Malossi MHR RC-One 100cc Crankcase Piaggio Scooter

Malossi crankcase MHR RC-One 100cc for Piaggio Scooter.

Designed to fit the 100cc MHR cylinder without the need for further adaptations, this crankcase is plug & play ready for installation, finished with CNC machining to ensure maximum reliability and performance.

Together with its MHR FL 100cc cylinder, the power can exceed 35 horsepower with no need for boring, making it undoubtedly one of the best current options for competition. Compared to its predecessors, this crankcase can indeed reach 100cc without additional parts. Nevertheless, we recommend installing the full Malossi MHR kit to achieve maximum performance.
