I wouldn't be in a rush to ride with others just yet. Pushing too hard will lead to trouble, or worse, even if you aren't pushing too hard, one of them could do something stupid. I had that happen to me at last year's Death Valley event, when some bonehead passed me in a rocky section, after the ride leader specifically said NO PASSING, which caused me to lose it and crash. To this day my left elbow still hurts like hell at times.
BTW, I finally got to see a CRF250L in person yesterday. Man that really is a pretty bike! It looks more like a sculpture than a bike, it's so pretty. If I wasn't already 100% satisfied with my KLX250S, I'd be jealous. :)
