Cool as Ice - you have to laugh, it's Vanilla Ice!
Mad Max - had some good scenes i think, it's a little fuzzy
The Great Escape
if you want something a little cheesy, check out "How to Stuff a Wild Bikini"
Grindhouse
I think maybe the 3rd Resident Evil,
Ghost Rider (though i wouldn't recommend it)
i think there was some stunt biking in Fantastic 4
Ultraviolet had some in there
Something a little more special interest is "Long Way Down". It is a mini-series documenting Ewan McGregor and his best mate traveling round the world on motorbikes.
I ride a bike as well. A Victory Kingpin Tour. I'd agree with most of the recommendations so far, but would add my personal favorite "The World's Fastest Indian," and believe it or not, "Wild Hogs."
Oh yeah, loved the World's Fastest Indian. Anthony Hopkins plays Burt Munro who set a land speed record at the Bonneville Salt flats in the '60s on a custom built circa 1920's Indian motorcycle. Great movie, forgot about that one.
