Not just the rails but the heat shields too, I had to weld the ones on Wendys bike multiple times. My welds never broke but they would break again in a different spot.


That sounds as if the new breaks are occurring at what is called the "heat affected zone boundary". Weld metal grain is all askew, similar to the metal in a casting, the rod of the seat rail has grain like wood in the direction it was drawn during manufacture. Where the grain changes is a stress riser. A normalizing heat treat after the initial build process would probably cure this common problem and this complaint/posting would never even exist. This is a build flaw that is ultimately Triumphs fault and they should replace them until they get a clue and review/change the process.
