Yes, the XR will test my self-control over the next week or so, that's for sure. There are some high-frequency vibes in the bars but nothing to really complain about. I heard they added some bushes to the bar mounts to sort that issue.
As for the bike overall, I guess it's simply a case of horses for courses. For me, this bike would probably prove too frantic as I prefer a more relaxed ride, but I can certainly see the attraction.
