VESPA GTS SUPER 125 [2017-2018] - H20 I-Tech cylinder set - Ø63mm Piaggio/Vespa

Malossi H20 I-Tech cylinder set with Ø 63 mm for Vespa GTS Super 125

The H20 I-Tech cylinder set from Malossi is intended for the VESPA GTS SUPER 125 built in 2017-2018. With a bore of Ø 63 mm, 58.7 mm stroke and 183 cm³ displacement, it offers a clearly defined technical basis for competitive engine design. The compression ratio is 11.48.

Cylinder and machining

• Bore: Ø 63 mm
• Stroke: 58.7mm
• Displacement: 183 cm³
• Compression ratio: 11.48
• Cylinder-piston clearance: 0.05 mm

The cylinder is made of a primary aluminum alloy with a high content of hardened and tempered silicon. The cylinder liner has a silicon carbide coating in a galvanic nickel die. The raceway is characterized by crossed smoothing with two diamond passes and very limited tolerances. Machining is carried out on machine tools with high-precision numerical control. Newly calculated and improved heat exchange surfaces complement the design.

Pistons and piston rings

The ultra-compact, lightweight and reinforced piston features three rings. It is made from a special aluminum alloy with a high silicon content, which has 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, made of special chrome-plated steel alloy

The special rings are designed for high sliding properties and very high mechanical resistance.
