Looking at Triumph Bar End Mirrors? Get them soon, while stocks last, cos the 1050 2011-2016, are now obsolete. I had a look last night and you can still get them from limited supplies. Part no. A9638060.
The actual bar end mirror itself is part number A9630038 which is still available, I think its only the kit that is now obsolete, but I'm pretty sure the kit for the Street Triple is identical: https://www.worldoftriumph.com/part...triumphmc/modelid/610102/block/100061723-0-2/
They went on sale just before being made obsolete, and I was fortunate enough to buy a pair of the kits for my Street Triple at about £40 each, I liked them so much I got a pair of the Speed Triple mirrors as spares when I saw those on sale also
