Motorcycle racing (also called moto racing and bike racing) is the motorcycle sport of racing motorcycles. Major genres include road racing and off road racing, both either on circuits or open courses, and track racing. Other categories include hill climbs, drag racing and land speed record trials.

Motorcycle sport is a broad field that encompasses all sporting aspects of motorcycling. The disciplines are not all races or timed-speed events, as several disciplines test a competitor's various riding skills.
