio. Considerable increase in power despite the slightly smaller displacement on the 180cc engines. Can be increased to over 30hp with the help of a full cheek shaft, racing exhaust and a larger carburettor, making it the first choice when it comes to nothing but pure power. Can also be built as a comfortable tourer with original exhaust. Depending on the tuning level the cylinder reaches the mileage of the original cylinder.
