Piston 15 Pin 15 (70 Mm)

When it comes to engine rebuilds or high-performance bores, the piston is the heart of the operation. The 70mm Piston with a 15mm Wrist Pin is designed for riders who are serious about extracting maximum torque and horsepower from their machines. Engineered to withstand the violent forces of high-compression combustion, this piston ensures your engine runs cooler, smoother, and significantly stronger.

Why This 70mm Piston Dominates:
High-Silicon Aluminum Alloy: Cast from premium materials that offer excellent thermal conductivity and minimal expansion. This means tighter clearances and less "piston slap" even when your engine is screaming at high temperatures.

Massive 70mm Bore: Perfect for big-bore conversions or high-capacity engine restorations, providing a significant increase in displacement for noticeable gains in low-end grunt.

Reinforced 15mm Pin Boss: Designed to distribute load evenly across the 15mm wrist pin, reducing the risk of pin-bore deformation during high-load scenarios.

Optimized Ring Grooves: Precision-machined to ensure a perfect seal with your piston rings, minimizing blow-by and maximizing every ounce of combustion pressure.

Reduced Friction Coating: Features a specialized finish that reduces drag against the cylinder wall, allowing for faster revving and improved fuel efficiency.
