Cruising at the 30 mph, I have difficulty identifying spatial relation of objects in my OEM mirrors due to the amount that they are vibrating. At WOT, approaching the rev limiter, the bike is like riding an earthquake.... I can't agree with the statement that the XB's are about on par with other bikes in terms of vibration at idle or on the throttle. The XB has many positives IMO, but vibration dampening is not one of them.
