YAMAHA YZF250 YZ250F 2016-2018,
ArmorGlide WISECO 40167M07700 ArmorGlide PISTON KIT. HIGH Compression, Ratio 14.5:1
-Wiseco forged pistons are superior in strength and design. -Engineered to provide the best possible path for combustion

chamber heat transfer to cylinder walls. -Elliptically designed to provide a more uniform bearing surface under piston heat expansion, eliminating localized pressure and distributin thrust loads more evenly, thereby preventing piston collapse. -Ultra-hard Electra coating protects against erosion from detonation and keeps the piston cooler. It also eliminates micro-welding rings to the grooves and prevents galling in the pin bore.

-ArmorGlide skirt coating minimizes friction, improves wear resistance and maximizes horsepower on out high-performance applications. Complex skirt profiles reduce friction and promote stability in the bore for optimum ring seal.
