• ArmorGlide skirt coating — reduces friction against the cylinder wall for improved efficiency and extended service life
• Race-ready dome finish with smooth edges for improved combustion flow and optimized power output
• Computer-engineered piston skirt profiles minimize cylinder wall friction for quiet running and tight tolerances
• Optimized strength-to-weight ratio — lightweight forging delivers instant throttle response and maximum torque
• Condensed grain structure — forged material provides higher mechanical properties and superior resistance to impact and fatigue versus cast pistons
• Piston forging number: 4927M

Kit Includes:

• Forged piston (77.00mm)
• Piston rings
• Wrist pin
• Circlips
• Top-end gasket kit
