With over 8,000+ mi on my '09, I went through the same all sorts of quirky stuff (vibrations, squeaks, creaks, rattles,etc) during the first 7000+ miles or so. before getting everything shimmed. Now my '09 is silky smooth and quiet It is smoother than my former BMW R1200R with similar RPM to MPH ratio. The BMW has more torque and power as it is twice the size, but in comfort -this would have to go to the '09 B650EX, but darn frustrating shimming out all the quirks. '09 B650 more comfortable both on streets and highway cruising at this time than ever was my R1200.My '13 has a noticeable vibration between 2500-3000rpm under light acceleration and then smooths out over the rest of the rpm range. A little more noticeable during the very first mile or so in the morning. If I accelerate a little more briskly I don't notice as the tach flys by that 500 rpm range pretty quickly. Like I said, the rest of the ride is as smooth as glass....My '09 went through all sorts of quirky stuff (vibrations, squeaks, creaks, rattles,etc) during the first 5000 miles or so. ...Overall ride seems a little smoother than the '09.
