  1. After watching this video, I have greatly improved my lock on the tank, my body position, my endurance, and have also finally been able to unweigh my bars under braking. Before I tried being further back in the seat and grabbing the tank with my knees. All that did was make me exhausted. https://www.youtube.com/watch?v=HeMSfgb5tks
  2. Curious of your thoughts of my buddy in this picture. I do not know if I have ever seen such an aggressive body position before. Has he crossed the fine line of being fast vs being a monkey?
  3. I did a track day yesterday at Arizona Motorsports Park, and as I scrolled through the event pics, I noticed that there were two good shots of my friend and I where I could overlay them. So I did. What I find is interesting. Though we both have nearly identical lean angles and are fairly square to the bike, my friend (GSXR 600) is in a much more aggressive position. My question would be is one more right than the other? We both talked about it, but neither is quite sure. Will he have more ultimate traction on exit due to lower CG, or do I have more control and save energy by not getting too low? Interestingly, we also run nearly identical lap times. I corner faster and get on the gas sooner on exit, so he never gets a good run on me on my SV650.
  4. Wanted to update this thread with another piece of information which may have lead to the incident. Several months ago when I was riding on the street, I decided to stand up on my pegs and lean over forward to look at the front wheels at speed. It didn't look smooth. Almost as if I was absorbing a lot of tiny bumps. Once I got home, I put the bike on the front stand and spun my wheel to check the run-out. To my surprise there was a significant dent in the wheel causing the tire to shift as much as an inch in the area where the wheel damage was. I have never seen this damage before and believe it's probably been like this since I have bought the bike. I'm hypothesizing this may have ended up the biggest contributing factor to my front giving out in the corner since a quick loading and unloading on the contact patch would wreak havoc on the front's gripping ability.
  5. Reduced engine braking with a slipper clutch? Count me out! I find it interesting in the moto world that having some driver aids is acceptable by enthusiasts and then in the auto world they're all looked down upon (power steering I guess has fairly accepted). I come from a big auto background, so my first instinct is to think that all the slipper clutch guys are just being a bunch of nannies. I remember I was having trouble with downshifts when I first started riding, but after several weeks of riding I swapped to "GP shifting" and suddenly I was a pro (maybe the wrist and ankle rotating in the same direction helped my timing?). But now when I ride other bikes with normal shifting, I have no issue; probably because moto controls are no longer foreign to me. You surely can practice downshifting under braking on the street. You can do it under low braking conditions. Just like learning heel-toe in a car on the street, it may be a pain in the ass at first, but you'll eventually get it, and even if not completely, you'll most likely have no trouble at racing speeds as less finesse is required. Don't give up! You want to be able to ride any bike on the track. How unfortunate would it be to be given a chance to ride some sweet bike on the track and then be disappointed that you can barely get around the track because you just don't know how to deal with a normal clutch? Just my opinion
  6. Learned something fun the other day which may have contributed to my low side. I found the build thread to my bike made by the original owner on the SV forums (http://www.svrider.com/forum/showthread.php?t=121455)%C2'> have learned that my tires are 6 years old from time of manufacture (checked the tire side wall) and 4.5 years old from time of purchase and have roughly 10k miles on them which includes at least 6 track days. :eek::shifty::confused2: I never suspected old or bad tires due to how much tread they seem to have left.
  7. Not the cones fault I for some reason second guessed myself on that corner that lap and fixated on where I didn't want to go. Plus, I was on the front brake when I hit the dirt
  8. In that video, from the camera's POV, I would have went down at 1:16, but taking a wider line. For a better perspective, check out my video from my first track event where I took a similar line. At 00:52 is where I went down. Thanks BENHAMF15, that helps a lot.
  9. Have read "A Twist of the Wrist 2"? No, just seen the movie. Which tire gave way... front or rear? I am not 100% sure, but I would say it was the rear since the rear end of my bike spun out away from me in the slide. As you were adding your lean angle, were you rolling on the throttle at the same time or did you stop rolling on before you steered the bike into a steeper lean? What specifically were you doing with the throttle relative to your steering inputs in the corner? I am fairly certain I was rolling on. On what lap did it occur? It was mid session, so I was probably already at least 7 laps in. Were you using tire warmers? No, just using street tires, so why would I have any? Was the lean angle you were at when you crashed significantly more than it had been in the previous lap or two (i.e. a sudden leap in speed in that corner)? I wouldn't call it a sudden leap in speed and angle. I doubt I added more than a couple degrees. Have you had your suspension set up for your weight (i.e. set the sag)? Somewhat. The bike is stiffly sprung. Even with the forks at full soft I cannot reach a "proper" sag. I matched the rear sag relative to the front, so to keep a balance, but that would mean that overall the bike is stiff. I will add one more thing. My friend that was with me that day said that in the same corner, he noticed a significant crack that ran concentric with turn and that when he went over it he felt his rear end slide out a bit but was able to ride through it without issue (as far as riding he s more experienced and had significantly better rubber as well). So this could have also been a contributor, as I also widened up my line to set up for a later apex. This could have put me in a bad position in relation to that crack in the road where it would not have been a problem before.
  10. Today was my third ever track day and things were finally coming together for me in terms of being more comfortable with my body positioning and the lean angle of the bike. I ride a SV650 for reference. During my third session, I was increasing my lean angle still further and therefore was able to increase my overall speed, so I was feeling pretty good. Then it appears as though I took it too far. I was already in a corner and wanted to tighten up the turn with a bit more speed, so I increased my lean a touch further and the bike just fell from under me. I am somewhat perplexed about the situation, though. Considering my bike is mostly stock with stock rear sets (just has GSXR 1000 front end and zx10 shock) I thought for sure that even if I didn't drag knee, I would at least drag hard parts before I would hit the limit of the tires. The tires are Road Attacks, which I hear is not that great of a tire, but I figured you should be able land a knee with most tires as long you aren't pushing the traction limits with excessive throttle input in a corner. I thought about blaming a dusty track due to my slide being almost completely on my ass and my pants still look brand new (thought the leather would be torn up at least a little), but I am not sure. I'm still a motorcycling noob and I don't know how to perceive what the lean limit is. I feel as though I had to low side to be able to say "there's the limit, now I know", but that does not seem intuitive to me. There should be other signs to help you, right? My background is in racing cars and karts so this two-wheel thing is still somewhat of a mystery to me
  11. Cool, I understand now, but I guess I will always be one of those guys who says to learn how to drive/ride the "hard way" before leaning on technology (use a slow car/bike, no ABS, no TC, heel-toe [is there a moto term for this, like finger-wrist? lol] ). I still think blipping should be learned at least so that just in case get you to ride your friend's Ducati with a dry clutch, or if your clutch ever fails to disengage, you can still downshift effectively. I can downshift 100% smoothly with no clutch at all while just engine braking.
  12. Not to be critical or naive (I only started riding 3 months ago and only have 2 moto track days under my belt), but why are you dragging the clutch on downshifts? I see you downshifting under braking and your right hand is doing nothing with the throttle. I know that every once in a while I will under-blip the throttle and get a rear tire hop or slide, but I wouldn't think that I'd trade throttle blipping for dragging my clutch up. I understand most of our clutch's are wet, but is that enough for them not to glaze? BTW, great thread! I am exactly in the same boat with cornering and my track pics look similar to the first ones you posted. Hopefully I improve as quickly as you did
