From memory, faint though it might be, Triumph did a T100 kit in 1953 that turned the then-current rigid all aluminium engined T100 into the T100C – a Clubman’s bike that could be raced competitively in the 500cc class. From memory it contained a splayed inlet head so that the twin Amal carburetors that came with the kit could be fitted. Also in the wooden box were two E3134 cams, a close ratio gear cluster and other bits to enable racing. In 1955 a mate of mine bought a 1954 swinging arm Tiger 100 that had this kit fitted. It also had a small bore exhaust system and Burgess straight through mufflers. With the close ratio gears it was a pig to ride in traffic as the clutch had to be slipped up to 30mph, after that it was fine. It was faster than the BSA B34 Gold Star, the other bike of choice at the time, but did not handle as well! I believe Triumph had a few kitse
left over in the shed at the back of the factory and sourced the Baby Bonnie (see Cob’s Column, OBA
58) bits from there.

A reasonable conjecture, although those race kit bits must have been in the shed behind the Triumph factory for a long time, as the race kit was last listed in 1952. For 1953, the Tiger 100C was offered, being effectively a catalogued model in race kit specification, with twin carburetors, racing camshafts, big fuel tank and so on. Options included the high compression pistons and closeratio gears previously offered with the kit.
