the Yamaha knob setup is pretty lousy but I’ve never had any come loose, I messed with the adjustments a few times when I first got it but haven’t touched them since.I constantly have to check the Yamaha adjustment knobs because they do com loose
my 2018 seems quite a bit smoother than the 2013, I suspect that’s mostly because of the rubber dampened handlebars.Have my windshield in a good spot so no need to change, but this bike seems to vibrate some. More than my 2012 tenere . Not sure why
