Speed Kings

Enter ".prix3" to unlock three more mirrored modes in the Grand Prix.

Get a powerdown and boost it about 350 feet before a ramp. When you are in mid-air, hold Up or Down to perform a backflip or a frontflip. Note: You need a lot of speed and a very fast bike.

Start a new game and enter ".lapt18" as a name.

On every level, there are cameras which will photograph your speed when you pass them. Sometimes you need a certain speed to obtain "Respect". To do this easily, obtain a "Powerband". Press R2 approximately 350 feet from the camera to
Powerband past it with speeds in excess of 250 mph.

While turning, press R1. Wait until you are in front of a car and point the Left Analog-stick the opposite way that you are turning. You will keep turning, but at a slower rate. Note: Do not release R1 until you dodge the car(s).

Enter "borkbork" as a name. This code also unlocks the Secret Nevada meet, the Casino Run course, and six more
leathers, all GP modes, all bikes, all lids, and lap times.

Start a new game and enter ".meet4" as a name. You will unlock the New England, Detroit, London, and the Swiss
Alps meets; five street racer bikes; and sixteen additional single race, time attack, trick attack, and head to head
mode courses.

When you approach a ramp, get enough speed up and once you have jumped off it, hold Triangle for a Powerdow. You can actually pull it off in midair and land it by releasing Triangle before you land. You can also do this with a Surfing Powerdown, but you have to release the trick button and Triangle to land it properly, or you will crash. You can also Powerdown onto a ramp and do a rotation trick on it. Note: You do not get any extra points for doing a trick in midair, just for the jump distance.
