Also for the transmission section of the engine ProX is offering a growing range of high quality components. ProX recently started a complete line of front and rear sprockets. Sprockets are a very important item on your bike as they are THE parts that turn all that engine power into forward drive. The sprockets are always under heavy load and in combination with riding in the dirt it is important to regularly check them for wear. High quality is required here and that’s exactly what the ProX parts offer.

While changing the front sprocket it’s always recommended to inspect the countershaft oilseal that’s right behind the sprocket. Positioned on the high loaded countershaft and always in contact with dirt and water the oilseal 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.

With the installation of the rear sprocket it is never recommended to re-use the old bolts and nuts as the old bolts are usually stretched and stripped while used lock nuts are worn and can loosen up very quickly. ProX offers a nice set of 6 sprocketbolts and nuts for simple and safe fitting of your new rearsprocket!
