Watching mission impossible on the telly and the bikes don't sound like they're supposed to. Then the tires are different in shots on the street, street tires in the road shots and knobbies in the dirt..
When the bikes do a jump scene it looks like a made up dirt bike
While I am at it when they have dirt bikes sounding like 4 cyl. street bikes or four strokes and why do the tires make squeeling sounds when they burnout in the dirt.
And 10 guys with fully automatic weapons always looses to one guy with a pistol that never runs out of ammo....
