Depending on the purpose of the motorcycle, you can choose the right crankcase protection. On cross-country motorcycles, they prefer to put an extremely easy protection that can withstand the pressure of stones flying from under the wheel. Enduro users have to overcome other obstacles: wiped through stones and logs, force the river to. During this operation, the engine crankcase and pump with an oil filter case are risk. You can bend a frame that passes from the bottom of the engine. In some tourist enduro, the exhaust system takes place from below or there is an oil filter. At the factory, plastic protection is installed on cross -country motorcycles. She closes the lower space between the pipes of the frame. Sometimes “burdocks” are added to protect the side parts of the crankcase (oil filter, pump). This is a protection against flying stones, and when hitting a serious obstacle to Carter will not save. But made of aluminum or carbon and constructively similar protection – this is already upgrade. Less commonly on Cross, they put steel protection. Enduro at the below of the engine is also bifurcated, but L-shaped arcs are welded to protect the sidewalls of the crankcase. But they also do not tolerate strong blows. Therefore, on enduro it is necessary to put an integral casing capable of closing the lower part, and the sidewalls of the crankcase, and the front area. On some tourist enduro, such a casing is already placed in the stock. A whole casing is the best engine protection option for any motorcycle. If you do not know who in your city can carry out such work, it is enough to introduce words into the search engine, for example, the repair of motorcycles Yamaha XV 1700 Warrior, and you will receive a list of stations that are engaged in serving your “beast”, and will probably be able to install the right Carter. We also want to note that the most common material for Carter is aluminum and steel. If you do it on order, then titanium or carbon.
