- Compression Ratio: 12.9:1
Cylinder Diameter (mm): 96.00
OEM appearing stock bore cylinder kit containing a hand matched high compression forged Vertex piston, and top-end gasket kit. These kits offer you an affordable way to increase horsepower while maintaining stock engine displacement.
- Cylinder- new, not remanufactured, cast aluminum nickel silicon carbide (NSC) electroplated stock 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 high compression piston- To handle the internal pressures of a four-stroke engine, Vertex's high compression 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, 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 the top end. Kits include head, base, exhaust gaskets, and O-rings necessary when removing the cylinder and head during routine maintenance.
