Hint: Quick start:
When the timer starts, hold the wheelie and the turbo button. When you start, begin to pull in front of your opponents. Note: If you go down a hill or touch another person or the side, you will crash. You will also crash if you go above 50 mph.

Select a mode that is two player compatible. When the race starts, do a wheelie until you fall off your bike. You will then start the race in first place. Note: This only works on some tracks.

Hint: Turbo boost:
When you are just about ready to go off a jump, press Analog-stick Down and press Turbo. If done correctly, you should hear a noise. You can do this an unlimited number of times.

Hint. Faster, sharper, and quicker U-turns:
Hold Brake and use the "sharp turn" technique. Hold R while turning. This works well if you need to slow down and turn quicker and faster on an oncoming U-turn.

Hint: Sharper air turns:
Attempt an air turn, and while turning in air, hold Brake. Alternately, use the "sharp turn" trick while in the air. This works best if you have jumped a little too far on an oncoming U-turn, and you need to turn sharply in the air.

Hint: More air:
Hold R + Left or Right off a jump. You will get a lot more air and additional time to land.
Information in this section was contributed by Chris Torres.

Hint: High and quick jumping:
Pop a wheelie, then hold Turbo. Release Turbo just before the top of the jump, then tap Turbo at the top while still maintaining the wheelie. This works well if you have crashed just before a steep jump and you need to speed up to complete the jump. For the highest jumping in the game, use this trick on "The Gravel Pit".

Ride around after race:
Hold Z + A to pull a wheelie in training mode just before you cross the finish line. Release Z to slow down, then fall off the bike. You can now ride around the entire track.

Hint: Temporary invincibility:
Pop a wheelie immediately after the race begins and fall off your bike. The CPU will reset your biker, giving you temporary invincibility.

Hint: Avoid overheating:
You will begin to overheat while using turbo when racing. To get your temperature gauge back down, just wreck one of the other racers by clipping their front tire with your back tire. Your gauge will go down to nothing.

Hint: Custom course win:
Place a landing ramp in the middle of the track, with no jump in front of it so that the steep slant of the landing ramp functions as a jump. Each time you pass the ramp, at least one of the CPU riders will fall off their bike. Tricks and air turns are unhindered.

Hint: Crowd takes pictures:
To watch the crowd take pictures go off a jump and crash in any stadium course. Look at the stands, and sometimes the crowd will take pictures.

Hint: Train whistle:
In the gravel pit on the Golden level, go over the train towards the end at the shortcut. Do a trick while you are over the train, and you will hear its horn.

Hint: Hit the ceiling:
Go to the stunt course and get a lot of speed. Go towards the first two ramps that enter the tunnel. You should go up the sides to go straight up. If you get enough air, you will hit the ceiling. Note: Try to do a trick when you go up. It may help you get higher.

Hint: Moves:
Note: To prepare for these tricks, try pushing the Analog-stick the opposite direction, then move it in the correct way in the air. This will not work for rotating moves and some others.
