You can double preload to make bigger jumps; 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.
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.
Bike physics are very important in landings. Instead of leaning forward or back while in the air with the Analog-stick, press Brake to lean your rider forward, and press Accelerate 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.
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. Do a no hander and hold it. Try to land on all your tires; this will require practice.
Perform a Tsunami by pressing R1, Triangle, Up. While doing the Tsunami, do a No Hander. Your rider will do a front flip off his bike then land back on it.
Hold in Gas + Clutch. Hold Gas for about five seconds, then release. Hold Down and the front of the bike or ATV will go up.
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. Additionally, 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.
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.
When doing a hill climb, to get more traction lean back all the way up; you should fly up the hill.
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.
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.
You can get a fourwheeler to flip over backwards at the gate. A dirtike cannot flip over at the gate. After you flip over backwards at the gate, take off like usual. The game will not let you go more than five seconds forward because it will keep on restarting you repeatedly.
