Then we agree.

If you "shift" your weight with your hips, you'll end up crossed up, a la Doohan. If you lead with your head, it will pull your upper body inline with your pelvis when you shift.

Look at how Spies leads with his head and upper body, almost pointing his body like a spear:

While not perfectly straight he is pretty damn close to being in line with the bike:

The other thing is pictures lie... the pic with Hayden,the bike is sideways with the tire spinning,you're not going to be in a "perfect body position" at this point. The other pics could be catching the rider in different transition positions as he is shifting his weight into or out of a corner. Not to mention,that in a snapshot you as the viewer are unaware of the upcoming situation,perhaps the rider is in a chicane and can't fully commit his body to the first corner. The only time you will even approach a text book body stance is in a "smooth" or text book corner situation.

He was barrel-chested, so he was putting a lot of weight to the inside of that curve. He had no helmet or leathers on, and was grinning from ear to ear as he accelerated by me. He must have had lessons.

While I was walking the dog this evening, a scooter rider came around a corner with his knee way out and almost hitting the ground. Except his scooter was weaving and scraping. I thought he had a flat tire. Then I looked up from his scooter and saw that his body was leaning the opposite way. His upper body was exactly perpendicular to the ground. Luckily for him there were no parked cars as he swung way out or he would have hit them. He needed lessons.

Perhaps he learned to ride on an older cycle. Back in the early 80s when I was out screaming on my kawasaki triples, you didn't lean to scrap your knee. You put your ass on the inside of the seat so it would actually turn.

It's interesting how taking curves have changed due to the advancements in bike geometry. Having a bike that's similar to yours, I can see doing that, as opposed to taking half your butt off of the seat. I get better corner response by dropping my shoulder than doing anything with my butt or legs.

I'm in south FL...what is this "lean" thing you are talking about? :idk:

There are curves, they're called "on-ramps'!

that was a point i was going to make as well. Bike has alot to do with it. now a days, sports bikes are more consistent with their "tuned flex" so techniques can be more universal. case in point, those 2 pics of doohan, older bike vs new bike

That makes baby Jesus cry.

This thread makes me smile... in the street section. :panic:

Kickin' it old skool?? Like this guy, raced AMA in the 80's - can you tell from the leathers??

By hanging off and shifting your weight into a turn you're able to go around a corner with less lean angle. There's tons of articles on this. Maybe you should pick up a copy of "a twist of the wrist".

The moped was probably counter weighing that thing. I think the ONLY time this would be useful is for real tight U-turns or just navigating thru a tight spot while going REAL SLOW...that's about it.
