The DYLinkar 25N Timing Chain is a standard-grade transmission chain specifically designed for the valve timing system of motorcycle engines. It features a straight plate structure and is compatible with the 25H specification chainwheel system. The 25N has the exact same size specifications as the 25H. The product undergoes strict size accuracy control and pre-stretching treatment before leaving the factory to ensure the phase synchronization accuracy between the camshaft and the crankshaft. The DYLinkar 25N timing chain is widely used in the valve timing systems of motorcycles with engine displacements ranging from 50 to 125cc.
