Triumph 1920 “LW” “Junior” 225 cc two stroke frame # 600098 engine # 5374 4

The Model LW, also known as the Junior, and nicknamed the ‘Baby’ for it was the baby of Triumph’s models, broke new ground for Triumph as they had not produced a two-stroke engine before. However, Triumph ‘got it right’ and with its low weight, ease of (paddle) starting and the low saddle height the model gained immediate popularity amongst District Nurses, Ministers of the Church, and schoolboys with wealthy parents! (The legal minimum riding age in those days was fourteen.)

Initially the Model LW engine was of 225cc capacity, and although it had a diminutive 2-speed gearbox there was no clutch or kick-start.
(A clutchless gearchange was achieved by a swift opening of the engine’s pressure relief valve.)
For its last three years the engine capacity was increased to 250cc and a clutch and kickstart were added.
Production continued during the 1914-18 war years for the Model LW was also used on war service.
Manufacturing competitors and owners of products of those other motor cycle manufacturers, claimed that the Model LW was nicknamed ‘The Baby’ because it never went anywhere without its rattle!

Weight of this very tractable machine is around 60 kg and she has a cruising speed of about 55km.
The machine we offer was first registered in Lincoln and she has been part of a museum collection for many years, which might explain her remarkable state of preservation.
Most of the original enamel and nickel work is still present.
