Triumph single cylinder motorcycle model engine & frame numbers 1935 & 1936

Engine & frame numbers for Triumph single cylinder vintage motorcycles including the following models, U2, Tiger 70, Tiger 80 and Tiger 90.

I have compiled a series of tables to show the generally accepted information on the engine and frame numbers for Triumph motorcycles. This table shows data specifically for the veteran Triumph single cylinder motorcycles for 1935 and 1936

Single cylinder models, 1935 / 6

Year(s) Models Engine numbers Frame numbers
1935 Model U2/1 Engine prefix IL5 frame L
1936 Tiger-70 Engine prefix T-1 L6 frame SI
1936 Tiger-80 Engine prefix T-2T6 frame SI
1936 Tiger-90 Engine prefix T-5S6 frame SII

Note: 1935 and 1936 Models same as 1934, only final number or prefix changes to ‘5’ for 1935 and ‘6’ for 1936
