Body position on a bike is definitely a personnel feeling. If you are not dragging hard parts then don't worry too much about your body position. Yeah, you may not look as cool as Ben Spies, but it really doesn't matter until you run out of ground clearance, Just stay relaxed and comfortable.
Now with that said, I used to hang way off the bike and twist around the tank. The CSS coaches fixed my body position so that I could be more relaxed and in control of the bike. Here are a few things to keep in mind.
- Outside knee and thigh should be pressed into the outside of the tank.
- Lock the outside knee into the tank by pushing against the outside peg.
- Do not twist around the tank.
- Try to rotate the inside knee out as far as you comfortably can.
- Your upper body should follow your inside knee so that you are leaning low and to the inside.
- Rest a portion of your torso on the tank and rest your outside arm on the tank.
- Use the balls of your feet on the pegs.
Everybody is slightly different and doesn't do this exactly the same, so just work on it and see how it goes. The object is to get the weight low and to the inside.
Good luck,
Shane
