Malossi Intake Manifold (short, straight resonance length) – 22 mm bore / 28 mm connection for Minarelli horizontal

With this Malossi intake manifold, you get a well-thought-out solution for setups on the Minarelli horizontal engine: short resonance length, straight connection, and the correct dimensions for common performance carburetors. The Malossi intake manifolds, popular for years, have been revised in their basic design – especially the small variant has been optimized.

In the small variant (for 19 and 21 mm carburetors from Dellorto), the bore was increased by 1 mm to 22 mm, while the 24.5 mm connection remained the same. For the large brother, everything remains as before: 22 mm bore and 28 mm connection – suitable for the 19mm Team carburetor and the 24mm Mikuni TM carburetor.

Malossi also offers a choice between the NBR variant and a significantly more expensive version to account for the increased and more aggressive alcohol content in gasoline in recent years.

Note: Depending on the carburetor, the rear wheel guard must be removed.
