Malossi Intake Manifold D 21/24,5 length 26,5 tilted Piaggio Gilera 50 2T

The Malossi Ø 21x24.5 inclined intake manifold is an essential component for Piaggio and Gilera 50cc 2-stroke engines. This manifold serves as an access corridor for the air-fuel mixture in the engine, allowing for optimal performance.

The overall performance of an engine depends on various factors, including volumetric, thermodynamic, and mechanical efficiency. Volumetric efficiency indicates the ratio between the amount of mixture entering the combustion chamber and the engine displacement. The intake manifold plays a fundamental role in volumetric efficiency by minimizing friction losses during the passage of the mixture.

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

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

Malossi, with its extensive 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 R&D department, both on the road and on race circuits.

Malossi rubber manifolds feature a composite structure, with an aluminum insert embedded in a plastic material resistant to oils and fuels. This ensures a rigid mounting base and good elasticity of the manifold body.

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