General: We use a plain dash  to seperate part number fields. If you are having no result with the search engine, try using just the last four numbers (max) or just the numbers after an alphabetic character. Note that in our price list there are sometimes options for the original item & these are designated by the letter "A" following the part number, e.g. 060632A. Stainless parts are followed by the suffix "SS". Obsolete part numbers, where the description says "USE....", go to that new number for the price & use the new number when ordering. If you can't find the part you're after please enquire, we may still be able to help.

Triumph Part Number Conversion: Important information for pre 1973 machines  in 1973 Triumph introduced a numerical part numbering system which superseded the old alphanumeric system. For these earlier models the following information will help to find the new number in our price list. Prefix letters have been converted to numeric prefixes, as shown in the table opposite. We use a plain dash  to seperate part number fields. If you are having no result with the search engine, try using just the last four numbers (max) or just the numbers after an alphabetic character.

Alphanumeric converts to Numeric 
Example 
Dxxxx converts to 60xxxx 
D4250 to 604250 
Exxxx converts to 70xxxx 
E4576 to 704576 
Exxxxx converts to 71xxxx 
E12599 to 712599 
Fxxxx converts to 82xxxx 
F9356 to 829356 
Fxxxxx converts to 83xxxx 
F13245 to 833245

Norton Part Numbers: The preCommando part number system can be tricky & it may be best to use the alphabetical section of the price list. Most Commando parts begin with either 06XXXX or 04XXXX & are then followed by a further 4 digits, e.g. 063371.We use a plain dash  to seperate part number fields. If you are having no result with the search engine, try using just the last four numbers (max) or just the numbers after an alphabetic character.

BSA Part Numbers: From the mid sixties onwards BSA adopted a standard numbering sequence which follows the pattern of 2 digits, a dash, then followed by a further 4 digits, e.g. 712790. Prior to this BSA used two other part number formats, the early system used less than six digits & requires zero's to added. The later system then preceded the original number with additional codes. With these numbers only the last six digits are used. We use a plain dash  to seperate part number fields. If you are having no result with the search engine, try using just the last four numbers (max) or just the numbers after an alphabetic character.

Numbers using LESS than 6 digits: 22582 becomes 022582, 15152 becomes 150152, 279 becomes 020079 
Numbers using MORE than 6 digits: 116422631 becomes 422631 
Fortunately these problems don't exist in too many of the BSA books, but if you can't figure it out let us know; remember too that just when BSA got it all sorted out they went broke!
