  1. Congratulations! A whole new adventure...!
  2. Just a comment on this - I think the Power Ones are dual-compound tires and two things to watch for - first, the edges may wear out before the middle, the outer compound is soft and I think they do have less grip after a lot of heat cycles, so I DO think changing your tires is a good thing to try. Second, on the Power Ones I kept getting the feeling of mild front tire slips in some places, and I finally came to the conclusion that I was feeling the transition from one compound to the other as I started standing up the bike. I would turn it in, and it felt fine, then I started to roll on the gas and it was OK, but after the apex when I started standing the bike up a little I'd get this weird feeling of little slips in the front. My best guess is that when I started getting the tire on the harder compound, it was either sliding a little or just felt really different. One day at the track I changed to the Dunlop Q2s and the problem instantly disappeared.
  3. Don't have to wait for decades, the slipper clutch had already done that for bikes. Just like what DSG transmission and Nissan's SynchroRev Match did to the skill of heel & toe downshifting.... I hadn't heard of synchro-rev but I read about it and it sounds like it would be pretty fun in a car, or bike I guess! But screw the DSG, the synchro whatever, CVTs (continuously variable transmission), and the whole transmission altogether, plus clutches, torque converters, intricate valve trains, catalytic converters, and fuel injection systems... all a bunch of complicated expensive solutions to overcome the inherent flaws in combustion engines. And after all that, you still need a battery and an electric motor to bring the engine to life in the first place. People have gotten so used to these things that they take for granted how complicated it all is. And despite all the expensive and complicated emissions ######, they still end up causing smog in every city around the world. Electric engine: Attach engine to rear wheel with chain and sprockets, twist throttle to go! Max torque from zero rpms! Wheelie machine! No clutch, no shifting. Totally off-topic but just say'n, my little rant, hehe. Where is that magic battery. Getting kinda close - my daily commuter car has a CVT transmission and runs on natural gas, incredibly inexpensive to run, and ultra clean burning, so no smog and no crud in the engine, either. Oh, and I can drive it on the carpool lane. Heck of a deal and apparently a well-kept secret. (To your point, it certainly requires a lot less maintenance than those two-wheel chain-driven tire-shredding rockets in my garage. )
  4. Wow, good luck with that. I'm starting to think it takes a lot more than a year to learn suspension! It's like pulling a thread on a sweater, you just keep finding out there is more to it, and more to it, and more to it...
  5. What a fantastic post! I think I'm going to print this out and take it with me to track days. It is really, really easy to get caught up in trying to push yourself to improve entry speed and it sure can be a frustrating experience, and your post clarifies that extremely well. Recently a riding buddy of mine got really focused on entry and although he didn't realize it, he slowed WAY, WAY down. He thought he was really pushing himself, and he WAS going into the corners faster than me but suddenly I was blowing him away on laptimes, because he was losing so much on his midcorner and exit. It was a great learning experience for me to watch it happen to HIM, because when it happens to ME I am so aggravated that I can't learn a damn thing. Being able to observe it dispassionately was very enlightening!
  6. H, It isn't the full 400+ lbs of weight that one has to hold. We are talking the times a rider has saved it, when it has just gone over the edge of traction, but the tires are still in contact with the ground. How much does one have to "hold" a correctly set up bike, when it is in the turn, and the bike is moving? AND let's not forget no lean angle change (otherwise the rider would have some pressure on the bars). Any of the physics guys up here have a an idea of how to calculate this? CF I don't know how to calculate it, but couldn't you put a sensor on the slide bike, and see how much pressure is being put on the outrigger wheel when it touches down? That outrigger wheel saves slides, right? (or you could measure the amount the outrigger shock travels, and calculate it from that.) Seems like the same principle, it just adds a little upward force on the bike to stop it from leaning over any farther, and that combined with good throttle control can save the slide, right? The outrigger wheel seems a reasonable approximation to a knee slider, since knee sliders do slide easily and I'm sure that little wheel has significant drag, probably would be pretty close to the same amount of friction. Or, how about this, can you gutsy fellas experiment by pushing down a tad with your knee while dragging it and see if it changes your lean angle? It sure seems to me like it would NOT take much pressure to change the lean angle, standing the bike up a little and thereby increasing traction. I'm not reliable enough at dragging my knee to try this myself, although I think I've experienced it a few times when my knee touched down unexpectedly, and a little too hard, bouncing the bike up a little.
  7. OK, I'm curious.... how come your avatar photo is in black and white now? You are starting to look a little... out of date!
  8. Do you find it easy to look over your shoulder, when it's facing the wrong direction, i.e. into towards the bike, and away from where you're actually going. Seems pretty sub optimal to me. There are other reasons why these riders do this, but I'm not going to go into it on here. You'll find all that out if you do level 2 and get on the lean bike, and do level 3 physical drills. Bullet I'm a bit curious about the other reasons, would you mind going into that a bit more? I'm guessing that fear of leaning can make someone want to keep head or body more 'on top of' the bike, and also that hanging your butt off too far can make you get crossed up, any other reasons? I am fighting a tendency to stiffen up my left shoulder and push it forward on left hand turns, and I can't figure out what's causing it. I'm not afraid of leaning it, and I don't hang off very far - in fact I still stiffen that shoulder even when I don't hang my butt off at all. My position is OK approaching the turn, and stays OK when I get into a hang off position, but at the moment I turn the bike, I throw my shoulder forward. It's worse on downhill turns. I am right-handed, and do a lot of my steering, even on left turns, with my right hand, especially at slow speeds. When I sit on a bike on a stand, my position looks fine, and it looks OK on the lean bike too, but when a coach follows me on track they see me make a weird change in position right at the turn-in - sometimes it looks like a late look-in because my shoulder comes forward relative to my head, which sort of looks like I turned my head. Anything you can do to help would be MUCH appreciated!!
  9. I'll be there! Looking forward to it. I haven't looked at the weather yet, have you?
  10. OK, I just have to ask, did you MEAN to write "oblivious" instead of "obvious", or was that just a really, really terrific Freudian slip? It cracked me up, that's for sure!
  11. Great to meet you guys too! Will you be doing a school day? I'll be there both days at a yet to be determined corner Cool, that's my FAVORITE corner! Yes, I'll be taking Level 4 - not for the first time. No matter how many times I come to CSS, I get just as excited every single time. It's a few minutes to 4pm and I am sitting here at my desk, watching the clock, feeling like a kid waiting to be let out of school for the summer! Come say hi on Sunday - blue bike, really fast-looking.
  12. Mine showed up at my house this weekend! It's fantastic, way beyond my expectations. I 've read and read the books and been to lots of schools but still got plenty of new information from the DVD. And it's entertaining enough that it's easy to watch straight through... which I did... but now I want to go back and watch it again because I know there is more to pick up from it. The animations are incredible, gives you a perspective you could never get from a book or from watching someone ride. After seeing the DVD I am astounded by the scope of the project, what an impressive undertaking, and what a spectacular result!
  13. Yes, it was great to meet you and if you're working this weekend you will indeed seem me soon! I'll be there Sunday, and my husband will be there both days. Wheeee, I can hardly wait to get out there!
  14. If we can't use Flash for Cobie (although Flash Jr. is pretty funny) maybe it should be Streak. I hear he has earned that one.
  15. Hey there, I'm not sure if this is the right place to post this, but there are FIVE short video interviews with Keith Code that have been recently added to the www.twistofthewristDVD.com website. The interviews are terrific, they have a lot of information about the making of the DVD (including clips from the movie and photos of the sets and locations), and some history about Keith and the school, and discussions of Keith's coaching techniques, etc. They are really interesting! They are on: www.twistofthewristDVD.com One is on the Home page, two are on the "Making of" page, and two are on the "About the DVD" page. They all say "On the Throttle" so you can probably find them on the On the Throttle site too. Be warned - I was just going to watch a little bit of one, but I got hooked and watched all five in a row!
  16. I'm eyeing that Nov 21-22 Vegas date myself. I like Vegas, very flat but I like the series of left-right-left-right turns, each getting faster than the last... wheeee!
  17. Oh boy! The asking questions routine again! I've read the section in TOTW II, where it talks about pushing on the pegs and other parts of the bike to get leverage on the handlebars. Obviously you can't push on the bars unless you are bracing yourself against some other part of the bike. Where I find it most difficult to implement is the full transitions from one side to the other, where ya gotta make the hang off position change nearly simultaneously with the push on the bars, hard to be locked onto the bike in that scenario. I've messed with the goemetry/suspension a little here and there. So far I've never found it to make that much difference in steering feel. For the moment I'm convinced its overrated, but I've never had the help of an experienced suspension tuner. In the end it's always a compromise between one advantage and another, and no matter how light you get the steering, you'll always want to push as hard as possible to go as fast as possible in chicanes, and that will take as much physical effort as you can put into it. In other words, if your goal is to go as fast as possible, a quicker steering bike would allow you to go faster, not push less. If it were a magical setting that allows you to turn with so little effort, why are the pros tired after a race? Are they doing it wrong? Have the wrong settings? No, they're just going as fast as they can! Bike settings might make it easier at any given speed, but that then just allows you to push it to the next level, either way you've got to expend the effort. All I'm say'n is, while we can make some improvements in technique and suspension settings, in the end it will take some serious physical effort to go fast. Maybe I have a basic misunderstanding on this, but is seems to me that you want to push FASTER, not harder. And intuitively, it seems like the more effort is required, the SLOWER you'd be ABLE to make the motion. Imagine trying to quickly push open a really heavy door versus a super-light one. So I think finding ways to reduce the amount of effort required would help you quicken your steering. So I think there is value in either making the bike easier to steer OR finding a way to change your body position or steering motion to require less muscle! Regarding fatigue, when I am riding as fast as I can go, I get tired from holding onto the bike during braking, and from the cornering forces, but not from the steering. I don't think I've ever worn out my arms from steering, even in endurance races. I certainly do not have exceptional arm strength! I found that steering got a LOT easier for me when my coach at a school worked with me on quick turns, and I learned to steer with a fast and very focused, deliberate movement, with a STOP point. One quick motion, then relax. Before that, I would push the bar and then remain very tense, stopping my arm motion by unconsciously resisting with my other arm or my shoulders, and wasting effort throughout a lot of the turn. Now, it is a much smaller movement, it has a MUCH more dramatic steering effect, and it's not tiring. For sure as the entry speed comes up in a given turn, it takes more effort to turn the bike, but for me this is still a relatively minor effort compared to holding on during really hard braking, or hanging off in general!
  18. Just to add another angle on this, have you taken a look at your bike setup? I've got my bike set up a bit lower in the front and higher in the back than stock, and it is VERY easy to turn. By comparison, my husband's Ducati takes a lot more effort - but it's also more stable through the turns. I think his bike is hard to ride, he thinks mine is scary as hell. Even set up this way, a suspension guy watched me going through a chicane, told me the bike was wallowing in the middle of the transition, made a change to keep the front more stable through the chicane, and WOW did my transition speed improve. The first time I tried it, it flicked over so much easier I nearly ate the inside curb. So if you are finding it takes a lot of effort to turn or you aren't getting through transitions quick, you might try steepening your steering angle or adjusting suspension settings.
  19. I vote "Flash" for Cobie, partly because he's fast, but mainly because of his tendency to change clothes in full view of classrooms full of students. Oh wait, is that one already taken by a UK coach? Darn...
  20. Like lwarner said, Level 2 sorted me out on this, too. I'm curious, what particular sights or situations seem to make you target fix? Someone about to turn left in front of you, or change lanes into you? Holes in the pavement, or slick spots, or curbs? Or does it happen when you are trying to go fast? Do you notice it happens more when you are tired? A little more detail on when it occurs might help us give you more input on this. The best way I know of to manage this is to make sure you are not tired, and not riding over your head. Target fixing is the FIRST thing that happens to me when I am tired, overheated or dehydrated, and often happens when I am 'trying too hard' to go fast, or ride a certain way. As far as exercises... if there are particular things that make you worried, like pavement snakes or the edge of the road, it might help you to intentionally (and slowly and safely) ride over or close to them to take the mystery and fear out of them. Acknowledge that it's there, you know what it is and how it would affect the bike. Then the worry about what "could happen" usually goes away. Same goes for hard braking; try it, safely, a few times and then when you really need it you won't have to stare at the pavement in front of you, as we all tend to want to do. The Twist of the Wrist II DVD might help with this, too, lots of info on survival reactions. Of course it's all in the book, too, but it becomes really, REALLY clear when you see it on film, especially with the on-board camera view.
  21. Go for it on the nickname thread, that might actually get Pete up on the forum (I work him too hard to get up here . Here are some of the names: James Toohey: Hammer Lonnie Etter: Dawg Kristi M.: Hot Laps Pete: Wipes I don't know that all of these will stick, we are trying them on, but another thread, get your "suggestions" sound good to me! CF OK, where's the nickname thread? I'm suggesting "Shades" for Dylan, cuz he always seems to have to funky sunglasses.
  22. Hi Dave, Welcome to the forum, glad to see you found it, I'm sure you'll have a great time cruising through all the great info on here! Did you order a Twist of the Wrist II DVD, too? I ordered mine a few days ago, I'm pretty excited to see it released. It was nice to meet you and Sof, and it's a lot of fun to exchange ideas with other CSS students - talking with you reminded me to use my two-step better, and after I followed your line once through Turn 7, I happily adopted it for the remainder of my day. So, glad I helped you out, and you helped me too. Hope to see both you and Sof again soon, I'll be at CodeRace in a few weeks if yer up for a challenge!! Hotfoot
  23. I would think that if you are way leaned over and had a bump, dip or change in camber in the turn you could have ground clearance issues, like unexpectedly scraping a peg, that might not have happened at your previously lower speed. Is there something specific (other than running wide) you are concerned about happening, if you go in faster?
  24. If you ride track days there is often a photographer tehre, so you can see how mmuch you are leaned. I was looking at my photos and saw some bike parts pretty darn close to the pavement, decided I better work on body position and quick turn a little more!
  25. Conversation overheard between my 3 year old son and his babysitter: Babysitter: "What's THIS in the picture?" My son: "It's a Duc!" Babysitter: "Nooooo, honey, it's a MO-TOR-CYCLE." Sigh. Some people just don't get it. My son likes tractors, too, so I anticipate some confusion when he identifies a Caterpillar, or a Deere.
