Rickard Nebrer has a wonderful site dedicated to the BSA B50.

I found the site through a google search and it was also recommended by the the folks on the Britbike forum (another great source of info).

Although a BSA site, it covers the B25, which the Triumph basically is, the CD that Rickard sells gives heaps of info, Parts Catalogue’s, owners manuals, tech tips etc, under the extra’s was a complete set of T25SS manuals.

If you have a BSA or equivalent Triumph vistit his site, you’ll be glad you did.
