Malossi MHR Team Tesa Rossa 100cc cylinder kit for Piaggio based flange mounted RC-One & C-One crankcases.

The most powerful cylinder ever built by Malossi: the MHR Team Tesa Rossa 100cc delivers over 32 hp at 14,000 rpm, designed exclusively for liquid-cooled scooters running RC-One or C-One engines. Built for top-tier racing, this kit represents the peak of Malossi’s development in 7-port technology.

Key Features & Design:
-Flange-mounted cylinder – eliminates through-stud constraints, freeing space for optimized transfers and improved flow.
-Close-deck aluminium structure with modular head – designed to recess into the combustion chamber, protecting the nickel coating against detonation.
-7 transfer ports with revised geometry, including dual rear supports opposite the exhaust for maximum scavenging efficiency.
-Precision exhaust design – optimised exhaust port angle with a custom flange-coupling system (3 bolts + O-ring seal) to guarantee perfect sealing and flow.
-High-efficiency architecture – reduced piston/bearing loads, lower friction, less vibration and noise, while delivering maximum power output.
