The 1957 Triumph Tiger Cub T 20
1957 Triumph Tiger Cub T 20 sits at the entry point of Triumph's postwar range, the small-bore machine built for riders who wanted a real motorcycle without the weight or cost of the bigger twins. This is a lightweight, single-cylinder bike designed for commuting, learner riders, and anyone who valued simplicity over speed. The Amal monobloc carburettor setup reflects the era's straightforward approach to engine tuning, easy enough for an owner to service themselves with basic tools. Around town or on secondary roads, it feels nimble and manageable rather than quick, rewarding riders who enjoy the mechanical experience over outright performance. The 1957 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 1956 example should focus on mileage, service history, and condition rather than spec differences. Today's buyers tend to be vintage motorcycle enthusiasts drawn to accessible, affordable classics rather than blue-chip investment pieces, often riders stepping down from larger modern bikes who want something simpler to maintain. The 1957 Triumph Tiger Cub T 20 also appeals to restorers looking for a manageable first project, given its uncomplicated single-cylinder layout and modest parts requirements.
