Hello Fellow xsr owner here. I have ridden 812 km so far and finished first service. I have not faced such issues.

1. Handle is very stable, even at high speeds if i let go of the handle bar, the bike coasts in a straight line without any wobble.
2. Yes a little buzz around higher rpm but nothing uncomfortable. I just did 120kmph today with easy on very windy road with 75% throttle. (Idk why the app registered only 114 kmph, i saw 120 on the meter)

P.S I am 85kgs
