Each kit consists of cylinder, complete piston and head gasket set, and is the result of the best construction technology that has previously already made Vertex pistons famous on every racing terrain.
Parallel to the Replica version Kits, which thanks to the High Compression version piston stand as a high-performance alternative to the respective original models, there is also the line of Big Bore Kits with increased barrel diameter that thanks to the increase in displacement brings the engine a significant increase in performance.
Big Bore Kits
OEM appearing +1mm to +4mm big bore cylinder kits, a hand matched, forged Vertex big bore piston and top-end gasket kit priced from $599.95. These kits offer you an affordable way to increase horsepower and engine displacement without giving your secret away to your competition.
Cylinder- new, not remanufactured, cast aluminum nickel silicon carbide (NSC) electroplated big bore cylinder that appears just like an OE cylinder. 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 pressures of a four-stroke engine, Vertex's big bore four-stroke pistons are forged from the highest quality 2618 aluminum alloy for superior strength and durability. Vertex uses unique piston profiles and compression ratios, offered in A, B, C and D sizes, to maximize power and performance while reducing blow-by and oil consumption. Each Vertex piston is then hand matched to fit each Cylinder Works cylinder perfectly.
Gasket kits- These kits contain the necessary gaskets to rebuild your top end. Kits include head, base, exhaust gaskets, and o-rings necessary when removing the cylinder and head during routine maintenance.
Standard Bore High Compression kitsOEM appearing stock bore cylinder kits containing a hand matched high compression forged Vertex piston, and top-end gasket kit priced from $559.95. These kits offer you an affordable way to increase horsepower while maintaining stock engine displacement.
