While changing the front sprocket, it is always recommended to inspect the countershaft oil seal that's right behind the sprocket. Positioned on the high loaded countershaft and always in contact with dirt and water, the oil seal can easily start leaking. ProX has developed a wide range of countershaft seal kits. These kits are an easy and complete replacement offering all the needed components and at the same time it is an upgrade kit resulting in improved durability against the OEM parts.
