Trying to find a movie

There was a movie i saw on speed a while back, and i just caught the end of it where the main character crashes at the end of the race after winning and the bike explodes with him laying there. After that the credits roll. I just thought is was such a funny obscure ending to a movie that i wanted it to see it again. Not that the thought of someone crashing on a bike is funny but i laughed my a** off when i saw it because it was so unexpected and over the top.
