I think the disconnect is in the wording...
    10° lean + 40 MPH
    vs
    10° lean + 70 MPH
The 70 MPH circle will be wider...

    10° lean + 40 MPH
    vs
    30° lean + 70 MPH
(I'm just guessing on numbers) will be about the same...
Right, this is all good.  But Jake's original post still doesn't make much sense, at least as far as turn radius go.

I wasn't trying to add lean angle into the equation.  As you enter a corner, the lean angle increases.  As you exit, it decreases.  As you exit, speed increases as lean angle decreases (with proper throttle application).  As speed increases the radius of the turn you just made (not the road) will increase, taking you to the outside of the turn until evetually, you're not turning at all but rather going straight.  But having said that, even with a constant lean angle, as you pointed out, an increase in speed will increase the radius of your turn.  So you did help.  Thanks.

Here is what you may not be understanding: with a constant lean angle, an increse in speed will increase the radius of your turn.

No, I understand that perfectly.  But this advice:
QuoteThe most important aspect of cornering is vision.  Look as far into the corner as you can.  The slower you are going, the farther you'll have to turn your head because the radius of your turn will increase.

If you increase your speed, the radius of your turn will also increase at the same rate.  If you look as far as you can through a turn, the bike will follow.
Doesn't make sense to me.  Regardless of how fast you are going, and how much you lean to make the turn, you should be taking about the same path at any speed, with the same radius, and looking all the way through the turn the same way.

Okay, I'm reviving this because I found a quote from a riding instructor that explains this much better than I was able to.

Andy Morrison is a 53 year old riding instructor with 37 years of experience.  He teaches at the Rapid Skills riding school in bloody England.  It sounds even better if you read it with a fake accent.

He wrote:

Steering with the Trottle:
"It's not really directly to do with the trottle," says Andy Morrison.  "Look at modern-bikes - they're bred for acceleration, they're really, really good at it.  Say you're riding at 50 mph - you add 30 mph to that very quickly.  It's the change of speed that changes your line.  If you double your speed, you quadruple your braking distance because you've quadrupled the amount of energy in the bike.  Cornering is the same. At full lean at 30 mph you'll get a certain turning circle.  Double that and you'll get a circle four times bigger, and because the bike's so quick at changing speed, you can go from one to the other in just a few moments."

I actually went out and did this the other day.  I started off doing really slow speed u-turns with the bike leaned way the heck over and counter balanced.  Then I kept it at the same lean angle and started adding speed.  I slid my weight by over the bike and kept it leaned all the way over eventually and by time I was going 30 mph I was doing a huge cirle.  I couldn't turn it tighter if I tried.  You should try this.  It is a really good drill.  You learn a lot about lean angle and really can get a feel for what the front tire is doing. 

I'll be scrapping pegs in to time at all.  Hope that is more clear.

To all peg scrapers. (Like me.)

Just remember road rash hurts at first, but when the Alcohol goes on to sterilize it, that's what realllllllllyyy hurts. (The kind of hurt where you curse out the person cleaning your wound.)

I'm cleaning it right now..... Let me tell you, it sucks.

The wheels are supposed to stay on the road when you scrape your pegs.

Altephor

I think he's saying watch the f*** out if you're scraping hard parts, or else you might be scraping YOUR parts.

Exactly, and there's no retailer I know of that has replacements for those, oh and BTW, my road rash says....
