Athena Top End Piston Kit with Gaskets - P5F0770187009A - 2019-2023 Yamaha YZ250F

Athena piston top end kit Made Of High-Performance Aluminum Alloy With High Silicon Content That Guarantee The Same Reliability Of The OE Piston, While At The Same Time Providing Greater wear Resistance and Excellent Performance. Piston Rings Create Less Friction With The Cylinder And Therefore A Higher Performance. The Segments Included, Made In Japan, Have A Wear-Resistant Coatings (PVD Or Chromium Nitride) To Increase The Retain And The Durability.

Features:

• The high-silicon content in the high-performance aluminum alloy used in the piston kit from.
• ATHENA ensures the same reliability as the OE piston while also providing greater durability and superior performance.
• The smooth profile remains consistent with a uniform flow and optimal flame propagation.
• The Off-Road 4-stroke motorcycle pistons are produced through reverse extrusion and CNC machined
• The inclusion of wear-resistant coatings (PVD or chromium nitride) on the segments of the Piston Kit Made in Japan results in less friction between the piston rings and cylinder, ultimately leading to a higher performance. Additionally, these coatings enhance the durability of the kit to ensure long-term retention.
