Antti Pendikainen uses his motocross bike to BASE jump off a ramp, reaching 131feet (40m) in the air before plummeting into a river below. The parachute seems to open late and doesn't aid in his landing much.
What an incredible stunt! In the full versions of the video you can see Antti talking about the jump beforehand and they do get the bike out of the water afterward.
