Yeh sorry about that, just read triumph and assumed it was for bikes, oh how i was wrong, my mistake.

Would anyone be willing to do me the favor of explaining to me exactly what it is these numbers and letter represent? Any and all help would be greatly appreciated. Also, if you have a source for such said information I'd gladly be willing to check that out aswell. Thanks ahead of time, have a fantastic day. Cheers from across the pond.
