again, thats the right thing to do, especially at the track where hanging off is appropriate. get your body over and also weight the inside peg. the weight transfer of your body position lets the bike turn with less lean, and having your weight on the inside peg helps the tire edge grip, not the opposite (which would be conventional wisdom). when you're ready to straighten the bike up exiting the turn, switch and weight the outside peg which will help straighten the bike.

this shot shows what I am talking about:
body off to the inside, my weight is supported by the inside peg and my outside knee on the tank. I am consciously weighting my inside peg. I can actually lift my outside foot off the peg without effect. bike has significant lean angle too.

 :laugh: to me it looks like your weight is being held up with your knee that is draging  :dunno_white: but what do I know, I have I would say around 2" chicken strips on my rear tire...no rush to really take a turn that fast and lean that far over  : :laugh:

hahaha, knee is barely skimming the ground. This was taken a year and a half ago so now I touch even less-Once I touch to know where I am I pull it up a bit...

yea .. your just letting your knee do all the work  :cookoo:   :icon_lol: .
as far as the  dirt in the corner thing .. i try my best as i am coming to the corner to try and make a fast scan of it and look for any dirt or gravel ect.  that might be there .. this help when me ,css,stray  all went to big bend last year .. i came in a few corners a little hot tell i seen the gravel/dirt and let up and set it up a little so i was not so far leaned over that way if i did slide a little i could maybe keep the tire sides up :) .. stray on the other hand was not that lucky :( .. but he got it fixed and was ready to go later that day ! theres on intersection here on my way to work that i really get a good lean in to just cuz i can :) .. but i noticed some red broken brake light covers laying in that intersection so i backed off before it was to late :) you would think it would mess up your cornering (the look threw the corner bla bla bla ) but it dont

Pablo, we must be saying the same thing, but in different ways.  It's confusing to talk about weight, because with all the forces going in, it really only makes sense to talk about pressure.  But thinking about it in terms of "weight" makes it easier to think about.

Your weight is inside, of course, just by virtue of where your body is with respect to the contact patch.  The question is how much foot peg pressure you're using with each foot.  I've tried it both ways, and putting pressure on the outside peg gets me around the turn faster with less lean angle.  If you press the inside peg, you carry too much lean for the turn, which looks great in photos, but doesn't get the job done as well.

I went around this one turn two dozen times gouging up the pavement with my inside peg until I realized what the instructors were waving at me about.  By shifting foot peg pressure to the outside (still leaning inside for damn sure) I could breeze through it and started wishing the other bikes would get out of my damn way.  (There was a no-passing rule in effect for that corner.)

I'm not making this up.  That's from TOTW2, and what they taught me at the track.  It works.  Some of these links talk about cornering in bad traction situations, which actually brings us back on topic, but all of them regard highly "weighting" the outside peg:

Sometimes when the roads are bad (ice, dirt, gravel, water, salt, sand, etc) I think it would be nice to have training wheels. Yes, I know that sounds weird.  :cookoo: I'm not sure if they could be bought as I've never searched for them (might be surprised). It could be a beefy but small wheel with a strong hinge attached at the wheel hub where a shock would run from hub to the wheel at the end of the hinge. The hinge and shock would allow the bike to sway either way but at a certain point, keep the bike from hitting the ground. I would have liked something of this nature when I first learned how to ride. I remember I got on my GS for the first time, not realizing the touchy throttle, hit the gas, did a little wheelie, and fell over five feet away. And for some reason, the three times I've laid it down it has only been on the one side.  :cookoo:

Thanks.  :)

California Superbike school use a bike they call the slide bike or something, to simulate power sliding during turns on the race tracks - you have probably seen Hayden and Rossi doing it a fair bit. But anyway the bike has training wheels at the end of an arm on each side of the bike and basically you try to make the bike slide and it falls over onto the training wheels - at the sort of angle you would be cornering at, so you could get your knee down. This allows you to practice sliding without falling off.

are you not talking about the difference between low speed and high speed turns, i.e. in the low speed turns you keep your body upright and lean the bike over, and in higher speed turns you lean into the turn?

And as for the white truck, what an @$$hole.  if I crashed here I would be surprised if no one stopped to help. Hopefully thats an aberration and not the normal state of affairs there... are ppl hard in your town?  :icon_razz:

My first day I dropped it in the pouring rain trying to u-turn to park to get to an audition... car behind me startled me. Some guy helped me pick it up and was very consoling.  :cry: The lady behind me let me wave her off. Then I came back and dropped it again when I got on it (parked on the inclined side of the street). I crashed into a jeep that had lost total control on the freeway. 4 ppl stopped. It got backed over by a waitress (she left a note... but then again it was in front of her own workplace). Some asshat parking garage pressure washer knocked it over breaking his own leg (I hunted him down and extorted minimal repair cost from company). And the wind or some idiot knocked it over this week. But somebody picked it up. So its a crazy dangerous world out there but ppl can be helpful and kind too.  :dunno_white:

oh and previous owner was on a base in CO where the wind blew it over coupla times. But it's still like 95% good as new.  :cheers:

Jeeze your unlucky Indy.

When i came off a month or so ago it was about 10.30 at night so it was dark, the bike was on its side and i couldn't pick it up due to broken collarbone and slipped disc in my back. I had rung the parents and they were coming down to help but this car driver coming past slowed right down and rolled down his window and said i would help but i just don't know this car its a rental car, then drove off. I was like WTF you can't help me because YOUR driving a rental car your not familiar with. You obviously know how to stop the damn thing. At this point i knew my parents were only 5 mins away so i wasn't really angry just more shocked and amused by how crazy that guy was.

am I unlucky? I hope I am and that this isn't the normal rate of damages to a motorcycle. I was wondering recently how ppl keep their bikes so nice... and how they can afford to spend like 8-10k on a new bike when it's just going to get knocked over anyway.  :icon_mrgreen: Maybe its just luck, or my living in an urban area with a bunch of rain-addled doofuses. But is it bad? If I do get a "total loss" payment with no liability on my end for the last accident then I have made back approximately double what I paid for it. (from doing my own labor, hunting down the guilty criminal scumbags who did these things to my bike, and letting some things slide). its been a Buddha Loves You of a lot of work, time, and heartache, and it's got a couple flaws now, but still in pretty damn good shape. Most of all, thank modern society for the wonderful thing known as insurance, and liability.  ;)

Hijacked... lol

Good info on turns for the track tho.

Superbike school has some awesome equipment, awesome procedures, awesome ideas.  That would be one of my dream vacations.  With so much mythology involved in riding, they seem to try to figure out why things work and go at it in a very systematic and learned way.  Very cool in my book.

Hey Chuck,
There are lots of theories to going fast on a track and TOTW2 is one of my reference books on the subject. What works for one person may not work for another. Thats one thing I love about having all these references such as Code, Iensatch, Pridmore, etc.
I understand what you (and Keith Code) are saying, and I've put that to good use as well. I used that idea of strength from outside foot to inside hand to great effect, but more often I need more weight on the inside, particularly on turn-in, holding until I'm about to get on the gas on exit, then I weight the outside. Regardless what Code says, this does help me get the bike straightened. For me, at my pace, I find using the inside peg to "pivot steer", in addition to my outside knee pressure on tank and outside forearm on tank work much better. But others may have different results.

Its like what a racer I met once told me: There is no right line through a turn. Its whatever gets you through fastest, given whats going on around you. So sometimes you need a different line to get past someone, or to protect your inside line, etc...no one method of anything is perfect all the time.

I still dont think your weighting the inside peg is what caused you to crash. Like you said, you used to drag all sorts of things before trying the outside peg method. Tells me that even if you were putting pressure on the inside peg, even if you were dragging hard parts, the bike could be leaned over more, since you had previously cornered while dragging parts successfully. Make sense? I would examine other aspects of your crash to see what else could have caused you to crash. I dunno-I'm just rambling at this point...

That's ok, it's a good discussion, still only half-off-topic.  :laugh:  What I was doing at the time was accelerating hard around a corner that I was getting better at over the course of the day.  I found I could get around it faster each time by putting more of my weight on the outside peg, but when I went down I was thinking about another bike near me and whatever I was doing, I wasn't thinking about how to behave with my body.  I could feel how much pressure I had on the inside peg, but I wasn't thinking enough to lighten up.  Since my body weight was on the peg, which was on the ground, it wasn't on my tires, which took away some valuable traction that I needed while I was accelerating pretty hard (yes, even in the GS).

I'm sure there were a dozen factors involved, including too much power, too much lean, less-than-optimal tires, weak suspension (still using the GS shock at the time), and so on...  any one of those taken away would have been fine, but what I really "blame" is what I was trying to control at the time and failed, which was my balance of foot peg pressure.  So no, all other things being equal, simple foot peg pressure wouldn't take me or anyone else down, but as part of a symphony of factors, it can be the final straw.  (Holy mixed metaphor!)
