I have a feeling that this thing will be super tall with the full XR treatment. A little extra height would be ok, but those forks are whole 1 and a half inch longer than stock XL, that and the shock is something like an inch longer. That's quite the jack up. If I was a trail rider sure, but I'm an urban dweller and I don't know about riding around town on what would be something like a 36" seat height.
I'd be able to see much further above traffic though. I could coordinate traffic lights from miles off into the distance.
