From the review it seems that it more the worst of both worlds than the best of both worlds. At least moderately.
Hmm so he seems to be complaining that the long travel suspension is too plush and the 21" wheel makes it too stable. On the other hand would he be complaining that it didn't have enough suspension travel and a small front wheel made it twitchy off-road?
Don't know about the vibes but no one else complains about vibes on the other F800 bikes. I wonder if his bike had enough break in miles on it?
