Malossi aluminum cylinder D 58 piston pin 15

The Malossi Ø 58 aluminum cylinder is a high-quality product designed to improve the performance of your 4-stroke engine.

With a bore of Ø 58 mm and a stroke of 57.9 mm, it has a displacement of 153 cc.

Made with a primary alloy of silicon-enriched aluminum, the cylinder features a silicon carbide coating in a galvanic nickel matrix and cross-hatch honing with two diamond passes, ensuring exceptional strength and durability.

The precision machining on CNC machines ensures a perfect fit with the piston, with selected couplings with a tolerance of only 0.05 mm.

The heat exchange surfaces have been recalculated and enlarged to ensure better heat dissipation.

The piston, super compact with three segments, is made with a special primary alloy of low thermal expansion silicon aluminum, with tin coating on the sliding walls.

The piston has also been machined on CNC machines to ensure optimal precision and strength.

In addition, it has been lightened and reinforced to improve overall engine performance.

The heat exchange surfaces have also been enlarged to ensure better heat dissipation.

Finally, the cylinder rings are of high quality and designed to ensure excellent compression and high mechanical strength.

The compression ring is made of high-flow nitrided special steel, while the 1st oil scraper is made of chromed spheroidal cast iron S10 and the 2nd oil scraper is made of three pieces of chromed alloy steel.

These rings ensure effective lubrication and prolonged engine life.
