Big Bore Cylinder Kit

OEM appearing big bore cylinder kit containing a hand matched big bore Vertex piston and top-end gasket kit. These kits offer you an affordable way to increase horsepower while boosting horsepower and increasing engine displacement.

Cylinder Works Cylinder - new, not remanufactured, cast aluminium nickel silicon carbide (NSC) electroplated big bore cylinder that increases horsepower for a more exhilarating riding experience. NSC is a composite of a nickel and silicon carbide, providing an excellent wear resistant surface with oil retention capabilities. Cylinders are then diamond honed to the exact bore dimension and proper surface finish to ensure the proper ring seal and oil retention.

Vertex big bore piston – To handle the internal pressure of a four-stroke engine, Vertex’s big bore four stroke pistons are forged from the highest quality 2618 aluminium alloy for superior strength and durability. Vertex uses unique piston profiles and compression ratios, offered in A, B, C and D sizes to maximise power and performance while reducing blow-by and oil consumption. Each Vertex piston is then hand matched to fit each Cylinder Works cylinder perfectly.

Vertex big bore gasket kits – The gasket kit contains all the necessary gaskets to rebuild your top end. Kit includes head, base and exhaust gaskets, as well as O-rings, that are necessary when removing the cylinder and head during routine maintenance.
