THE MOTORCYCLE CHASSIS is the main “body” of the motorcycle, to which the engine is attached. Consisting of the frame, wheels, suspension, and brakes, the chassis performs various functions. The frame, which is built from steel or alloy, keeps the wheels in line to maintain the handling of the motorcycle, and serves as a structure for mounting other components. The engine and gearbox unit is bolted into place, while items such as the seat, the fenders, and the fairing are more easily removable. Suspension cushions the rider from irregularities in the road surface. In most suspension systems, coil springs controlled by an oil damper separate the main mass of the motorcycle from the wheels. At the front, the spring and damper are usually incorporated in a telescopic fork; the rear employs a pivoted swingarm. The suspension also helps to retain maximum contact between the tires and the road, necessary for effective braking and steering. Drum brakes were common until the 1970s, but modern motorcycles use disc brakes, which are more powerful.
