Vertex piston kits are OEM replacement pistons for Honda engines. Every kit includes the piston, rings, wrist pin and circlips.

• Cast Replica pistons are gravity cast aluminum alloy with 18% silicon content, which makes an extremely light but very strong piston.
• Forged Replica pistons are forged OE replacements made from 2618 aluminum for superior strength and durability.
• Forged High Compression pistons improve power and torque across the entire rpm range.
• Piston skirts are coated with Molybdenum Disulfide for faster break-in and longer piston life.
• All pistons are heat treated with a T-5 hardening and tempering cycle. Replica pistons and all rings are OEM replacements.

Choosing the Right One

• Select your bike under Model.
• Pick the Piston: Cast or Forged, stock or high compression, then the bore size and the size letter (A, B, C) that matches your cylinder.
• Check fitment with the bike selector before you order.
