Dirt Bike Madness

I remember downloading a demo probably 10 years ago or more. I think maybe it was just single player, but the game was named after, or favorites, some professional racer dirt bike. He had ragdoll physics where the guy would flail around all crazy at any time, it crashed. I did some research and Motocross Madness is like but I do not think that's it. The track demo has been out with a dirt track, green grass that surrounds it, and the hills and huge jumps.

He has a guy in his name.
