Tiger Cub (T20) 1954/55
Picture
Exactly one year after the introduction of the new Terrier model at the 1952 Earls Court Show, Triumph once again stunned show goers, this time with a new enlarged version. The Tiger Cub had arrived and as was common Triumph practice with its larger models (Tiger 100, Tiger 110), it was billed as the 'sports' or 'Tiger' version of the smaller engined Terrier.
 
Resplendent in Triumph's Shell Blue Sheen and black, a larger 199cc engine had been placed into a Terrier rolling chassis fitted with larger 3.00 x 19 tyres, mudguards with a raised central rib, a black-faced 80mph speedometer and different gear indicator in the nacelle.
Picture
As standard the new Tiger Cub had a dual seat and high-level exhaust (although a single seat and low level exhaust was specified as an option). The new engine producing a very handy 25% more power than the Terrier's smaller unit.
