SX Superstar Cheats

To get turbo speed you have to do a lot of tricks in uk stunt arena
after you have done a few tricks look at the bottom right hand corner
and there will be pink stuff when u have enough press the Z button and
you will use turbo but when the pink stuff runs out it runs out (oh ya u
have to land the tricks and get the points).

Since the back flip trick goes very fast and looks unrealistic, there is another and much better looking way to do one. Use the "Bigger air" trick. After you launch off the ramp, hold Back and you will do a better looking and more realistic back flip. You can also do a front flip like this, but it requires some skill, and big air.

On the bike selection screen high light a bike and press Z,r,r,r,r,r,r,z,a
You will unlock a new level where the bike rides the person

To get bigger air, hold L as you go up the ramp. Release L (ideally when the gauge is full) at the lip of the ramp.
