Malossi RACING Manifold D 22/24.5 length 29 inclined for Minarelli horizontal

The Malossi RACING intake manifold Ø 22x24.5 inclined is an essential component for Yamaha, MBK, and Minarelli vertical 2-stroke 50cc engines. This intake manifold acts as an access corridor for the air-fuel mixture in the engine, allowing for optimal overall performance.

Volumetric efficiency, one of the main factors for the overall engine performance, indicates the ratio between the amount of mixture entering the combustion chamber and the engine displacement. The intake manifold plays a fundamental role in maximizing volumetric efficiency by minimizing friction losses along the mixture path.

In addition, the intake manifold acts as a fresh charge accumulator, allowing the mixture to compress against the reeds when the reed valve closes. This component is designed to achieve maximum performance within a specific range of RPM (tuned manifold).

In addition to these functions, the intake manifold connects the carburetor to the engine crankcase or cylinder and can also dampen vibrations transmitted from the crankcase to the carburetor, preventing fuel and air emulsion in the carburetor float bowl.

Malossi, with its years of experience in the field of engine fuel systems, has developed a new line of rubber and aluminum alloy manifolds for the latest generation scooters. These manifolds have been tested and developed by the Malossi experience department, both on the road and on the track.

In particular, Malossi rubber manifolds feature a composite structure, with an aluminum insert embedded in a plastic material resistant to oils and gasoline. This construction ensures a rigid attachment base to the crankcase and good elasticity of the manifold body.

Please note that minor modifications to the surrounding plastics may be necessary to install MHR manifolds.
