  Vertex Piston Kit

  When it comes to power and performance, Vertex four-stroke pistons are hard to beat. Forged from the highest quality 2618 aluminum alloy, 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.

  • With the purchase of a premium quality piston, every Vertex piston kit contains a complete set of nitride-coated or chrome-plated piston rings, a fully case-hardened wrist pin and circlips.

  Cylinder Works Gasket Kit

  • Replacement top end gasket set for Cylinder Works cylinder kits.
  • Each kit includes head, base, exhaust and cam chain tensioner gaskets.
  • To be used with Cylinder Works Standard Bore Cylinder Kit.
  • Note: Actual kit contents may vary by fitment.

  Cometic Top End Gasket Kit

  Cometic meets the needs of each specific gasket by using materials to match. Even the basic top end gasket kit features different materials for each gasket. The head gasket is constructed from non-asbestos, flexible graphite that is laminated to a stainless steel core. The manifold and base gaskets are constructed from non-asbestos nitride rubber-bound fiber. Cometic also includes copper gaskets where needed.

  Cometic designs and builds their gaskets in the U.S.A.
