Super speed:
Enter JIH345 as a password from the options menu. The only way to disable this code is to reset the game; make sure to save your progress before doing so. Also, this code will cause your bike's handling to decrease considerably at higher speeds, and you will be more prone to bottoming out when landing. Be careful if you plan on using it during your career.

Glitch: Rock Quarry: Jump over 900 feet:
Enable the "Super speed" code. Play at the free ride area "Rock Quarry" When you start, do a 180 and go down the big ledge towards the container jump. Clear it, then hold it pinned. As you approach the excavator, jump and keep holding it pinned. Jump it as close to the wall as possible. When you are airborne, whip it to the right (towards the wall) and hold it. You should fly over the wall and into a glitch where everything turns white. You will fall for a while, then respawn on the ground with the game stating that you have jumped up to 1,000 feet (usually in the 900 feet range).

Glitch: The Compound: Jump up to 2,000 feet:
Do not enable any cheat codes before you attempt this glitch. Play at "The Compound" in the Free Ride category. When you start, take a small left turn and go towards a light colored paved road. Ride straight down this road and you will pass a black tour bus. After you pass the bus you will be on a dirt road and then see a red house-shaped object marked "199". Immediately after you go past this object, take a hard right turn. You will be on a different road. Continue down this road and you will be on a lighter colored road and see a ramp that marked "MTX Mototrax". Just after you pass the ramp take a hard right turn and go straight down another road. You will see another ramp marked "MTX Mototrax". Jump off this jump. It will lead you to a different road. After you have traveled down the road you will see another ramp that reads "MTX Mototrax". Go directly down the center of the ramp using full boost and traveling at least 60 mph. Just after you leave the ramp continue holding the gas and press Left Analog-stick Right so that your bike is level. You will go through the side of a huge rock and the screen will turn blue. After you "fall through the sky" you will respawn at the beginning of the level. That game will state that you jumped somewhere near 2,000 feet.
