Piaggio Medley 125 IE S ABS (MA 01) [2016-2018] - H20 I-Tech cylinder set - Ø63mm Piaggio/Vespa

MALOSSI H20 I-Tech cylinder set with Ø 63 mm

The H20 I-Tech cylinder set from MALOSSI combines a bore of Ø 63 mm with a stroke of 58.7 mm. This results in a displacement of 183 cm³. The compression ratio is 11.48. The newly calculated heat exchange surfaces complement the precisely manufactured cylinder-piston connection with 0.05 mm clearance.

Cylinder and machining

• Primary aluminum alloy with high content of hardened and tempered silicon
• Cylinder liner with silicon carbide coating in a galvanic nickel die
• Cross smoothing with two diamond passes and very limited tolerances
• Machining on machine tools with high-precision numerical control

Pistons and piston rings

The ultra-compact, lightweight and reinforced piston has three rings. It consists of a special aluminum alloy with a high silicon content and low thermal expansion. The sliding surfaces have a tin coating. The piston is also machined on numerically controlled machine tools and has improved heat exchange surfaces.

• First ring: compression ring made of nitrided and chrome-plated steel
• Second ring: special cast iron
• Wiper ring: three-piece design made of special chrome-plated steel alloy
