Triumph Junior Motorcycles 1914-1920s

Nicknamed the "Baby" ostensibly as it was the smallest of the range, some claimed the LW was thus named because it never went anywhere without a rattle.

The German Triumph Knirps (1919-1923) was very similar to the Coventry Triumph Junior.

The Two-stroke Model.

To turn to the two-stroke, this mount for 1915 has undergone very little change, and it is interesting to observe that the main alteration is in connection with equipment, which formed the subject of criticism in a recent issue of The Motor Cycle. 2¼ in. tyres have been standardised on this little machine, and a Brooks saddle of large size.

Except for a new type carburetter with top feed and separate chambers for the air and throttle slides, the 1915 two-stroke Triumph is unaltered. The bore and stroke of this mount are 64 x 70 mm.

The Motor Cycle, December 17th, 1914. p585.

The Triumph Junior (two-stroke) remains unaltered, and will sell at £63. The Motor Cycle, November 13th 1919
