Description
The most powerful cylinder kit ever produced by Malossi: over 32 HP at 14,000 RPM. With its large displacement, this kit is exclusively for liquid-cooled motorcycles.
Specifically designed for top-level racing, it features the latest evolution of Malossi’s iconic 7-port technology. The standout feature is the support provided to the main rear transfer ports through the use of two ports opposite the exhaust.
The cylinder has a close deck structure paired with a redesigned modular head.
The head is designed to enter the cylinder’s combustion chamber, safeguarding the nickel coating in case of detonation.
To install this thermal unit, modifications to the crankcase are required:
- In the boring area, to accommodate a crankshaft with an increased stroke and a longer connecting rod (specifically, a 47 mm stroke and a 100mm rod);
- the transfer ports need to be further matched.
The volumes and flows have been revolutionized, to unleash all the power this cylinder has to offer. No compromises: a carburetor between 30 and 34 mm is necessary. To ensure perfect synergy and maximize on-road performance, the 100 cc kit should be paired with our crankshaft, which has been renewed with a 100 mm connecting rod.
With this cylinder, the engine benefits from reduced loads on the pistons and bearings, thereby extending its lifespan. Additionally, friction is significantly minimized, resulting in increased engine efficiency, along with a notable reduction in noise and vibrations.
The exhaust system accompanying the 100 cc kit is the result of targeted engineering, designed to enhance performance and perfect the fluid dynamics of the new Malossi cylinder.
How did we achieve this? By optimizing the exhaust port angle and implementing a custommade coupling.
Moreover, to ensure an effective connection to the exhaust pipe, we have developed an ingenious flange-coupling system, which attaches to the cylinder with three cylindrical head screws and an O-ring seal at the exhaust duct. This solution, simple yet highly effective, prevents any possible leakage from the thermal unit.

Looking at the barrel, I noticed strange marks on the exhaust sleeve. Is it normal for them to be there?
This is a deliberate machining. As high temperatures are reached at this point with strong expansion, this machining was done to lower the point in order to avoid seizing.
