NMAX Cylinder Set 14pin 63mm

Enlarged bore. Stronger midrange. OEM-fit machining.

This Cylinder Kit for Yamaha N-MAX features a cast-aluminum cylinder with a Ø63 mm bore and 14 mm piston pin. The increased bore supports a larger displacement, delivering stronger torque potential and acceleration when paired with correct fueling and ignition adjustments. Each component is precision-machined to OEM specifications for reliable sealing and straightforward assembly.

Highlights

  • Ø63 mm Bore — Expands displacement for improved pulling power with proper setup.

  • 14 mm Piston Pin — Common high-strength spec for performance durability.

  • Aluminum Cylinder Body — Lighter weight and faster heat transfer compared to cast iron.

  • Precision OEM Fit — Machined deck height, stud bores, and spigot match OEM tolerances.

  • Complete Package — Includes piston, rings, pin, clips, and gasket for a full rebuild.
