The Triumph Boss 350 is a highly rare and unique classic motorcycle built not by the famous British manufacturer, but by its German sibling company, Triumph Werke Nürnberg (TWN). The year 1957 marked the final year of production for this flagship model, as the manufacturer shifted focus away from motorcycles due to a changing post-war market.

The defining characteristic of the Boss 350 is its two-stroke ‘split-single’ (or twin-piston) engine.

This is a very rare opportunity to own what is a truly outstanding bike. These do not come to market very often so do not miss out!
