Ok, I'll take the bait. In 2008 I had a 2001 XT225 that I had bought to introduce my nephew into the sport. A co-worker with a 2007 F650GS Dakar expressed an interest in going with me to the Desert 100 here in WA. My friend was not long out of college and had competed in street trials which is bicycles but very demanding. Anyway to make a long story short he did just fine completing both laps while others on far superior bikes did not.
If you're not actually a troll the yes, it can/has been done. The bike is only as good as the person who rides it and a good bike doesn't make a good rider
