A landmark machine in the development of the motorcycle in Britain, Triumph's Model P debuted at the 1924 Motor Cycle Show. A no-frills, sidevalve-engined model, the newcomer was priced at £42 17s 6d, at which level it undercut every other 500cc machine then on sale in the UK. The first batch manufactured was not without its faults, but once these had been sorted out the Model P was a runaway success. Output from Triumph's Priory Street works was soon running at an astonishing 1,000 machines per week, and the Model P's arrival undoubtedly hastened the demise of many a minor manufacturer. Production continued until the decade's end, by which time the Model P had spawned a number of derivatives - models N, Q and QA - and lost penny-pinching features such as its guide-less valves and bicycle-type front brake.

This Model P is offered as an incomplete restoration project and is sold strictly as viewed. There are no documents with this Lot.
