                Best MX Bike
                The best mx bikes are the 500cc and they land a lot easier on the
ground so you wont fall off as much.
             
                        
                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.
             
                        
                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.
             
                        
                Easy tricks at Boston
                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.

                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.

                Stuck at Gate
                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.
