  1. General question to the CSS team: I attended the 2 day class. There was no fitting done with regard to sag settings for the riders. Isn't that important? There was quite a range of rider size and weight, but I don't recall anybody setting up suspension for riders. What are the thoughts on this?
  2. Yesterday I was riding a loop of country roads around my home. I know the area well enough to know where I am, but not well enough that I remember every curve and corner yet. I was exulting a little too much in the glory of a sunny day and dry roads, and i ended a straight section with too much speed to make the corner without drastic and dramatic actions. This could have been very bad. Fortunately, I didn't react...I acted. Kept balance, didn't hit the binders, kept my head and body into the necessary line, and rode the tightest corner at speed I have every made in my adult life, without a slip, slap, or shimmy. Came out the other side centered up and in control, and promising myself I would never ever ever do that again (a favorite lie I tell myself). I count this as the first notch for CSS. Specific training at CSS made this possible, whereas prior to taking the course I would at least have been doing some weeding, and at worst been having a yard sale out there in East Snohomish County. Considering taking the 2 day class? Consider what may happen if you choose not to.
  3. Just for the record, this is the best discussion ever. I have learned a TON here. Thanks to all!
  4. Ah yes, cornering master. That is my pathology. I'm working on it, but it's not going well....
  5. I thought this post was heading toward a question I have been working on. If you are in a turn, and following rule #1, are you not heading for a low-side if you over cook it? Specifically, the idea of 'rolling it on smoothly, evenly, and constantly'. With a high end machine, this can very easily move from 'just enough' to just too much. Please help me out here. This is a daily question on the road, and I am just very unsure if I should be getting all my speed in the short straights, and railing the corner, or if I should be intentionally entering corners with less speed to allow for more to develop during the corner through this steady increase. The 60/40 rule seems right, but technique seems to be everything. An important note for my area: It's western Washington, and damp roads are expected 75% of the year, so the line between grip and slip is a little narrower.
  6. I think back to the nearly unrideable bikes of my youth. The Kawasaki H2 750 leaps to mind. The bike was designed with the track in mind, and top riders at that. Then it was sold to the masses for use on the street. The power band was narrow, and when you hit it it hit very damn hard. 'learning' to ride it was just learning how to not die. The S1000RR on the track was my only experience with a sport bike, and for a machine with such big numbers in power and torque, it seemed like a cinch to ride. I have to assume it's not my native talent, so that would be software correcting for my attempts to push outside the design parameters due to ignorance, supporting what CoffeeFirst posted above. My new ride has ride modes, 4 from the factory and one you can edit at your peril. These are now a necessary part of the modern sport bike, precisely because they are for sale to people like myself that are enthusiasts that are STILL LEARNING. Meaning, of course, that we make a lot of errors. So, to Jaybird180 I would say that the ultimate goal of a rider may well be to learn to ride the bike to the edge of computer intervention. To actually know by experience and feel where the edges are before the nanny functions step in.
  7. This is an expression meaning to let the suspension return to a neutral position with no influence by power or braking inputs. Think ‘glide’.
  8. Do you sit on the seat and pilot your bike around the track, or do you crouch with your weight on the pegs at all times? Keith makes reference to weighting the outside peg in TOTW II. This is what you do? For the advanced racers: Do you have a home position on your bike that you always return to, or are you constantly moving your body, or at least your weight distribution, while you ride?
  9. Two simple questions came up in class at CSS, and as you might suspect, the answers are not so simple. First: What did the engineers build your motorcycle to do? Second: What are you doing with your motorcycle? (or, What did that poor bike ever do to deserve that treatment?) These two questions have stayed with me every day since class. Here is a good example of why that is: Riding a long twisting downhill country road, but with traffic. Usually this is a favorite section, but at 45mph it's very boring. There is no place to pass, so you just have to ride it out. The easiest thing to do for me is to leave the bike in a mid-gear, 3rd or 4th, and let the massive engine braking of the boxer twin maintain the slow speed down the hill. Is this what the bike is designed to do? Absolutely not. Everything is wrong with this. All the drive gear is now loaded on the wrong side of the gear teeth, the rear tire is braking, but the suspension is loaded wrong because the braking force is not loading the brake calipers and effecting the swing arm member correctly. Add the fact that you are strangling the motor to produce drag. Then, you get to the bottom of the hill, and roll it on, shifting all the weight back to the rear wheel, unloading and the loading all the running gear on the opposite gear faces, and of course causing your engine to hiccup while fuel and air mix are adjusted to 'drive normal'. This transition is both sloppy and very uncomfortable. CSS informs me that the right move is to either ride the brakes down the hill consistent with design intent, or at a minimum clutch it before you hit the bottom of the hill to let the suspension heal, and then roll it on smooth to property load the bike. Long explanation, but you get the idea. Consciously trying to ride the bike the way it was designed to operate is actually much harder on the street than it is on the track, but there some rewards to be had in terms of machine wear and tear, and rider comfort. Plus, little things like suspension actually work if you consider what you are doing and why.
  10. At the two day class at the Ridge in Shelton, WA CSS provided the gear. The gloves were Alpinestars, as were the boots. Day one was rain. Fortunately, it was a nice warm Washington rain...so not too bad. We all got wet, and spent the day in soggy leathers, but strangely, my feet stayed dry. The gloves got wet, but not too wet to take on and off. I was impressed enough that I went shopping for Alpinestar gear when I got home, but the same gear is either not made anymore, or it's only sold on 'black sites' known only to the inner circle of CSS. Does anyone know anything about this? The only track gear that seems to be coming from Alpinestar today is all vented desert style race gear. Up here in Washington we tend more toward Gortex then perforated leathers. Any input would be welcome.
  11. Your idea is exactly right for me too. I have to create a new routine to try to be aware of and solve my bad habits. It's not easy. I was/am a rookie at this, so my experience is 100% learning new things, but I am not new to racing, or pushing the limits of powered vehicles. Two things of significance come to mind: The act of cornering causes tires to 'crab'. for the length of the contact patch, the lateral forces are bending the tire away from 'straight ahead neutral'. The more the force, the more the bend, until you lose grip and the tire slides. With carts and cars you can feel where this happens and with judicious use of throttle and steering you can use this to your advantage to really increase corner speeds. I have to assume that for the talented riders this is true on motorcycles, but because steering is caused by counter-steer which increases the crabbing effect, that adding lean acts as a multiplier, not an additive forces, and as Hotfoot said, you pass the point of slipping too fast to manage the recovery. It must be a fine line. Also, as I understand it you only change the shape of the contact patch by adding lean. To change the size of the patch you need to change the weight...which takes me back to Hotfoot reminding me that throttle is a suspension input. It has a directed and immediate effect on weight distribution. In off-road racing sliding both tires is what you do all day long, but you are also tossing the center of gravity around with body english, something that seems much more tricky (to me) on pavement.
  12. Fresh out of CSS it is only reasonable that I was working on riding skills while commuting to work on my bike. Visual skills in particular, with emphasis in picking turn in points, pre-apex, end points. Thinking 'big picture' and then picking points on the road surface. Great idea, but this was not a track, it was a road. When I was a kid we were taught defensive driving. My instructor would do stuff like slap the rear view mirror out of alignment and then ask you how many cars were behind you, what color? Gaining or falling back? The same questions about who was ahead. Watching for brake lights five cars up. Is the road wet or dry? Are there leaves down? What was last night's weather like? My favorite was being asked to imagine you are a bird 200' above the car. Can you hold a mental image of where you are and what is around you, and who is on the road with you? In the military they train Situational Awareness, or SA. It's similar, but basically requires you to learn to assess and consider what and who is around you at all times. It's not easy to do, but it's surprisingly informative if you work at it. So, there I was on my commute, carving corners and focused on the road surface, and I passed a deer on the shoulder doing around 70. Me, not the deer. And I had to shock myself back to reality. Yes, big picture on turns and lines is important, but out on a domestic roadway, the even bigger picture focus on your local environment is much more likely to keep you upright and healthy. This was, I think, an untended consequence of the CSS experience, and I only post it here for your consideration as a reminder to stay in the 'here and now' of your daily riding. Rob-
  13. The cost of the 2 day class is pretty close to the cost of new Ohlins for my RnineT. I actually had to make that choice, and since I come from the old school 'ya run what ya brung' way of thinking, I figured that knowledge beats out hardware most days. Boy was I right. What was really marginal, harsh, and unresponsive suspension is now completely smooth, responsive, and supple suspension. As it turns out, putting yourself in the right place AT ALL TIMES and having your awareness focused on what is happening in the relationship between your yourself, your motorcycle, and the road surface....well, that changes everything. Of course, a new set of Q3+ doesn't hurt either. I can't count the number of off-road events I participated in where the cool guys with the best gear got their asses handed to them by some fat kid on a clapped out 20 year old dirt bike. Riding skill is riding skill, and they don't sell it on Revzilla. They do actually sell it at CSS however, and besides being fun as hell, it is hands down the best suspension improvement I have ever made. This is not exactly news to anyone on this forum, but I just had to crow a little. Rob-
