A cylinder is the part of a motorcycle where the magic of transformation of an air-fuel mixture into the energy of movement takes place. Depending on the model of the motorcycle you have and the type of its engine, the cylinder may have from one to six cylinders placed in a row, opposite to each other or arranged in a V-shape configuration. Together they form the combustion chamber – the key part of your engine that has a direct impact on its power output and also influences the fuel economy and performance characteristics of your iron horse.
When your motorcycle engine is running, your cylinders experience an extreme amount of stress. They are subjected to the constant explosion of an air-fuel mixture and high friction caused by up and down movements of pistons. All this slowly ruins the inner surface of the cylinder and wears it out until the gap between the piston and cylinder walls becomes too large, so the piston rings can't work properly and begin leaking. If so, such a cylinder needs to be remanufactured or replaced with a new one to ensure safe and efficient operation of your engine, as well as proper fuel consumption.
The soundness of the motorcycle cylinder outer surface is also important. Whereas today more and more motorcycles have a liquid-cooled engine, many of them, including cruisers and scooters, still rely on the oncoming airflow. If you have an air-cooled bike and will give a closer look at its cylinder, you’ll see plenty of fins on its walls. These fins help the cylinder cool down faster by increasing the contact area between the cylinder surface and air. And if there is a damage to the fins due to a collision or any other reason, your engine may overheat. So, a timely replacement of a faulty cylinder is of utmost importance. In view of this, we offer a broad selection of premium-grade cylinders that will help ensure dependable operation of your two-wheeled friend.
