When Jack is riding what appears to be a 2003-2005 YZ250/450, when he goes to kick it over, the film is backwards as the kick starter and exhaust are on the left side, and even more obvious, the name on the side reads AHAMAY instead of YAMAHA. From that point on, the film is correct and the kick starter and exhaust are where they should be, on the right-hand side.Throughout the scene, there are standard motocross sized wheels, 21" front and 18" rear with knobbies. During the final scenes on the bike, it gets a set of 17" supermoto wheels and tires.
