The fender is the alloy or fiber cover sitting on the motorcycle’s wheel. It connects with the motorcycle either on the sides or directly onto the top frame. The connections can be through simple nut-bolts or in certain cases will be through welding too. In most designs, you will get these fenders on both motorcycle wheels. However, the front and rear fenders differ in their size and also their attachment methods. And why do motorcycles have fenders? Motorcycles have fenders in their wheels mainly because to provide fork support, dirt and mud protection, and manage air drag for a smooth ride.
