The Triumph Tiger Cub was a 200 cc single-cylinder British motorcycle made by Triumph Motorcycles at their Meriden factory. Based on the ''Triumph T15 Terrier'' 150 cc, itself a surprise announcement just before the 1952 show,〔Motor Cycle, 30 July 1964. ''Readers report on Triumph Tiger Cub''. "''The Cub's ancestry dates back almost 12 years—to November 1952 when Triumphs introduced a "stimulating, last minute eve-of-show surprise", the 149 cc Terrier. This was followed, a year later, by the first of the Tiger Cubs, with a 199 cc engine in the Terrier's plunger-sprung frame. Here we are dealing only with Cubs from 1957 onwards, when the pivoted-fork model was introduced.''"
