Triumph 3TA

Motorcycles, scooters and quads

The Triumph 3TA, also known as the Twenty One, is a lightweight unit construction twin cylinder motorcycle with a 350cc engine. It was notable for introducing Triumph's enclosed rear bodywork, nicknamed the bathtub, and marked a new unit construction design for the smaller Triumph twins. It sat below the larger Speed Twin and Tiger models in the range and was aimed at everyday practical riding.

We recognise this model across the auction sites and keep every one we see together.

On a used one

Check the condition of the unit construction engine and gearbox, as well as the state of the distinctive bathtub bodywork which can be prone to corrosion and is often missing or damaged on surviving examples. Verify matching numbers and originality, as many have been modified or had bodywork removed over the years.

About Triumph

Triumph is a British name carried by two separate makers. Triumph cars were built in Coventry and are known for sports cars such as the TR series and the Spitfire, with production ending in 1984. Triumph motorcycles have been made in Hinckley, Leicestershire, since the brand was revived in the early 1990s, continuing a line of British motorcycles that goes back more than a century.
