The cylinder is a cylindrical metal part that guides the piston to reciprocate linearly in the cylinder.Air in the engine cylinder converts thermal energy into mechanical energy through expansion, while the gas is compressed by the piston in the compressor cylinder to increase pressure.This cylinder features an integrally cast Ni-SiC composite ceramic film on the inner wall, which reduces the coefficient of friction and enhances during use.Item Type: Cylinder Kit Material Type: Cast iron Condition: Quantity: 1 Set Cylinder Dimension: STD 62mm Package Includes: Cylinder Base Gasket: 11061-0790 Cylinder Head Gasket: 11004-0734 Piston (Std): 13001-0742 Pin, Piston: 13002-0710 Piston Ring Set (Std): 13008-0047 Circlips, Piston: 92033-0732 Fits the following models: EX250 250 2013–2024 EX250 250 ABS 2013–2024 KLE250 X 250 2017–2024 ER250 Z250 2015–2024
