Cylinder Works Big Bore Cylinder

• Product Details

  Cylinder Works Big Bore Cylinder.

  • O.E.M. in appearance, but a fraction of the price.
  • Increases horsepower and engine displacement.
  • Power increase throughout the entire RPM range.
  • New cast aluminum.
  • Nickel silicon carbide (NSC) electroplate bore which allows for tighter tolerances, lower friction, and extreme durability.
  • True bolt-on application without further modifications.
  • Note: Cylinder ONLY for some kits (can be used with Vertex piston) unless noted.

  Why Cylinder Works uses nickel silicon carbide plating.

  • Nickel silicon carbide plating is used on the cylinder bore of every cylinder, standard and big bore, in the Cylinder Works line up. The reasons for using nickel silicon carbide, as opposed to cast iron or chrome plating, are simple. Nickel silicon carbide allows for tighter tolerances between the piston and cylinder in larger bores, provides a low friction surface, is extremely durable and allows for greater heat dissipation to the water jacket. All and all, the end result is a cylinder that not only yields higher performance, but will provide enthusiasts with a durable and reliable upgrade to their bike or ATV.
