Seat Bouncing

Now that Anaheim III is just a memory, the Supercross show heads to the East Coast(ish).  Hopefully, after bills and food, my next paycheck will be enough to cover a ticket for Daytona.  Regardless, the man made tracks of Supercross and more natural National tracks are obviously very different.  The bike set up, riding style and way of training are 2 different animals.  However, there is one particular thing that can be used in both; that happens to be seat bouncing.  Although seat bouncing isn’t used that often in National style tracks, having it in your bag of tricks can make things a lot easier on your body and lap times.

As with most jumping techniques, seat bouncing is not for beginners.  However, if you are comfortable with getting some air time, then start small when learning this.

Okay, now that the disclaimer is out of the way, let’s get to this.  One of the most important parts of this is to find a balance between speed and seat position.  If you are coming out of a tight, inside corner, you can sit farther back on the seat.  However, if you are sitting in the same spot, but going twice as fast, things aren’t going to end up well.  Your shock is speed and weight sensitive.  If you are traveling at a high rate of speed and sit on the back of your seat, the shock is going to have a big load on it.  When you hit a jump, all of the speed and weight are going to compress the shock further down than if you were sitting on the gas cap.  When it rebounds, the bigger load will send more momentum forward…possibly enough to send you over the bars.

Enough physics.  You have found your ratio between speed and seat position, now what?  Well, as with any jump, you want to approach it straight and steady throttle.  Blipping the throttle while trying to seat bounce is bad…believe me.  As you get to the face, you want to be in your seat, positioned properly and maintaining a smooth and linear throttle.  The farther up the face you go, slowly apply more gas.  This keeps the power to the ground and the rear wheel spinning, which helps the front end stay up.  As the front wheel leaves the lip, you want to pull the bars and lean back.  Each jump is different, so finding a balance between leaning, pulling and applying throttle will take some time to get used to.  All of these combined put extra load on the shock and enable you to jump higher than normal.

For some people, standing up as soon as they are air born is right.  For others, they wait until they are at the peak of their height to stand.  You will know when you have to stand up and get ready for the landing.  Again, don’t try this on a huge double if this is your first time seat bouncing.  Start small on a table top and work your way up.  The more you do this, the better is feels.  Take it slow and you’ll get it sooner than you think.
