Wiseco Exhaust Valve - Yamaha Yfm660F/Yfm660R/Yxr660 Ves029

VALVE STEEL EXH YAM

• HIGH-PERFORMANCE ENGINE VALVES
• Valves are stronger and more reliable than OEM because they're forged as one unit, rather than pieced together like stock valves
• Treated with either CVD or CNI (depending on the application), both applications are wear- and friction-reducers that resist heat penetration as well
• Stainless steel valves are manufactured to exacting tolerances from the highest-grade material; coated for longevity and peak performance
• Sold each
