This cylinder liner is designed as a direct replacement part for CBR400, CBR23, CB-1, and CB400 motorcycle engines.Made from cast iron with a ceramic composite coating, it offers temperature resistance, corrosion resistance, and self-lubricating properties.The inner wall features a Ni-SiC ceramic layer with embedded ceramic particles (0.3μm in diameter) that create a fine microstructure to reduce friction.These characteristics contribute to improved thermal stability, reduced wear, and extended engine service life.The part meets ISO9001 quality standards and installs without modification to compatible engine systems.
