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?
