The David Plant Collection, 1959 Triumph 350cc Twenty-One

The David Plant Collection
1959 Triumph 350cc Twenty-One
Registration no. BVH 668A
Frame no. H7477
Engine no. 3TA H7477

Triumph re-entered the '350' class in 1957 with the introduction of the 'Twenty-One'. Its arrival ushering in Triumph's unitary construction era, the model took its name from the engine's approximate cubic capacity in inches. Readily distinguishable by its Shell Blue metallic finish and 'bathtub' rear enclosure - a feature later applied to Triumph's larger models - the newcomer was later renamed '3TA'. 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.

Acquired by the current vendor in 199, the Twenty-One offered here appears to be an older restoration that has started to deteriorate in places and will require recommissioning before further use. The odometer reading at time of cataloguing was 8,479 miles. The machine is offered with old/current V5/V5C documents and two instruction manuals. The engine turns over.

Following a period of inactivity, this motorcycle will require recommissioning and/or restoration to a greater or lesser extent before returning to the road and thus is sold strictly as viewed. Prospective purchasers should satisfy themselves with regard to this motorcycle's completeness, history, authenticity, originality and mechanical condition prior to bidding.
