Triumph re-entered the 350 class in 1957 with the introduction of the Twenty One, its arrival ushering in Triumph’s unitary construction era. Readily distinguishable by its Shell Blue metallic finish and ‘bathtub’ rear enclosure – a feature later applied to Triumph’s larger models – the newcomer was renamed ‘3TA’ in September 1958. With just 18.5bhp on tap, Triumph’s smallest twin lacked the urgent acceleration of its larger brethren, but nevertheless was a capable tourer good for around 80mph while delivering excellent fuel economy. ‘One of the swiftest standard British-made 350cc roadsters tested by Motor Cycling, the Triumph Twenty One combines an untiring zest for high-speed cruising with safe handling and a remarkably economical fuel consumption,’ reported the ‘Green ’Un’.
This superb example is a matching numbers 3TA and was produced in 1964. The current vendor has had the motorcycle fully restored during his ownership. The paintwork and frame are both in god condition as is the engine which shows the quality of restoration very well. Supplied with the rare bikini fairing and a triumph owners club certificate. A fabulous example of one of triumphs most sort after models.
