640A
I have an 06 and love it.
Mark (Earthmover) has an 04 I think and we both regularly trail ride them. I also do a few races (Rally's) on it.
Not done any real road distance on it but taking it to Portugal end of April for a few weeks - watch this space!
With my off-road gearing, it's still good for a 70 mph cruise and tops out at about 90 so road work shouldn't be a prob.
I think you will find that some will vibrate a lot more than others - luck of the draw. I don't find mine a problem but as I said, not done many big road trips as yet.
Overall, nice bike, looks 'The Dogs' in my opinion and is a good all-rounder. Go on, have a go......
Cheers, Rick.
