Gary says there are six motocross jumping techniques. He points out two of them in this short video riding tip. These two are the most common. One is "launching" to get more height and distance, the other is "absorbing" to stay low. These are just two of the "55 Absolute Techniques of Motocross" which are all listed, explained and shown with illustrating pictures in Gary's popular "Motocross Practice Manual."
