1978 Triumph T140E

By 1978, the Meriden workers’ cooperative was refining the Triumph Bonneville into its most usable form, and this T140E is a stellar example of that late-seventies peak. Showing just 19,000 miles, this machine strikes the perfect balance between a preserved survivor and a bike that "runs beautifully." For the purist, it checks the most important boxes: it comes with a clean title and is a fully numbers-matching machine.

Mechanically, this Bonneville is sorted and street-ready. At the heart of the T140E is the 744cc air-cooled parallel-twin, an engine that delivers the iconic British thump with a more civilized 49 bhp. Whether you’re looking for a weekend canyon carver or a centerpiece for a British bike collection, this T140E offers the timeless Meriden silhouette without the mechanical headaches.
