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.

Hint: Recommended bike:
The best bike is the first one you get, because you will get offers for bike upgrades that increase its stats. However if you choose to switch bike companies, the upgrades are lost. Stay with the first bike and by the end you will get an awesome bike. You can accept all other offers though.

Glitch: Everglades: Jump over 600 feet:
From your starting point on the dock, back up slightly and look to your left. Ride over to the set of jumps that are at the other end of the barges. Once in the area, ride over the jumps to your left until you reach the jump that is directly left of a palm tree. Past this jump are two landing slopes; one that is directly in front of the jump next to the palm tree, and one that is behind it and to the left. Ride over to the second slope and face the right hand corner/side area of it. Continuously ride into this area, trying to push your way through it. With some speed and the proper placement, you should be able to ride through the corner of the slope and ''fall'' through the ground, eventually re-spawning back onto the dock where you started. During this ''fall'', you will also be able to string together as many tricks as you wish for an insanely huge multiplier without the fear of crashing; when you re-spawn back onto the dock, the game still acts as if you are in the air, Note: Be careful with the gas and brake/reverse, as the game also acts as though you are on the ground as well. When you are done with your multiplier, speed off into the level as usual. If done correctly, when your jump distance meter appears it should read more than six hundred feet. Note: Repeated use of this glitch to increase your multipliers may cause the game to crash. Make sure to save your place immediately after you have achieved your new jump distance. As with any glitch, use it at your own risk.

Glitch: Everglades: Fly:
At the beginning of the level, go completely straight off the dock. You will go between a small house-type building and a palm tree. Keep going straight and make a small right turn. You will see a white trailer. In the back of the trailer is a small propane tank. Next to it are two barrels. There is a barrel to the right of the propane, and a second one in front of that. Face your bike towards the propane, then slowly go towards the first barrel. Align your bike's tire towards the first barrel until you cannot go anymore without falling back. Hold the gas and you will eventually fly in a different direction.

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.
