The H20 I-Tech cylinder set is designed for the Vespa GTS 125 I-GET from 2020. With a bore of Ø 63 mm, 58.7 mm stroke and 183 cm³ displacement, the cylinder set is intended exclusively for use in competition on designated routes.

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. A crossed smoothing with two diamond passes and very limited tolerances completes the design. Machining is carried out on machine tools with high-precision numerical control. Newly calculated and improved heat exchange surfaces support the thermal design.

Pistons and piston rings

The ultra-compact, lightweight and reinforced piston has three rings. It is made from a special aluminum alloy with a high silicon content, which has low thermal expansion. There is a tin coating on the sliding surfaces. 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
