When delivering a bike and Cass and his gang appear, they will try knocking you off your bike by swerving in front of you. This will make you wipe out, losing 200 style points and a good amount of your bike's health. To avoid losing style points, wiping out, and damaging your chopper, press FRONT BRAKE. Cass or one of his friends will hit you, but they will fall off their bike and you will receive 150 style points.
