• Material: cast aluminium alloy, machined.
• Crown: flat top (may include small valve reliefs depending on manufacturing batch) — nominal flat combustion face for the petrol K7M/K7MF application.
• Ring grooves: three machined grooves sized for a standard top compression ring 1.5 mm, second compression ring 1.5 mm, and oil control ring (rail + expander) 2.5 mm. Grooves are chamfered and relieved to accept the specified ring heights and allow ring rotation/seat.
• Oil-ring configuration: groove accommodates an expander plus two thin rails (typical oil control setup).
• Skirt: asymmetrical reduced‑friction skirt profile, machined finish; some pistons have a protective phosphate or graphite skirt coating.
• Pin bore: machined for 19.00 mm wrist (gudgeon) pin. Design normally uses a full‑floating pin retained with circlips (pin may or may not be supplied with the bare piston).
• Internal features: may include oil passages or pockets behind the oil ring land and lightening pockets inside for weight control. Pistons are typically weight‑matched and stamped with bore/size/position markings.
• Orientation marks: arrow or stamped mark to indicate crown orientation (arrow points to timing/front).
