Flash back to 1997. The X Games were not even a thought, and Brian Deegan was racing 125 Supercross on Team Moto XXX as a privateer. It was the Los Angeles Supercross at the Coliseum and Deegan rode to his first (and only) win in the 125 class. Upon crossing the finish line, Deegan ghost rode his RM across for the win in the most punk rock maneuver in Supercross history!
I wasn't there, but I sure as hell wish I was to see that in person. EJ posted an old Cycle News article about the infamous ghost ride over at Alpinestars.com that will make you feel like you were there...good stuff and worth a read.
