Easy height in Step Up event
Contrary to what the CPU will do, you do not need to jump over the bar at all. You just need to reach its height level. To do this, rather than trying to jump over the bar and risk knocking it off, jump using the other two sides of the ramp and just air up next to it. You will know when you have reached the required height when you see your score appear at the top of the screen. All you have to do now is stick the landing.
Bail
Hold [R] + [L] + [Z] on the ground, in the air, or during a trick. Note: You can do a backflip and jump off half-way then watch it continue.

Glitch: Colorado Springs: Go through fence
Immediately after starting, take a sharp right. Turn your rider over so you are behind the Smith pads (in front of the fence). Now put in the clutch. Hold Analog-stick [Back], hit the gas, release the clutch (so you do a wheelie), and head straight into the fence. If done correctly, you should go through the fence, onto the other side. Go to your right, move around the barn, and go under the bleachers. You will see what appears to be the edge of the world to the right. If you keep going forward under the bleachers, you will get stuck and do a huge bail. Also, if you go to the left after you went through the fence and under the bleachers, you can find some huge hills. Note: This takes a lot of time and practice.
Glitch: Flat land jumping
Do not move at all. Hold the [R] + [L] + [A] and pull back as if you are going to wheelie. Once the preload is almost full, release [L] but still hold the other buttons. You should jump off the ground and be able to pull off small tricks, like Heel Clickers and No Handers.
