What are the engine and frame numbers of a Triumph T100?
Note: All Grand Prix T100′s have letter ”R” suffix following engine and frame numbers. TR5 models had separate number series; engines from 101001 to 106424, frames from TC11001-T to TC13107-T. Starting in 1950 frame and engine numbers were matching.
When did the Triumph 500cc model come out?
Although Triumph only produced the model for two model years (1973/4), there are two conditions of frame. Both are good but the later condition has more bracing around the frame loops in the swing arm area and so should be stiffer. I believe some cracking in this area was experienced with the earlier frame and resulted in these modifications.
Where are the engine numbers on a triumph?
Vintage Triumph motorcycle engine numbers are stamped into the case just below the cylinder on the primary side. Frame numbers are stamped into the frame on the headstock also on the same side. Crooked stampings and unequal depth are common. Frame numbers match the engine number after 1950, but may not have the model designation, only the numbers.

When did the Triumph engine and frame change?
This is a comprehensive table of Triumph model serial numbers from 1950 to 1983. Engine and frame numbers should match, as they did when the motorcycle was new from the Triumph factory. If they do not match, that means the frame or engine was replaced sometime in it’s history.
