This Wiseco replacement piston kit is designed for the specific Yamaha applications listed below. Endurance and high rpm.

Key Features

• Endurance and high rpm.
• Each piston is electra-coated on the dome, ring groove, and pin bore, for maximum wear resistance and protection from micro-welding, galling and detonation.
• GP Series parts generally have less machining on the outside, which helps seal up the bore for increased compression.
• ArmorGlide® skirt coating reduces friction and noise for more horsepower potential.
• Kit includes piston, ring(s), wrist pin and circlips.
• Engineered, forged, and machined in the USA.
