Triumph Rocket Iii Roadster
The Triumph Rocket III was introduced in 2004 as the world's largest-displacement production motorcycle engine at 2,294cc, a title it held for over a decade. A major redesign came in 2020 with the Rocket 3 R (Roadster) and Rocket 3 GT, featuring a new 2,458cc inline-three engine with significantly improved power and reduced weight. It remains notable as an engineering statement piece, combining massive torque with surprisingly capable handling for a cruiser of its size.

What Buyers Should Know
World's Largest Engine
The Rocket III packs a massive 2,500cc inline-triple engine — the largest displacement production motorcycle engine ever made. This gives it 167 lb-ft of torque, more than many sports cars.
Watch the Final Drive
Earlier models (2004–2019) are known for shaft drive clunking and occasional final drive seal leaks — inspect these carefully on used bikes. The redesigned 2020+ model largely resolved these issues.
Strong Resale Value
The Rocket III holds its value exceptionally well due to its unique status and limited competition in the segment. Well-maintained examples typically retain 70–80% of value after 3 years.
