.060 Over
I have a 2016 R3R and you just described what I have been hearing and feeling on my left foot peg. I keep hearing and noticing something from my foot peg and look down to see if something is loose. I figured it was internal but could not figure it out. I have 3000 miles on it now, in the middle of a road trip. Its going in this winter for Triumph to fix it, it is all stock and I treat it well, let them try to say its not their mistake!!! Funny that is when the vibration started also!
@TimR3 I'm sorry to hear that you are having problems
I would advise you not to ride it until it has been repaired. From first hearing and feeling the 2nd gear noise/vibration, it only took a few miles before (in my case) 4th gear shattered. I was very lucky, as I was close to home and pulling upto a stop, if I had been on the motorway, it could have been fatal. @mr hunt had his gearbox jam up altogether
It feels so much better now, much smoother and quieter.
It's lasted 500 miles, so far, with the oil and filter changed yesterday

GOOD LUCK! Please let us know how you get on!
