Triumph 1922 Model H 500cc 1 cyl sv



Triumph   1922    549 cc   Model H   frame 330245          engine 69756  MRX

The model H was announced late in 1914 as a logical development of the famous veteran        “ Trusty”. But it  wasn’t just  a 1914 model with a countershaft gearbox: the engine differed from the veteran engine in various ways. It had a single cam wheel  with 2 cams instead of separate cam wheels for the inlet and exhaust valve. 
The casting for the cylinder was entirely new, the valve head diameter was enlarged by  ¼ inch and the valves were spaced further apart. 
A great improvement over the 1914 style 3-speed hub was the Sturmey Archer countershaft gearbox. 
The primary chain drive was enclosed by a neat aluminium cover; secondary drive was by belt.
1922 and 1923 Models had a redesigned front mudguard supported by large “U” shaped front stays, the open section of the “U” facing forwards. 
These stays were called “rain deflectors” by Triumph and they were a patented attempt to channel rainwater away from the rider’s legs.
The model H was a very successful model: some 30,000 were supplied to the  British and allied forces during the War; total production till 1923 came to a grand total of 57,000.
This finely restored,  venerable H is  utterly reliable, full of character  and a pleasure to ride; what more can you want from a vintage machine?
