Piston 15 Pin 15 (68 Mm)

The 68mm Piston with a 15mm Wrist Pin is the gold standard for riders looking to rebuild or bore out their engine for enhanced performance. At 68mm, this piston offers the perfect balance between increased displacement and wall thickness reliability. Whether you're refreshing a high-mileage engine or building a custom street machine, this piston provides the structural integrity needed to handle high-RPM stress and intense thermal cycles.

Why This 68mm Piston Stands Out:
Precision CNC Machining: Every curve and groove is machined to micron-level tolerances, ensuring a flawless fit within your cylinder bore for maximum mechanical efficiency.

Optimal Heat Dissipation: Cast from a high-silicon aluminum alloy, this piston effectively pulls heat away from the combustion chamber, protecting your engine from pre-ignition and "knocking."

Strengthened 15mm Pin Bore: Specifically designed for engines using a 15mm connecting rod small-end, the reinforced pin boss prevents flexing and premature wear under heavy throttle.

Reduced Reciprocating Weight: Engineered to be lightweight without sacrificing structural strength, allowing your engine to rev more freely and reducing vibration at high speeds.

Superior Oil Retention: Features micro-grooves on the piston skirt that hold a thin film of oil, drastically reducing friction during those critical cold starts.
