O.K. being an Aussie, I'd have to say;
1. Stephen Gall. (Australian version of Bob Hannah, took MX to the next level in the '70s/'80s
2. Damon Bradshaw.( Loved his attitude. Loved his "battles" with Matachivich, wonder what the AMA would have to say about the blatant take out moves of the '92 supercross series.)
3. Bad Brad Lackey. ( Too cool for school, still holds the title for the coolest helmet paint job- '82 flamejob)
