  1. Is he following THE DOCTOR or just someone wearing replica leathers?
  2. When the weather improves I'm going to try a new line. I think that will solve many of the problems. Shame it's only 44deg F today.
  3. I went to youtube to find a Streets of Willow video and saw this video of Peter on The Streets http://uk.youtube.com/watch?v=kU6xrs7SOCc That kid is smoking!
  4. Your reply makes sense. I took some time today to drive the course several times in my car and I learned a few things that I think will help. Thanks for the words about banking acting as a decreasing radius, makes sense.
  5. How should I gauge my desired product for this "practice area"? My corner speed has picked up 10 mph so how do I know when I'm "done"? I guess that question can be asked of any type of riding, but this in particular is non-competitive. My only judgment is the satisfaction and happiness of when I know that I got it right, which doesn't happen often. I don't understand your reference about least camber and greatest lean. A line change solves the camber problem. I also realized that I may be placing too much attention on this crack, allowing IT to dictate my line selection.
  6. You should try the lean/slide bike at the School (not sure if it is in Level 2 or 3) because it is designed for exactly that purpose; it does show you how to spin up the rear in a reasonably controlled mannor. Your question asking "how much throttle..." is difficult to answer in a vacuum. Tire pressure, tire and track temperature, tire type and amount of wear, surface conditions, lean angle, engine size and type are all factors used in answering your question ...way too many vaiables to give you a simple answer. Kevin Can you answer 2 questions: 1-Can a 600 spin the rear 2-What does it feel like In my meager experience with this sensation, I found that on successive laps I was able to get harder and harder on the gas, until I was able to roll the throttle to the stop as soon as I knew I was going to hit my apex. The tire bit instantly, bogged the engine a bit and drove forward sans drama.
  7. I've never experienced spinning the rear while vertical on my F4i and not sure if I've ever done it while leaned over either. I have however been hard enough on the gas to get to WOT (midrange rpm) prior to apex while holding it through exit and down the straight. I realized that the fear of spinning the rear and highsiding is an obstacle to standard throttle control for me and so I was hoping that someone could tell me IF and how much throttle it takes to spin the rear while leaned over on sticky tires on a 600. I was hoping to get a description of the sensation if its possible to spin it up.
  8. I have a set of turns that I use as one of my practice areas. If you're around then you may have heard or ridden "Harry S". It's the final section that in my mind, I cannot seem to find the ideal line(s). Best description I can give is that the entrance is a slight uphill, on cambered right turn that feeds into a constant radius downhill turn. The last part of the turn (tricky part) becomes (what seems) a decreasing radius with a crest on the inside at the exit. Finding a good line is further hindered by the fact that there is a crack following most of the turn. I like to be on the outside of the crack at entrance, follow the turn, and then change line to cross the crack near the end of the downhill portion just prior to the decreasing radius and aim for the inside, where I can then get over the crest and let 'er drift just a bit to the outside. I wish I had some footage to help. This stuff plays over in my mind, and I can't seem to get comfortable with the last part. I think I have a good line because I can use Throttle rule #1 on the outside of the "bowl" and allow other riders to hug the inside while I continue to motor along a few mph faster. Any advice for my favorite practice area?
  9. I bought them. One of these days I'm going to sit down and write a review.
  10. Yeah, that's true. Hence, the name: WR250. Was there something more you wished to add? Sorry, just pointing out that the R-1 is 1000cc and the WR250 is 250cc, therefore the engines have no similarity. Do you know what "1/4" means? It's called a "fraction". It can also be called a ratio or used to symbolize mathematical division. But, in this case, it means one out of four. So... "The WR250 motor is 1/4 of a YZF-R1 motor" means one cylinder out of four or "one quarter" of a YZF-R1 1000cc motor. 1/4 of 1000 = 250. Get it? I don't know if the new R1 has Titanium intake valves, and I'm guessing the cam timing is a little different, but, the measurements, the bore, the stroke, the ports, the piston, the direct ignition coil, etc etc etc are exactly the same as an R1. Hence, the WR250 motor is 1/4 of a YZF-R1 motor. The similarities are, in a word, major. r Ha ha ha ha....that was pretty clever of you. But good try though. (I got the email) Hilarious. I would call you out, but I'm going to leave it alone and just enjoy the laughter. Racer & Jaybird; What does this exchange do for the rest of us? Kevin It was all in good fun, that's all. Hope no offense to anyone else. I guess Racer and I just have "one of those" sense of humors.
  11. IIRC, John Hopkins plays Playstation to familiarize himself with tracks he's never been to before. Maybe it's the same concept, eh?
  12. I think everyone start with speed as the goal. As we mature we find that smoothness is the path to get there. Since it relates to this topic, I'd like to share this article that I read yesterday: http://www.sportrider.com/features/146_031...trol/index.html

  15. Yeah it does. A WR for the street, eh? Yamaha's answer to the KLX250SF? http://www.kawasaki.com/Products/product-s...ons.aspx?id=370 From what I've read about it, it's a detuned 1/4 YZF-R1 engine. It's a 250 dude.
  16. Chipster; Yes; like the School structure, Twist II builds upon Twist I and really has a lot of detail to help you prepare for next season. As for your 675, my bikes are just as cold now. Kevin Hi Chipster, Keith has 3 books, and they are all different. He is not one to re-hash something. Twist 1 and 2 are totally different, cover completely different material (as does Soft Sciene). Cheap way to learn stuff, the books are excellent sources. Cf ps--welcome to the forum, hadn't seen your posts before (just back from the track last night). Hi Cobie, thanks for the welcome. Also, thanks for responding to an email I sent you a good few months ago, on a Sunday no less.....now that is dedication. That combined with the way Echo has helped me in the office this last week has me loving CSS already, makes me even more eager to get to NJ in May already..... and to think my Mum told me to never wish my life away. I didn't mean to sound like I was inferring that I thought Twist 2 is a rehashed Twist 1, I just wanted to get some more info on it as Twist 2 is such a complete book and doesn't read as though it is a continuation from the prior book. I guess I'll be putting Twist 1 on my ever increasing Christmas Wish List now. Haha..How was Laguna? To bounce off Chipster's question, I have T2 and T1DVD. Should I invest in T1book or do I already have the same material on DVD?
  17. Now that makes perfect sense. So, I guess we were all right (LOL). Thanks for stepping in and clearing that up.
  18. Cards and letters can be mailed to: Andrew Trevitt Sport Rider 6420 Wilshire Blvd. Los Angeles, CA 90048
  19. Thanks for your input Kevin. The other levels are certainly not out of the question, it'd just be finances that dictate when and where. I have Twist 2 (the book) and the DVD amongst many other publications. I think I might also get the audio discs for playing in the car during my commutes (we quit riding the street as the risk wasn't worth the reward, track only now). Are there any major differences between Twist 1 and 2? Is 2 just a revised version? I am eagerly anticipating next season, my 675 isn't liking the freezing temperatures outside and wants to be set free again (already...). Where's that little button that allows me to secretly subscribe to this thread?
  20. Hello Forum This week, I hope that we can discuss quick turns. I hope that we can also get some good discussion going about it, as Keith Code says that it is 'the key to corner entry speed. Period.' I was thinking about this point as I was watching a MotoGP 125 race. They didn't seem to be turning "that" fast to me, but hey it was on TeeVee. Can someone along with the discussion of quick turn entries (quick flick) discuss their relationship to the quick 'unflick'?
  21. Very nice F4i (woop woop) Every once in awhile our club prez jumps on track with his streetbike for 2up demo rides. It's awesome (and incredibly humbling) to get passed 2-up. I found it distracting to have his tail light come on in front of me while trying to follow. (noticed your lights)
  22. Kevin, You may include me in the group that thinks daily about going track only. I am grateful EVERY TIME I return home safely with myself and my bike in 1 piece (and even the times my bike wasn't in 1 piece). But I've accepted that one day, I just MAY NOT return home. I pray that I live to be an old/grey rider, but the only part that I can control is my choices. Yes, my risk of injury is higher than driving my car with all it's stability/ traction control, ABS, airbags, crumple zones, yada yada, but this is something that I've CHOSEN. As Master Yoda said, "Do or do not" and all risk can be managed, but we have to accept that we cannot eliminate it altogether; and I think we all know that.
  23. Jay; I apprecite that you disagree with us but I missed how in your response. I can tell you from first person experience that when a car runs a stop sign through a two way (as opposed to a four way) intersection, if you were asuming that the car would respect the sign, you WILL t-bone him. I have, even with fairly quick reaction skills; fortunately for me, I was driving a car with excellent disc brakes but there simply wasn't enough road left for me to stop or to avoid him; if I was on a bike, I wouldn't be here now. You may think you can control your environment but I respectfully disagree with you on that point. Kevin I control what I can and leave everything else to HIM whom my prayers go. HE has empowered me to control much but not all. Earlier I was emphasizing the wrongful mindset of the experienced riders giving friendly advice regarding reflective clothing, loud exhaust, hi beams, etc to n00bs on how to be safe. This lulls them into a false sense of security and they get lax thinking 'I know they can see/hear me now'.
