The Triumph Rocket III is a three-cylinder motorcycle made by Triumph Motorcycles Ltd. At 2,294 cc (140.0 cu in) it had the largest-displacement engine of any production motorcycle until 2019 when Triumph released the Triumph Rocket 3.
The name "Rocket III" is derived from the 1968 BSA 750cc pushrod triple, the Rocket 3, which was a badge-engineered version of the original "Triumph Trident."
