Ok....always a tough one. I know, it is impossible to diagnose by a post in a forum...but still trying 
Mostly in 4th and 5th gear, I hear kind of a rattling, metal on metal noise. When I go to neutral, it disappear. So it does not seems related to speed.
Seem to be related to transmission...it does not have a smooth sound. I have the R3 since 2 months and it is a 2015. Maybe it is normal sound...I would need to compare to another bike.
But if you know a lot about transmission, and I tell you it sounds a bit rough, mostly in 4th and 5th gear, would you have any idea of where I could start looking?
Thanks!
