My Roadster has 34000kms now, the vibration still continues, I think is a little worse, comes in at around 2200RPM, disappears at 2400RPM then comes back at 2700RPM on acceleration and decelerations. Can feel it through the handle bars and foot pegs, disappears when the clutch is very slightly pulled on.
My mate had a 2008 classic, it annoyed him so much he sold the bike, the local Triumph shop tried twice to fix it but could not. I rode two demo Roadsters before buying mine and both had the same condition.
I have reported it to Triumph Australia twice.
I know one thing, it’s so smooth when the clutch is pullled in slightly. It will be a great day when the solution is found.
