In 2014, Triumph embarked on a groundbreaking project to celebrate itself as the only motorcycle manufacturer to break the land speed record five times. Triumph created this revolutionary carbon fibre streamliner, featuring two turbocharged destroked Rocket III motorcyle engines.

Designed and built by engineer Matt Markstaller, the Triumph Rocket Streamliner was set to take on the Bonneville Salt Flats, a location renowned for setting speed records. Daytona 200 winner Jason Di Salvo was the first pilot to try to beat the 2010 record of 376mph. Unfortunately, the conditions on the salt meant he was unsuccessful, and sadly, the record remained unchallenged.

The second pilot to attempt exceeding the 400 mph barrier was Isle of Man TT racer and TV personality Guy Martin. He tested the streamliner in 2016 and 2017, but once again, the salt conditions thwarted all efforts, despite setting an inital record of 274.2 mph as the fastest Triumph ever. Perhaps there may be another attempt in the future, but in the meantime, this Rocket III streamliner is on loan to the Museum.
