Reading the posts it seemed like they just weren’t sure of the maximum traction available from the rear tyre when you’re exiting turns… That’s something I’m working on as well. Back when I had a GSX-R600 I remember that I could just open the throttle to the stop once the bike had come back up to a certain lean angle and it would feel like I was riding a sling-shot out of the turn (maybe it was only in a couple of turns where I was exiting a gear higher to allow opening the throttle, but it still felt like I was coming out fast and there was a really noticeable ‘sling-shot’ type feeling!). But now on a 1000 I’m still trying to get that feeling again (if it is even possible on a 1000cc bike? Maybe not, since they sure have alot more power than a 600!) 

But one thing that has helped me to find the limits of traction is to keep pushing slowly, opening the throttle a bit sooner, then a bit harder, all the while looking for a ‘sign’ from the tyres that they’re nearing maximum traction. There’s no rhyme or reason in adding more throttle if you don’t know the end result you’re looking for. And no, the result we’re looking for isn’t just to ‘go faster’, but to use maximum available traction. If you’re taking it easy and making small steps in adding throttle then the tyres and bike will tell you when you’re nearing max traction - you may get a little spin/slip/slide from the tyres or the bike might buck & weave a little. Even if you do slide a little, it still may not be the case that you’ve achieved maximum traction since it usually isn’t that sudden (especially if you’re making gradual, controlled throttle inputs). Remember that there is a gradual transition from static friction to sliding friction, if you have a bit of a slide it’s probably not accurate to think “oh no, I nearly crashed!”. If you have a little slide, you’re really just starting to enter that sliding friction zone. So thinking about finding that limit - if the tyre isn’t sliding, then you can add more throttle. Simple! 

I know it seems kinda simplistic and obvious to say that if the tire isn’t sliding then you can add more throttle. Well, duh!!  :P  But the thing is -  there is no real ‘answer’ to the question of how much throttle you can use, there are a million factors that influence available traction. But if you are able to find that place between the transition from static to sliding then you’ll be able to answer the question for yourself on any turn, any bike, and using any type of tyres.

One final thing - I found it helpful to prepare myself mentally before trying to find that limit. Now every session I go out on track I fully expect to slide (even if it’s just a little), and I keep drilling into my head not to chop the throttle, which of course is a very important point if you’re sliding.* If you are expecting to slide, you’ll be able to be much better prepared to handle it. It’s not likely that something can frighten you or catch you off guard if you’re expecting it. ;)

* A kinda funny side story: I had just starting to ride my mountain bike more, and was riding along the street and crossed a driveway to get onto the footpath. The front wheel had gone over a little bump and left the ground for a second or so, problem was that I was in a slight turn at the time. Funny thing is that I reverted straight back to old motorcycling habits, and since it felt just like a little front end slide I actually thought to myself “no problem, it’ll grip up again soon.” Which would have been true on a motorcycle. So I just stayed completely relaxed and didn’t make a move at all. Of course I went down - and I was initially surprised that the front hadn’t hooked up, then I remembered that the MTB doesn’t work quite the same - and I remembered the right thing to do would have been to put my foot down and ride out of it.  :P  It’s funny how the mind works when you’ve worked so hard to drill in a certain behaviour. On the plus side I was barely grazed thanks to being so relaxed when I fell, I was expecting a good rashing from that one. 

Anyway, that’s my thoughts on the topic. What do you think - is this kind of thing interesting, or should I stick to posting photos?
