MALOSSI Racing cylinder kit for the 125 cc Minarelli 4-stroke engines. In the scope of supply is the Force Master 1 CDI from MALOSSI. Thanks to the Force Master 1 CDI you can tune your engine despite the injection system. Four different curves are pre-programmed for different engine configurations.
The cylinder has a 58 mm bore diameter. With the original stroke of 54.8 mm this results in a stately 155 cc displacement. The compression ratio of the kit is 12:1.
The reinforced Ultra Light piston has a compact design with three rings.
All in all, thanks to the aluminium jacket, a high capacity and very durable kit. The CDI box regulates the injection system in a range of +/- 20% compared to the original injection. Thus the engine can be adapted to different tuning levels and operated safely.
