Technical features

• Bore: 63mm
• Stroke: 58.6mm
• Displacement: 182.67 cm³
• Compression ratio: 11.15:1

The cylinder is made of a primary aluminum alloy with a high proportion of hardened and tempered silicon. The cylinder liner has a silicon carbide coating in electroplated nickel form. A crossed smoothing with two diamond passes and very limited tolerances completes the design. Machining is carried out on numerically controlled machine tools. Recalculated and improved heat exchange surfaces are part of the design.

Pistons and piston rings

The ultra-compact three-ring piston is made of a special aluminum alloy with a high silicon content and low thermal expansion. The sliding surfaces have a tin coating. The piston is reduced in weight and reinforced; its heat exchange surfaces have also been improved. The ring set includes a nitrided and chrome-plated I-compression ring, a special cast ring and a three-part wiper ring made of special chrome-plated steel alloy.
