A Cylinder Works replacement cylinder is a completely new, not remanufactured, cast aluminium nickel silicon carbide (NSC) electroplated stock bore cylinder that appears just like an OE cylinder.
NSC is a composite of 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.
Features:
- Cylinder looks just like stock.
- Nickel silicon carbide plated for longer life.
- No machine work needed *
- Replacement cylinder for standard bore only.
* Honda CRF250R and CRF250X may require slight case modification. Kit comes with instructions.
