That story the illustrates why motocross is the best motorsport in the world. Every other form of motorsport relies on spending cubic dollars to be competitive.
Your average modern racer might disagree, but you don't need bling, titanium and tatoos to go fast. Big B@lls and skill will do it every time.
We had a similar rider in the Thumper Nats 10 years or so back. He would turn up on a bog stock KLX250 [and a ratty on at that] and run with fast guys on their much modified fourstrokes. It was great to watch. Long live the underdog!!!
