Some of my favorites (not sure whats available online...)
On Any Sunday (both the original, and the one produced by Red Bull, mostly because they profile Speedway at Costa Mesa)
The Faster series (back when Rossi was still the dominant MotoGP rider)
The Doctor, the Tornado and the Kentucky Kid (documentary on the season that Hayden won the MotoGP championship)
Dust to Glory (Baja 1000 coverage the year Mouse McCoy rode it solo)
And for a movie based on a true story, nothing comes close to The World's Fastest Indian
