The earliest Triumph motorcycle model numbers and frame numbers were recorded in 1937. The numbering scheme for both the model numbers and the frame numbers was changed a total of four times before 1969. The numbering scheme was standardised in 1969 and continued through 1980. It is important to know your exact model number to ensure that you order the correct parts for your Triumph motorcycle.
