Malossi BIG DEPS 4 MHR aluminum cylinder D 47 piston pin 12 for 3118213

The Malossi BIG DEPS 4 MHR Ø 47 cylinder is a high-quality product designed for Piaggio mopeds.

This cylinder has unique features that distinguish it from the BIG DEPS range.

It is made of aluminum with a nickel-chrome coating on the barrel, ensuring greater strength and durability over time.

The central core has been redesigned to offer even better performance.

The front part of the cylinder is machined with high-precision diamond tools and has 4 holes for fixing the exhaust flange.

Thanks to these features, the cylinder offers a significant increase in performance.

In addition, external centering has been applied, a coupling and centering strategy between the cylinder and the head that guarantees reliability and safety.

This technique allows for precise coupling without the use of additional interface components, such as bushings, and takes advantage of areas of the cylinder that are normally free of additional stresses.

The material used is a primary alloy of silicon-enriched and stabilized aluminum.

The cylinder is equipped with a flanged exhaust connection, updated intake transfers, and a completely centered exhaust transfer with a reprofiled bridge.

The piston is single-ring and the head gasket is made of annealed aluminum.

The cylinder is fixed to the crankcase by 4 studs and the head is completely redesigned.

The coupling between the head and the cylinder is guaranteed by high-precision external centering.
