Triumph Frame Numbers

Model Years for specific frame number ranges. Manufacture of a model year usually begins about half-way through the previous year (e.g. a 1963 Bonneville could have been built in November 1962).

All production dates (after the number range) are approximate.

1937 to 1949

Frame and engine numbers did not match. Frame numbers were not sequential. Engine numbers were prefixed with the year then the model (e.g. 8-T-1234).

1969 to 1980

Frame and engine numbers matched. Month of Production and Model Year prefixes now used. The model code was also included at the start or end for all machines.

Letters A, B, C, D, E, G, H, J, K, N, P, X represented the month of manufacture January to December (first letter). The same letters also represented the Model Year starting with C for 1969 through to B for 1980 (second letter). There wasn't always a definite cut-off between model year numbers and in some cases earlier or later numbers were used out of sequence. T150Vs used a different series.

Hinckley Era

Hinckley started using the standardised ISO 3779 VIN numbering system, however there were two versions of that standard in use by Hinckley from the start - USA and European. The USA variant is used mainly in the Americas with the European variant being used for the rest of the world.

Engine numbers are just that, numbers, and don't match the VIN.

For the USA variant the Model Year character is in position 10 (e.g. SMT371CA2SJ020929 where S = 1995).

For the European variant the Model Year character is in position 11 (e.g. SMTTC354CRS020961 where S = 1995).

For both variants SMT indicates UK and Triumph. The next 5 characters are the model range and type (different codes in either variant). The 9th character is a checksum in the USA variant but relates to the engine configuration in the European variant. The 10th character in the European variant is the final drive ratio. The 11th character in the USA variant is the factory code (J = Jacknell Road Hinckley, T = Thailand, M = Manaus Brazil, D = Manesar Dehli India). The last 6 characters are the sequential frame number.
