Introduced for the 1960 season, the Tiger 100A was the first sports version of Triumph's new unitary construction 500cc twin: the 5TA. A raised compression ratio and 'hotter' cams helped the Tiger to a top speed in the region of 90mph, while the retention of a single carburettor meant that fuel economy did not suffer unduly. The T100A was soon replaced by the T100SS and by the middle of the decade there was also an enduro-styled, 'off-road' alternative: the T100C. Readily distinguishable by its twin upswept exhausts, the single-carburettor T100C was sold at first only in the USA, but from late 1967 became available in the UK alongside the twin-carburettor T100T Daytona. The major change made to the UK-specification T100C was its 12-volt coil ignition, replacing the US version's battery-less energy transfer system.
As one can see, the machine offered here departs significantly from the generally accepted specification for a T100C, in particular the exhaust system and front disc brake. Also, although the frame/engine numbers match, the date prefixes do not; 'XE' indicates December 1970 as the manufacturing date for the engine, but 'R' was never included in BSA-Triumph's date-indicating numbering system (see Triumph Twins & Triples by Roy Bacon, page 182). The fact that 'TBK 109J' was not first registered until January 1997, and according to the accompanying V5 was 'previously registered and/or used prior to date of registration' only serves to cloud the issue still further.
