I'm just now getting to post on the topic of Sunday's Doc Wong riding clinic.

Anchor points are the points which you use to keep yourself in contact with the motorcycle to control the motorcycle. Suprisingly, the handlebar is not an anchor point, it is a control used for steering. In fact it is the most important control on the whole motorcycle; not even the throttle compares.
Back to the topic - Anchor points can be found by pinching the tank with your knees (expecially helpfull when going downhill), the footpegs, parts of the frame (the lower frame can be used by the inside of the lower leg) and the rise in the middle of the seat, by sliding back. In addition, the inside of the thigh can provide an even greater contact patch to the tank, sometimes sliding up to the tank to take advantage of having both thighs in contact, hugging the tank; as well as, the forearm coming into contact with the tank when hanging off. Using your chest to rest on the tank also provides an anchor point. Some taller people will use the main frame spars as anchor points with their knees.
The footpegs can be used to leverage the knees into the tank by rising up on the balls of the feet.
When going downhill the most important thing is to get your weight off the bars. Your fighting yourself trying to steer! Here is were anchor points will help you the most. By pinching the tank with your knees you have a point to leverage some support to your upper body, by flexing your back you can 'pull' the weight of your upper body off of the bars. You can turn!

You'll also be less likely to be bucked off your bike when you get into trouble and crash. Most people get bucked off because they're too tight on the handlebars. They need to relax their grip on the bars, but to do that they need another place to keep in contact with the bike, by whatever means possible; griping the tank is what most use.

Very Kewl Info. I'll have to practice that tomorow or whenever it stops raining.

Funny, I was just talking to a friend yesterday about this.  He was wondering if the bike was hard on my back, and I said that no, my thighs support my weight and I can steer with my fingers.  Good to know that for once, I was doing something right!  

Another thing to note is if you can't do the funky chicken, y'know...flap your elbows, you're too tight on the bars. Try doing that while riding, just don't let it distract you...and don't crash! I wont be responsible. It's kinda funny to see the rider in front of you doin' the funky chicken...expecially if he is on a ZRX1200, but it is good to see him practicing that. Just don't let it distract you.

Great info here. I hear people complaining all the time about their arms and hands hurting. And of course this is due to a wrong riding possition.

yup, i have to remind myself to relax my arms, and get off the bars about every 20 minutes... bad habbits die hard

Yeah right....i find that i can lean better by achoring the bike using my knees and just push the handle bar slightly to get a smooth turn.  Excelletn tip from the Doc Wong.  

good info, i was doubting the way i was riding ( locked arms. ) plus it felt like i was doing skullcrushers all day, i was so sore.
