The INNTECK OS372 crankshaft oil seal is designed for SUZUKI RMX 450, RMZ 450 from 2005 to 2027. The crankshaft oil seal seals the point where the crankshaft passes through the crankcase. On a four-stroke, it holds in the engine oil: hardened or worn, it lets oil seep along the shaft, behind the flywheel or the sprocket.
