This is a little different case because the bike is normally upright at the turn-in point but, in the transition of a chicane, the bike might already be at full lean when the next turn is initiated. Granted, modern sport tires offer so much traction and chassis designs are quicker than in the past so this might not be an issue with typical situations but I'm trying to understand the dynamics involved considering that under low traction conditions or with high trail chassis designs loss of traction during the transition may come into play in unexpected ways. And I'm also trying to understand the real world trade-offs of chassis designs that vary in steering quickness.

I'm still here, my schedule just got a little chopped up and the reply program crashed an answer to the questions you guys posted and ate my 45 minutes of replies...:-(

I'll be back.

Yesterday afternoon's mailer from Mr. Code

I received my little newsletter thing from CSS yesterday, and there was a link to an article Keith wrote on crashes. I enjoyed the read, so I thought I'd share it here.

I don't understand why "hanging off" reduces the lean angle required for a turn. It does seem to work from my experience but I don't know why.
The usual explanation is because of the shift in the CG. If you could take the CG shift idea to its extreme, could you turn without leaning at all?
I would think that a motorcycle turns based on geometry, rake, trail, wheelbase and contact patch. Please explain.

Keith,

Thanks for getting this going. I've been absent as you figured out. Snowboarding actually. Heck, so bruised up and tired couldn't even get the energy to open my computer.

As you can see, you're presence here is greatly appreciated......


Folks, Keith is VERY analytical and needs "to the point" questions.

See you at Laguna in March Keith..

some questions and answers

There are several main areas of questions I see so far: Turn Entry Speed, Lines, Steering. If it is all the same to you Iíd rather stay away from the very technical physics areas of riding and chassis design and defer to guys like Tony Foale and others who are dedicated in those areas.

Let me take one of the above, LINES, and see what we can do with it.

One of the major errors when trying to correct any area of riding is to be too general about the problem. The second error is not setting any kind of goal to achieve. The third is not arriving at a simple enough, step by step way to approach and handle that area of riding.

Figuring out specifically which kinds of turns a rider had line problems would be a first step: slow turns, decreasing radius turns, big sweepers, etc., which ones are difficult.

An overall goal could be something likeóto be able to make any line work out.

One approach could be to run a wide variety of lines until you were comfortable with all of them.

Taking that idea one step at a time: decide to take a whole ride using only low, tight to the inside lines. Then later or on another ride you would run middle of the road type lines. At another time you would use the wide entry/close to the apex/ wide exit style of riding and ride every turn in that ride in that style.

Rather than the problems of each coming to you in a random pattern you would start to see what is needed to handle each of those situations, depending on what you were trying to accomplish.

In our twice a year Race And Competition Experience program what we do is set up those different turn entry positions and then we radar the exit speeds so riders can see immediately how it affects speed. In that case, speed is an indication of their confidence to use the throttle and the exercise shows them which line is best for that specific purpose.

Yes there are many technical points underlying how to gain confidence with the whole area of lines. If you had a very observant coach following you it would simplify the whole process but that isnít always practical and great coaches donít grow on trees, they are trained.

How are you doing with this type of dialog? Does it help? Itís a new way for me to do forum stuff so I want your reviews please.

Keith,

I see you are on-line. I took the 2-day course this summer at Blackhawk farms in IL from you. Just wanted to say I had a great time and learned a lot. Too bad it's hard to practice up here this time of year.

Howdy folks,

Please visit Keith's web-site and buy "Twist of the Wrist" Vol. II. It's a quick read with excellent information. Write down the questions you have. Then post...We'll get some very well thought out questions this way...

Happy Holidays!

Brian

+1 to what Brian said. Twist of the Wrist 1 & 2 is like the manual for riding better. I re-read both books every winter and refer to them when ever I feel like I am having a problem. These 2 books are the best $40 bucks that you can spend. Imho.

Keith, here's a question about braking:

How go WSB and MotoGP riders hang on when braking? For me, when I'm doing hard braking from speed I clamp my legs on the tank and get my body low, and I still feel like I'm doing a 100mph handstand. I don't mean the rear tire comes off the ground, but I end up with a lot of pressure on my arms. This makes it harder to finesse the bike, the controls, and setting up for the turn.

I see the MotoGP guys get to the end of a straight, and then they sit up, stick a knee out, and yet brake so hard they're nearly doing a stoppie. Do they simply have huge arm strength or is there a trick I'm missing?
