The BSA/Triumph racing triples were three cylinder 750 cc racing motorcycles manufactured by BSA/Triumph and raced with factory support from 1969-1974. There were road racing, production racing, endurance racing and flat track variants. The machines were based on the road-going BSA Rocket 3/Triumph Trident.
BSA/Triumph reputedly had a $2 million racing budget for 1970/1.[1]
