If you have ATV Off Road Fury, put it in and save the game. Then you put part 2 in and create a new profile, Save it on the same memory card! After it gets done it will say G-Ride stuff has been unlocked. You get Boots, Gloves, a Helmet, Clothing, and a pimped out ATV!
To start the cheat off you have to enter FLYPAPER in the cheats menu. Play Freestyle, Pick a half decent jump to catch some air, then Pull all the way back and do a trick while in the air. Note: Make sure that you hold the trick buttons when you land)
Then land on your back with the wheels leveled to the sky. This will allow you to do as many trick combos as you like!
This cheat is cool. you first have to get or have played atv 1 and saved it then if you have it go to it and save atv 1 and then go to atv 2 and it will say congrats you have unlocked the G-RIDE.
