ProX motorcycle piston kit for KAWASAKI 800 SX-R 03-11

• The manufacturing of ProX pistons is often similar to OEM configurations, although sometimes modified to improve performance.
• ProX pistons are exceptionally stable, made through gravity casting from an aluminum alloy containing approximately 18% silicon.
• Silicon reduces thermal expansion, playing a critical role in the performance and lifespan of the pistons.
• ProX two-stroke pistons are manufactured for both cast iron cylinders and Nikasil-coated cylinders.
• For Nikasil-coated cylinders, ProX offers different size options A/B/C/D, with differences up to 0.01 mm, for optimal fit.
• Piston diameter: 82.50 mm
• Piston size: +0.50 mm
