W899M05600 Piston Kit Yamaha YZ125 2022 +2.00 mm

Features: Piston Kit includes a high-quality piston ring, high-strength wrist pin and circlips. Pro-lite Kit with drop-in, forged replacement optimizes greater strength-to-weight ratio over OEM part. Additional forced pin oiling improves small end bearing and wrist pin lubrication. Armorglide skirt coating reduces skirt and cylinder wear and improves performance through reduced operating friction. Offered in +2.00 mm overbore option for higher displacement builds. GP Series features forged material and offers increased tensile strength over OEM cast components and lightening operations result in approximately 7 g weight savings over OEM. Proprietary ArmorX coating in critical areas provides highly protective thermal barrier, reducing heat-induced damage and wear, and preventing ring microwelding. Shares the same Armorglide skirt coating and pin oiling benefits as Pro-lite.
