Balance and pitch:
Keeping your balance and adjusting the pitch of your bike while in the air is the key to success. There are two ways to do this. You can either move your rider fore and aft, or you can work the gas and brakes to spin or stop the rear tire.
Shorcuts:
There’s more than one way through most courses. When outdoors, explore the foliage. When indoors, set up your bike and modify your line to take an entire section of bumpy roadway in a single jump.
Blast off a mountain glitch:
Ride to the very edge of the screen until you see a big mountain. Try to ride up the mountain. If you make it three-quarters of the way up, press [Tab] to warp to the top. If you land on top, keep driving (do not drive off the mountain) and you will be blasted far off screen.
Stick man and bike glitch:
In Enduro, do not edit your bike then choose a level. You will end up as a strange man with a bike made of sticks. Note: This may not work all the time.
Invisible man glitch:
In any Stunt Quarry with a lot of shrubs, press [F11] and lower the “Overall Graphics Quality” to zero. Hide in a shrub, and you will be invisible.
Whistling noise glitch:
Go on Stunt Event and go to the edge and up the cliff. Keep going until you start flying away. Quickly press [Tab] to reset yourself before you go over the edge. After a few seconds, you will hear the whistling noise that occurs when flying normally.
