  1. Lots of good data from some of you and especially Hotfoot’s info. Here’s just a bit more on the subject of Pivot Steering. May be repetitive of some data already written but look it over an do the experiment at the end for fun. My statement in Twist II about getting your weight closer to the center of mass or center of gravity by weighting the pegs rather than the seat and any implication that it alters the center of mass (COM) or center of gravity (COG) was, or helps in any way is, for lack of a better words, junk, incorrect, wrong. Weight in the seat or on the pegs does not change

  2. This thread started me thinking. Dangerous, I know. Some riders, very good ones, claim they just know where the tires are and can hit a tight apex. I can't but I'm happy for them. Knee to curb is workable, or, more descriptively, Knee Over Curb. 9 out of 10 students reap substantial improvements with that drill. AS Hofoot said, she can't see the tank on her small bike and if body position is good, with head low and turned in to the corner, it may be similar on a big bike. The more "GP" the body position the less tank you'll see. One other thing just struck me as a possible

  3. Great to see the responses on this. Some years ago a coach missed T-boning a car at an intersection. This boulevard had a median, and tall curbing on the street-side edges. The car pulled across the median and then stopped in his lane. He steered quickly right, but had to also steer it back left (or hit that tall curbing). Both the visual skill (of not target fixing) and able to turn it quickly, are practiced skills, saved his bacon that day. It's a recommendation for simply getting onto a track now and again. Practicing riding technique in a controlled environment is ben

  4. This is a very broad question. The answer will depend on a variety of factors about the corner: radius (and whether it is increasing, decreasing, or staying the same), camber, surface (grip, bumps, etc.) so I am not sure what sort of answer you are hoping we can provide. If the radius of the corner is increasing, and the camber is either unchanging or getting more favorable, you should be able to accelerate through the corner, however if the radius is decreasing and/or the surface is going off-camber, you may have to be slower later in the corner instead of faster. A corner with a crest i

  5. Whew, this thread has gone all over creation and back since the original posted question, and the OP seems to have checked out. So, I'm going to jump in here. I am a CSS coach. First let me note that Yakaru is a very competent rider, fast, has come to many schools, and is very knowledgeable on the material. Now, on to some of the info that is in question. 1) When a rider is in a corner, if the throttle is APRUPTLY shut off, the bike will INITIALLY stand up a bit and run wide. Sudden loading of the front tire creates drag on the inside of the contact patch which tries to turn the

  6. One drill we commonly use in Level 4 is "knee over curb". The idea is to find a point of reference other than your head/eyes to use, to judge distance to the inside edge of the corner. If you approach the corner with the idea that you are going to try to put your knee over the curb instead of positioning your head over it, you can see (looking at your photo) that your tires would be at least a foot closer to the inside, probably more. Another advantage of using your knee as your reference is that most riders can SEE their knee in their peripheral vision, which helps to judge position over the

  7. Hanging off moves the combined center of gravity of bike and rider more to the inside which allows the bike itself to be leaned over less. With the bike more upright, the suspension works much more efficiently which improves traction by keeping more of the tire in contact with the road.

  8. Your collection of data and research shows you are barking up the right trees. Here's some more data regarding tires: Per the Dunlop engineers tires grip in 4 ways: 1) Adhesion--the temporary chemical bond between the tire and surface. 2) Keying--the tire deforming and filling in all the nooks and crannies of the asphalt or squishing into the depressions. 3) Abrasion--the tire tearing from itself or wearing away. 4) Hysteresis--the energy storage and return by the rubber and partial conversion to heat. The first two can be looked at as static properties and the la

  10. I liked the sound of this too so thought I would try it out before writing. I like the idea of using the outside peg to 'triangulate' a point of the tyres' contact patches to the peg, to create a better idea of where the bike is placed, pretty much as El Colibri found. Also, that our awareness of using that outside peg should already be 'switched on' if we are pivot steering (which I assume we are). As it's new to me, I did find my attention was then slightly focussed at the rear of the bike, which then felt like it was playing catchup as the bike moves forward - perhaps this is just ho

  12. The best pressure setting can vary by bike/rider weight, by track, and by temperature and is not always the easiest thing to figure out. Best thing to do (assuming you are talking about track riding) is to ask the Pirelli race tire distributor, and be specific about what bike you have, what pace you ride (A, B or C group at local trackdays, for example, or tell them your typical laptimes), and whether it is expected to be cold or hot out. The Pirelli range given above is a good starting point; if you see any abnormal tire wear (tearing, or uneven wear) occurring, you can ask a tire provi

  13. They have full gear, so the same undersuit suggestion applies to women as men. as for school vs camp: I get a lot more from the camps, personally, and favor them for the increased time per day on the track to refine things. But it’s something I can see others wanting more “processing time” for the lessons or not physically prepared for two full days of riding having the opposite opinion. In the end though I’d say it’s probably not a drastic difference either way — both will be effective so pick the one that you think sounds more appealing or fits your schedule better.

  15. Faffi adds an excellent point; a little stiffness in the arms (a common in-too-fast survival reaction) will restrict bar movement, add load to the front, and potentially add some countersteering input that leans the bike over farther which can VERY easily overload a front tire that is already near the traction limit. Some braking references in Twist II that might help you (the OP) on info about leaned-over braking: Ch 24 Braking sections "Efficient Braking", "In-turn Brakes", "Crash Statistics", and "Brave or Smart". Also the chapters in Section II on "Rider Input" and Section III on

  17. Yes, riding the NO B/S Bike with Josh Galster behind me...outright terrifying. Let's the stage: Josh was a pretty solid AMA Pro, racing 600 Supersport at the time, good rider. We were on the NO B/S Bike, and came pretty close to the camera car (seemed way closer on the bike than it does in the video). At what seemed like the last possible moment Josh would reach down with his thumb and steer the bike away from the car. What you might not be able to see is how hard I was pressing on the NO B/S bars--surprised they didn't bend. Veins popping out of my neck, trying to steer the bike (w

  18. That movie changed my life. I had been riding (commuting) about 5 or 6 months when I figured I was ready to ride some twisty roads. So I went out and scared myself pretty bad. The bike wouldn't turn, I was crossing the yellow repeatedly, my wrists hurt from my death grip on the bars, etc. Every corner was terrifying; a "mild panic" as they say in the movie. It was a bad day. Then I found TOTW2 and I felt like Keith had just watched me ride and was going over my mistakes, one by one. The entire movie was a series of "ah-ha!" moments. Everything was explained so well. Now I've done a bunch of sc

  20. A lot of this has to do with the specifics of the corner but for the general approach: - You usually want to shift the weight balance forward to change direction. Depending on the bike and corner this can vary from a pause in the roll on, a partial roll off, a complete roll off (preferably with intent, not just chopping the throttle), or application of the brakes. - Once on line you roll back on, moving the weight back, stabilizing the bike. Again depending on the corner and bike the nature of this can vary. There's a corner at one of my local tracks which, on a 250cc bike, I do

  21. Sorry to hear about the down. I think Apollo has the core of it, and if your lecturer didn't say to obviously use the brakes if you needed then that does seem to be an oversight. I'll put a clip in at the end from the Superbike UK's level 1 presentation -- should jump to 18:16 -- which is the clearest explanation of 'how' and 'why' to do the drill (including using the brakes if you must). In my experience, the no-brake drill is best approached in a stepwise manner and helps tune entry speed and understanding of slowing from things other than the brakes (tire drag, lean angle, engine

  23. Being a mediocre rider with a history of more brawn than brains, I have had to stand the bike up to slow down before continuing at a reduced pace countless times. Sometimes from running out of cornering clearance, sometimes just running out of courage. I have never planned for it or practiced it, it's just a result of my SR.

From participating in some other forums I DO understand the questions/concerns that arise when you don't know the sources of the information you get. This particular thread covered a whole lot of ground in a short amount of time, and got confusing, but from what I saw most of what was said was correct in one way or another, just incomplete or stated in a way that was not absolutely clear. Perfect example is the question of what happens when you roll off the throttle in a turn - one person said the bike stands

  25. I think we need to clarify whether we are talking about "weighting" the outside peg or talking about PRESSING on the peg. Pressing down on the peg with your muscles to force you knee up into/against the tank can improve your lock on and that is a nice benefit. Using the outside lower leg as a strength base for pivot steering is not weighting the peg, it is using the peg as the most stable pivot point. (Just standing on the peg doesn't work for pivot steering because that is not the same as locking your lower leg to the bike.) If a rider senses an improvement in the bike's handli

  26. Personally, I prefer a softer carcass and a more rounded profile for the tire. That's partly because I am a smaller rider and most bike's suspensions are too stiff for me anyway so the softer tire helps absorb some of that, but it is also because I like to feel the tire react - I like to feel the tire "set" in the corner, and feel it compress under acceleration. I do not like to feel rigidity or vibrations, or feel like the tire isn't reacting or won't compress, that sort of feedback tends to make me feel like the tire is cold or has too much air pressure and won't have adequate grip, so I am

  29. I'm a big fan of small, lightweight bikes. To me it seems pretty hard to explore many of the capabilities of a 1000cc (or even a 600cc) sport bike on public roads. You can barely get to third gear. I picked up a Kawasaki Z125 recently and I am having a blast with it. Street legal, but in ten minutes I can have the headlight, taillight and blinkers off it and it's ready for the go-kart track. Is the handling amazing? No, but it isn't bad and it IS fun to ride. It is NOT a highway bike and has a low top speed but if you ride it at 30-40 mph you feel like you are really riding, on the S1000r

  30. It definitely can be done (sliding an S1000rr in a controlled fashion) and you can watch high level racing and see it happen. The school also has an off-track tool called the Slide Bike that can be used by more advanced riders to find our what it feels like to slide the rear tire. (And, for that matter, there is the Brake Bike that can be used to find out how it feels to slide and recover the front, in a straight line on the brakes.) One thing to consider is that the tires are ALWAYS sliding, to some degree, it is a built in part of how they work. In any corner the tires are always scrubb

  31. The brain is not typically wired to be bothered with words like "don't" and for most will only react to "fixate". If your kid has ice cream running down the chin and you tell the kid "do not look down", the child will definitely look down. If you instead say "look up", you can wipe the chin before the kid ruin the shirt.

I love it when topics get resurrected, and especially when I have just discovered the technique, literally yesterday...it forces me to relate my newfound exuberance not only to the "what" but also the "why." I am not a proud author and I am seriously interested in all responders. Why? Because if what I know to be true as outlined below proves false - I need to know ASAP. First, kudos to the CSS Coaches who asked the poignant question and provided the illustrative example: i.e. Cobie's 'stirring the pot' getting the topic back on track, "Does it matter which peg is weighted?" and then Ho

  33. I have been told that weighting, or rather pressing down on the outside peg allows you to corner faster and safer, as it encourages you to put your head and shoulder weight, and not your butt, inside the turn (aka: kissing the mirrors), which requires less lean angle in a given turn/curve. (Your upper body weight leaning into the turn replaces some of the bikes weight it would use in the lean, requiring less lean angle on the bike) Ive taken turns where it seems the bike stays almost upright, and I'm able to hug the inside line nicely in the apex of long curves. It helps as well as it puts an

  34. The answer to the question is: from turn-in, off throttle, not trailing the brakes, the bike will slow at the rate of between 3mph to 8mph/sec. Lots of variables of course but that's the quick answer.

  38. Hi guys, I hope you're all doing good. My name is Olivier, and I'm a riding instructor in France. I never took a CSS class, as we don't have a French CSS. But I read the books, watched the videos and been lurking on the forum. This one is the best I've ever seen on motorcycle riding. I trully believe that the techniques described by Keith can be used on the road. I had a flash yesterday. Correct me if I'm wrong, but PS is not rotating around your knee: it's all about pushing your body forward, isn't it? Thanks and have a good day.

  45. Hi CoffeeFirst. I have two street bikes. A 2014 RnineT, and the 2020 SR/F. The SR/F is the heavier of the two machines, and it feels significantly lighter. The center of gravity is very low and centered, and first thing to contact the ground on either side would be the rider, so no clearance concerns. The 'problem' I have been harping about is that Force=Mass X Velocity. Without the auditory or physical reminders of your speed, and the linear nature of the torque curve it has happened many times that I become aware of the mass of the machine only as I realize I am running out of

  46. This is difficult as to a point these skills will play off each other. So, my opinion (based on street riding, not track though they are likely the same): #1 - Visual skill, lack of target fixation. You have to see the situation or threat before anything else can happen. #2 - Quick reflexes. Once you see the threat/issue you need to make the right reaction. #3 - Ability to steer quickly. If you need to change direction, this is important. #4 - Physical Condition. Its important so you can enjoy your ride and not be fatigued (and sloppy) #5 - A lowly last is Brave.

  47. Great article. I have met people from all six of the categories you show above! I was in the #4 group for a while. Then I took Level 1 at CSS and it made a HUGE difference in my riding... but I thought all schools would be that good and went to some other schools and got a lot of general riding advice and was kind of in category #5 for a while. Then I came back to CSS and did Levels 2 and 3 and made massive improvements again - and right after that I was bumped up at my local track days from the "slow" group to the "intermediate" group and then right into the "fast" group. What a difference!

  48. A couple of things strike me: - you had the presence to think under such stress and use a brake you rarely use - you didn't get full effect from the brake since you skidded - and you still made the corner! In other words, you now know that you can brake MUCH deeper than you do and carry mucho more cornering speed. This is a particularly good thing
