In motorsports, carbon fiber is often used to construct bodywork or a monocoque chassis. This trend started in Formula 1 and has gradually been adopted in other forms of motor racing. Carbon fiber is commonly used in aftermarket motorcycle accessories because of its high rigidity, low weight and "trick" look. These parts range from small covers and panel replacements, through to entire frames and wheels. Part of the appeal is the regular use of carbon fiber by the racing teams, making similar parts desirable by modifiers and race-replica riders, but reducing the weight and increasing the strength of motorcycle parts can allow for vast improvements in the power-to-weight ratio and suspension response of the vehicle.
