I thought the same but...that countershaft bearing is huge and I bet it almost can't blow up unless it gets really, really bad. Wheel bearings are new OE, I pulled in the clutch at speed and let it idle with the bike coasting at freeway speed - no vibration. Brakes are also relatively new and they are not dragging. Wheels are correct as are rotors and rubber.
It's really hard to describe/diagnose over the Internet - if you drove it you would probably think along the same lines. Easiest way to describe it would be that it's a vibration from the engine, you can feel it through the pegs and bars, and it appears to be directly related to coast/drive loads on the throttle. Ie, if it's sitting still in the garage and you rev it, it won't do it. It has to be under drivetrain load.
