Cylinder Kit LC Malossi MHR Testa Rossa 70cc 12mm Minarelli Horizontal

Malossi Testa Rossa 70cc Kit for Nitro / Aerox / Bws / PGO / Adly

The famous cylinder with the red cylinder head is now available: the Malossi MHR Team Testa Rossa 70cc cylinder kit for scooters equipped with a Minarelli LC engine. Designed to push performance to the extreme, this cylinder ensures maximum power and ranks among the best on the market.

Design of the Malossi MHR Testa Rossa 70cc

Based on the MHR Team II, this Nikasil-coated aluminum cylinder features 7 transfer ports, a single-ring piston, and a two-piece exhaust port. Its design optimizes engine cooling and efficiency, with a large exhaust port and a narrow central bridge that reduces stress on the piston.

The iconic red anodized, multi-screw, separable dome cylinder head, CNC-machined from high-quality aluminum, not only improves performance but also gives it a racing look that clearly announces its destiny: competition!

Unlike the flanged version, this version is stud-mounted, allowing it to be used with standard crankcases, as well as with the Malossi C-One. The crankcase requires some modification, but the installation instructions explain everything step by step.

Unlimited Performance

The Testa Rossa is no joke: 22 hp without any modifications. With the right setup—racing exhaust, internal rotor ignition, and a 28mm carburetor—more experienced tuners can push it up to 26 hp.
