Duel Mode tips: Take full advantage of the slipstream. Use simulation to pass through dirt quicker than usual (this is useful to keep up when the AI goes through the dirt in one of the duels).

Starting bike: I have found that the Suzuki RGV250 is the best bike to start with. Keep racing the oval track until it is fully customized.

Multiplayer bikes and tracks: To unlock more bikes and tracks for multiplayer mode you have to complete certain tasks in RS Mode.

Unlock the RC211V: Successfully complete the RS Mode and you will be awarded with the RC211V.
