and no handed
To land no handed on an ATV or a moto bike, do not get too much air. Only do this at the Super Cross or Nationals as you cross the finish line or something. Do a no hander and hold it. Try to land on all your tires. This will require practice.
Bigger jumps
To make bigger jumps you can double preload. Double preloading is when you preload on the bottom of a face and at the top. Just preload as usual, only preload at the very bottom of a jump. Then on that same jump, preload again at the top. This will make you go a lot farther.
Boston: Easy tricks
When doing freestyle mode with an ATV or dirtbike, there is a building where you can go up the ramps to get reach. When you get to the top, there is a location where you can fall off. When you get to the top quickly accelerate. When you fall you get a lot of air for tricks.
Easy store points
The easiest way to build store points quickly is to go to the high point challenge in freestyle mode. Once you are driving, try to pull of as many backflip combos as you can on every jump. Once finished with the round, you will receive half the stunt score in store points, sometimes even getting 100,000 store points in only a one minute run. The dirtbikes are slightly easier to accomplish this with.
To get fast and easy store points, go to single player mode. Do freestyle mode for about ten minutes and you should have about 1 million store points.
Golf Cart
To unlock the Golf Cart, you need 80 race points.
Hill climb
When doing a hill climb, to get more traction lean back all the way up . You should blast up the hill.
Landings
When riding an ATV, try landing more on the front of the vehicle. When riding a bike, land more on the rear. Doing so prevents that particular vehicle from crashing as easily. This is especially useful in freestyle modes.

MX landings
Bike physics are extremely important, when you are in the air. Press brake to lean your rider forward somewhat, and press gas to lean him back. If you are going 50 mph or more in the air and are going to land on a flat surface, do not release the gas. Doing so when landing will prevent your rider from flying off as easily. It has to do a lot with the rider's and the bike's momentum. If you are trying to land on a hill, which can be difficult, you must adapt to what part of the hill you are landing on. If you are going to land on the face, you must either hit it at the same angle, or lean back more. If you are going to hit the top, lean back so your back tire hits first.
Plane vs. helicopter
Have a friend in a plane chase you in a helicopter. Go to the corner of the map. Just before you get blown away, have your friend come after you. If he misses you, he will get blown away. Dive down for a better chance for him to miss.
Point gaps
There are hidden tricks within the Nationals tracks that can be found in free ride mode. One is in Goblin Gulch. In order to do this gap you must be in free ride mode. On one of the big berms on the track is a stone tower. At the bottom of it is a picnic table area. Go to the picnic area from the berm. Jump it and you will get a picnic gap worth 9,000 points.

Uphill challenges
When driving a golf cart on the uphill challenges, the easiest ways to make it is as follows. When the green light flashes, quickly accelerate. Run into the other golf carts to knock them off the mountain or hill.
Wheelie
Hold in gas and clutch. Hold gas for about five seconds, then release. Hold down and the front of the bike or ATV will go up.
