Since you pidgeon-holed us into "GOOD" I'd say some documentaries are in order. That would be, of course,
On Any Sunday (Bruce Brown's Legendary work)
FAST (Grand Prix)
FASTER (Grand Prix)
The Tornado, The Doctor, and the Kentucky Kid. (Grand Prix)
Although the last 3 are racing documentaries, they are spectacular to watch, especially the sliding around on the big 4 strokes in the last one.
There is also Viva Knievel, which is a bit cheesy, and a Documentary on the real man that includes his most famous jumps.
Nobody mentioned The Great Escape, which was not specific to bikes, but has Steve McQueen, who is also prominent in On Any Sunday, and Racer/Stuntman Bud Aikens' jump over the fence to escape the Germans is iconic.
Also from the "B" reel, check out C.C. Rider. Joe Namath trying to go racing, yet riding with a "club".
Oh yea, racing started a lot of "clubs", and post race partying turned into no race, all party.
