At last. Triumph have recalled my bike and will be fitting a complete set of shiny, new indicators. Hopefully this will solve the problem of the indicators falling off.
This was a known fault on some older models but the 2012 models were supposedly not affected. I have had four replaced in 10 months, so I will be very pleased if the fault has really been put right.
I suspect my dealer will be quite relieved, too. The smiles of welcome are starting to look a bit strained every time I arrive with bits of the bike dangling. Athough I have to say that every time it's happened the indicators have been replaced on the spot with no waiting at all and they has been proper grovelling (which I liked) from all the staff, so a big well done to Laguna Triumph in Ashford for not letting me down once.
Now, roll on next Tuesday so I can see if it's truly the end of the problem.
