  1. Aircrftr, my uncle is a pilot so I've been fortunate enough to have gotten some air time in and what you said is true of an airplane. Also, thank you for the information. I was actually just going to see if I could come up with some way to test this for myself. And I have to give you credit for your idea. That was actually pretty cool . Thank you much for the information.
  2. I'm sure that most of us here are aware of countersteering and that it's the only reliable and controlled way to turn a motorcycle at speed. What I am personally not sure of is what the front wheel of a motorcycle [at speed] is doing after countersteering and the bike is in a lean. We all know the concept. Push right, go right. Push left, go left. But does the wheel eventually turn back into the direction of the turn? In other words, pushing right will --obviously-- cause the wheel to turn left. Once into the turn, however, does the wheel turn back to the right? At slower speeds while weaving in and out of cones, I know for certain that if I push right, the wheel will eventually turn right once the bike has started to lean (don't believe me, take a cruiser through some cones at slower speeds). What I am not certain of is what is happening at higher speeds. Is my observation simply based on the fact that while weaving through the cones, I'm not going fast enough for countersteering to be necessary? Thank you in advance...
  3. Funny that you say that because somebody just mentioned how Collin Edwards likes to get his head way down, which is causing his front tire to wear more than his teammate, Rossi. From what I understand, it was suggested that he try to get a little more use out of the rear tire. But you're right, Mladin does seem to stay way down. It's working for him, but then again, he's not in MotoGP, either .
  4. I'm just curious, what are the professionals doing? Watching Rossi, I believe I see him blipping the throttle, but it happens so fast that it's hard to tell.
  5. This is what I was afraid of. Under heavy braking, the rear wheel is limited by traction enough as it is. If I were to come in hot and brake heavy while down-shifting a gear or two (with or without the clutch, mind you), I could easily fathom an instance where there isn't enough back-torque available to induce a slip of the clutch, which could inevitably result in an unexpected slide of the rear wheel.
  6. I just read an older article by Keith about proper down-shifting technique while entering a corner. Personally, I learned this technique on my own and have used it with great success since I was a young kid riding dirt bikes in the field. There weren't, however, slipper clutches back then (that I know of) to help with correcting miss-shifts. To this day, I continue to blip the throttle while braking to match engine RPM with the speed of the rear wheel (even on a bike with a slipper clutch). My friends and I were recently having a discussion regarding our technique for entering a corner and any of the newer guys that have never learned proper down-shifting techniques, refuse to blip the throttle while entering a corner. They believe it to be a waste of time (which I totally cannot understand) and simply kick it down sometimes two-three gears at a time without ever blipping the throttle or letting out the clutch until after their last shift. My question is, on a bike equipped with a slipper clutch, what is the proper technique for down-shifting? Do the same rules still apply? Aside from the obvious fact that it's more strain on your tranny and clutch to NOT blip the throttle, I believe it's a disaster waiting to happen when an improperly configured slipper clutch suddenly grabs and locks up the rear wheel without any time for the rider to react. This is why I look at a slipper-clutch as a tool to hopefully correct a miss-shift, if it were to happen. What do you guys think? Thank you in advance...
  7. I'll definitely call and check. Thanks for the reply.
  8. I'm very interested in attending a class at VIR this spring but I will be a little short on cash until around the middle - end of January. Will I still have time to sign up? I'm sure you will only be guessing on your part but can you please give me your best guess using previous years as an example? Thanks... P.S. I still haven't decided on 1 or 2 day but it will definitely be for level 1.
  9. I'm not sure if this is related but I've had a problem making right hand turns (usually when making a somwhat slow and tight 90 degree turn onto another street) where the front end feels like it just wants to dive or like I just grabbed a hand-full of front brake in the middle of my corner. I'm actually on the gas as it happens so I can't imagine that I'm overloading the front end in any way. I also weigh about 135 lbs and the front end is definitely stiffer than I think it should be. In addition to this, I've definitely noticed that my bike tries to force me to go wide when making slow right-hand turns like was mentioned by Blue636.
