Vertex Cast Replica top end kits put everything for a top end rebuild on your Kawasaki in one box: piston, rings, pins, circlips and top end gaskets, plus the wrist pin bearing or cam chain where applicable.

• Cast pistons are gravity cast aluminum alloy with 18% silicon content, which makes an extremely light but very strong piston.
• 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. All rings are OEM replacements.
• Replica KTM 2-stroke pistons are factory supplied to KTM.

Choosing the Right One

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