  You must position your body slightly forward as you leave the face of the jump. As you come off the lip, "bounce" off the bike, by pushing off of your footpegs using your leg muscles. Aim your knees to an imaginary point about 4 inches above the cross bar. Bring the front of your ankles up to the handlebars (on the inside of your hands, but on the outside of the forks) and "hook them" to the bars. As you do this,increase the tension in your arms (pull on the bars a little) -- this will help bring your knees over the bars as well as line up your legs with your body. Once your feet are secure on the handlebars apply more tension on your arms. This combined with the extending motion of your legs and arching of your back will "pull" your whole body over the bars.As you arch your back, you may want to throw your head back. This looks very good and will also help you extend your body. Some riders choose to close your eyes, however, I opt to leave them open. The reason for this is because some riders may become disoriented as they view the terrain or sky behind them.

Note: When you are working up to this trick, an important step is getting your knees over the bars. That is the single most important move. How far you bend your torso is completely dependent on your skill level and airtime. Its important that you have good judgement in the air so that you know when to bring your torso and legs back to the bike.  A natural feel for the bike  and the jump is necessary for doing these tricks because you can't see the landing as you are approaching it. Don't ever go to far. Work up to a full-out cordova in small increments because landing in the cordova position would be a disaster (duh).
