Baby Bon­nie?

Old Bike Australasia - - LETTERS TO THE EDITOR -

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.
