Technical design

• 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. Their surface is finished by cross-smoothing with two diamond passes and very limited tolerances. Production takes place on machine tools with high-precision numerical control. Newly calculated and improved heat exchange surfaces complement the structural design.

Pistons and piston rings

The ultra-compact, lightweight and reinforced piston is designed with 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

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