Extreme racing conditions demand the strength and toughness

that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. E 56-W8507+100.WO

strength-to-weight ratio, and maximize performance. Armor Glide Coating: Some of our forged pistons offer our new ArmorGlide? skirt coating, which is the result of testing, development, and benchmarking through Wiseco?s rigorous in- house dyno program. The outcome is the ultimate in skirt coating toughness, lubrication, and bond technology working together to minimize friction, maximize horsepower, and provide improved wear resistance. Not only is ArmorGlide? a high-tech l 56-W8507+100.WO - 1998 Yamaha XTZ 660 Tenere
