I'm transitioning from a CRF250 to a used CR250. The CR appears to be a low hour, un-molested, original bike. I've run it a couple of times and am quite amazed at the vibration. It's been my understanding that 2-strokes vibrate more than 4-strokes, but this is quite impressive; at very low RPM, it's like a Lazy Boy recliner set on very intense massage mode. I've ridden a couple of 250 2-strokes in the past, but I don't recall how much they vibrated. Does this sound like a normal level of vibration?
