1961 Triumph 490cc 5TA Speed Twin
Registration no. YNF 268
Frame no. 17988
Engine no. 49298
Introduced in September 1958, the 5TA Speed Twin was the second of Triumph's new family of unitary construction vertical twins, joining the 350cc Twenty One/3TA launched the previous year. The 500 closely followed the lines of its 350 predecessor, there being little to distinguish it mechanically apart from a larger bore, raised gearing and larger-section rear tyre. The controversial 'bathtub' rear enclosure introduced on the Twenty-One was retained and the Speed Twin came finished in the model's traditional Amaranth Red.
This much-modified 5TA Speed Twin comes with old-style continuation logbook listing the current, non-original engine (which dates from 1966) as fitted to the machine at time of issue in 1974. The current vendor's father is listed as '1st Change'. Additional paperwork consists of old/current Swansea V5/V5C documents.
