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 subsequently renamed '3TA'. With only 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'. Dating from circa 1958 but fitted with a slightly later engine, this Twenty One is described by the private vendor as in generally good condition. The machine is offered with MoT/tax to October 2013 and Swansea V5 document.
