While I have a 2013 roadster, not touring, It had factory Metzlers with about 3,200 miles on the bike. I noticed the same premature washout when pushing in the turns. Kind of unsettling, to say the least. I changed to Avon front and Excedra Max rear and was utterly shocked at the difference! I really couldn't believe it. I kept jumping on it and heading for the twisties in the foothills because I felt like I had a brand new motorcycle. I just can't imagine the bureaucratic $hit that allows Triumph to put Metzlers on a rocket? I would think they'd have changed by now just from a liability standpoint.
Here we go again......another "tire thread"
