Want a really cool cheat? Of course you do! Okay, if you're in career mode, and you're on the very first track, than wait till you get to the first turn (if it's not the first turn then it's the 2nd one), now turn around it as usual. You should see a line of trees. right after you go around the corner, use the clutch and go as fast as you can. Now, back to the line of trees. let your left handle bar barely hit the tree, as soon as this happens you should fly so far into the sky, that you will go off the screen and all around you will be white. Eventually you'll come and fall back down... cool...
