  1. MOTORRAD explained why a bike will try to go straight when the brakes are applied midcorner like this:

     

    "Uprighting momentum" comes from the contact patch moving sideways from the tyre's centre line, creating a lever effect. Together with the brake force, this lever will twist the wheel inwards, a phenomenom we tyipcally refer to as counter steering. The result is a bike righting itself unless the rider counters with an equal amount of force. Generally speaking, the wider the tyre, the bigger the righting force. With the brakes on, the testers measured up to 250Nm twisting force at 12 degrees lean.

     

     

    Interesting that it was measured, cool.

  2. Regarding the sign ups, what we have found is they can change so fast in the office (with people signing up on the phone), we thought it was better to handle it internally, rather than show it on the site. Another reason for that is if a person cancels, and a spot opens up but the website doesn't show it yet, someone might not sign up that could.

     

    Besides, we don't mind talking to people, weird huh?

  3. This was posted on Triumph675.net and has been making its rounds around the Internet.

    The photographer did an excellent job of capturing this crash in motion.

     

    The reason I'm posting it here is because I noticed something interesting when someone made this animated GIF of it...it wasn't as easy to see in the stills, but when the shots are lined up, it becomes obvious.

    The bike begins to pitch in earnest in frame 5 of the animation. Can you spot the "survival reaction" in frame 4? :o

     

    Rider was OK, by the way. :)

     

    Squirrels, good observation on the SR, yeah, it's clear!

  4. Nice plug Cobie. You just reminded me that I need to buy the DVD.

     

    I'm pretty shameless about plugging that stuff, aren't I?

     

    It's been around, looks a little older, but it's not like the information isn't still applicable. I even worked in that video too--I remember diong one scene where I was supposed to miss a car on a curvy road. I was crowding the yellow line a little bit, and the car (driven by the director), was supposed to be a little over the yellow. Well, he was WAY over the yellow, and I really did darn near hit him! Not much acting needed in that scene :)

  5. What are the component pieces that make a good coach, in this sport, or really any other for that matter?

     

    Here is one piece that has to be there, and pretty darn fundamental: observing. And you might think to yourself, "Cobie, that's pretty obvious dude." Maybe it is, maybe it isn't. But that ability to simply observe what is happening in front of you, this is not a skill of minor importance.

     

    What do you guys see as another skill in a good coach? (or comments on the above).

  6. The wide view, as I tried to explain in my own way earlier, makes things slow down dramatically more often than not. You will run a smaller risk of getting surprised by other traffic, obstacles, change of road direction etc. However, as I also mentioned, relying solely on the wide view on public roads is - IMO - a bad idea because it will obscure things like small patches of sand, oil, bumps and dips etc since the peripheral vision isn't sharp enough to notice them, nor are they always visibile from a distance. Hence road riding demands - IMO - a constant alternation between the wide view and glances on the road quite close to the bike. Eyes must move constantly. On a track, with a known surface, scanning the road is of less importance and keeping things "slow" is of greater importance.

     

    At least that's my take on it :)

     

    There is a bit more information on the VW as it is covered in the classrooms currently. Not trying to be secretive, but I can't put it down in a few works all the pieces that Keith (or Dylan/Stuman) go over in the briefings.

     

    I'll say one thing: if one could keep enough space out in front, and still keep track of tihngs that happen closer in, would that be an ideal situation?

  7. Once your bike is leaned over, I believe Keith stated that you can take your hands off the handle bars (assuming throttle control), your bike will continue leaned and on its line.

     

    I just read an explanation on this. Before this can take place, you will have to have reached a "balanced" state where the centrifugal forces are equal to the forces trying to pull you towards the ground, usually when leaned over about 50 degrees (due to the width of the tyres). When the bike is leaned over less, let's say 20 degrees, you cannot expect to maintain your line if you let go of the handlebars.

     

    There is an interesting shot in the Twist 1 (yes 1) video/DVD, that shows Keith on a CBR 1000 I think on a skidpad and leaned over, holding the throttle with 2 fingers, thumb and forefinger I think--has anyone see this shot recently? Don't think he has much pressure on the bars at that point.

  8. Hi Andrew,

     

    That is like what we often hear at the school. You can read it, but then getting someone to watch you doing it, how well (or poorly) can really be a help.

     

    One thing that came up recently with a student was really making it clear to him that a key part of the curriculum is making sure the students know what they are doing correctly, like really sure. We often get asked, "Hey, tell me what I'm doing wrong" and that does get covered, but the other side is just (maybe more) important.

  9. Sean,

     

    I'd agree with Rainman: the visual skills will be the key to this, but what is done at level 3 will also make them appear a bit differently (many riders get more comfortable getting lower on the bike and that does have an effect on the visual skills).

     

    I'd also agree that if you do level 3, we won't ignore what is happening with your visuals, and that gets you 1 step closer to level 4, where we can do an individualized program.

     

    I'd suggest moving on to level 3, we'll sort out the visuals as needed. One point that you might consdier is have you ever had the idea of using a end of braking marker, or speed set point (as opposed to just a beginning braking marker?)

  10. April 5, back in the office.

     

    Just finished 6 days at the Streets, a little cold the first day, the rest all good. It's official, the bikes are pretty darn cool, and our crash numbers are very, very low.

     

    So much for fast bikes==more crashing.

     

    CODERACE was very entertaining, Peter Lenz started from the back and still won. Lex Hartly has a 250 racetbike, but had mechanical issues on it, so had to resort to his 150 four stroke, no real match for the 125.

     

    We have now got 3 different classes so riders will race with others of similar experience. Except Thomas Patch. Thomas came out, did well, runs '38's, did all 6 days in a row with us--and he is 68 years old.

     

    All you guys (hereafter referred to as "whiners) that think you are too old, better re-think that one!

     

    OK, that's as close as I can get to blog/facebook/tweeting/myspacing. :) Maybe this thread is too old and I should nuke it anyway.

  11. lol....long story short is. i told jason i dont use RP's i just go with the flow of the track and my bike!

     

    right now arizona has only CCS to offer, my dream is AMA. Bigger yet, wsbk!

     

    i am as of now watching the twist of the wrist II

     

    thanks for the warm welcomes!

     

     

    Welcome Matt,

     

    There is more on reference points in Twist 1, but let us know what you think of Twist 2?

  12. Hi, this is GeorgeR from Greece. It's a pleasure to be a member of this forum. I consider myself as an open minded student that wants to improve his skills every single day! Lots of respect to the administration team, tutors and all of you guys! My current bike is a Kawasaki Versys. ;)

     

    Welcome George!

     

    Out of curiosity, have you been to our school in Greece?

     

    Don't know if we have had any one review it yet, you could be the first.

  13. Hello,

    I just bought a set of pegs for my 749s, and I am not sure on how much up-down and front-rear should I position them.

    Basically the reason I bought aftermarket pegs, is that the OEM Ducatis were slippery, making my foot slip off the peg during turns.

    According my CSS instructor, that happens cause I am to close to the back of the tank, making my outside foot twist to the outside and then slip off the peg. Of course he is right, but I am very short

    and it is difficult for me to hang off the bike keeping one fist distance between the back of the tank and my .... and at the same time having my arms relaxed on the clip ons.

    As for the up-down positioning, I found out by trying to see which position helps me hang off the bike better (lock my outside leg better on the tank and put weight on the outside peg effortlessly).

    So I've positioned them at the higher/front slot and it seems to me better.

    Does that mean that my knee will start dragging on a deeper lean angle than before?

    Another question is, what difference does front-rear position is making in riding?

    Here is a photo of me making that mistakeIMG_small.jpg

     

    I'd go for what will get you able to lock on to the bike the best. I have short legs, and last time I used rearsets I was ecstatic, really made it easier to get locked on. Another thing that you can try is either Tech Spec, or Stomp Grip tank pads. They can help quite a bit.

     

    Front to rear position on the bike I don't t hink that critical, much more imptant will be you being able to lock on, and then get loose with the upper body. If a fist's distance is too much, try a little closer, OK to experiment and get a good position. The Duc tanks I've riden on have been very square, and I couldn't hang of them much at all.

  14. Ok, I agree with you (& Lyle) that it is still a weakness. It is fear based. I'll work on that. Thanks for the encouragement...I felt like I really progressed...too bad i got tired at the end. Hey, I am really excited because i hooked up with a group here and went for a short ride with someone who says he knows you, Tom Roach. He is part of the Palm Desert Area Desmo Owners Club :ph34r: . Based on the few guys i rode with they are very good riders and safe. do you know these guys? Are they legit?

     

    Tom Roach--haven't heard from him in a while--they used to come and do our Harley only schools we did way back when, mid 90's.

     

    As I recall riding was pretty decent.

  15. Andrew,

     

    Stuman already answered, and Oz chimed in, but those 2 together is the source of more crashes than we can count. I had 2 guys at a previous school, worked with them all day long to NOT do this, and they both crashed later in the day, reverting to old habits. They were so happy, had made huge changes, but they still slid back into that old mode of doing the 2 together!! Neither was hurt, minor bike damage (both in the same slow turn, but I was unhappy--they were my guys!
