Vertex Four-stroke Pistons


When it comes to power and performance, Vertex four-stroke pistons are hard to beat. Vertex pistons are perfectly suited to handle the rigors and high pressures of today's modern four-stroke engines. Plus, to aid in the break-in process and reduce wear, every Vertex piston utilizes a unique Molybdenum Disulphide (MOS2) coating on the piston skirt.

  • Heat-treated with a T-5 hardening and tempering cycle.
  • Piston skirts are coated with a high-tech Molybdenum Disulphite coating for faster break-in time and increased piston life.
  • Cast piston kits are gravity-cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston.
  • Forged pistons are forged from 2618 aluminum for superior strength and durability.
  • Forged High Compression pistons improve power and torque across entire RPM range.
  • Forged Replica pistons are forged O.E. replacements.
  • Replica pistons and all rings are O.E.M. replacements.
  • Kits include piston, rings, wrist pin and circlips.
