I don't know if this is great, but definitely insane

Theres one with a cr500 engne in. I think the video is on here or was on the old place. Like you say, totally insane!

*edit* found it!

Deathwish, both of them.

Jarno style clipons on the old triple. Proper proddy racing.

George needs to get down that low to stop M. Marquez getting under him.

Is that from one of your 'tight manoeuvres in a car park' sessions Hoss?

Almost

This is one of mine

I was going to post that Jorge picture for Horse for his "look where you want to go" collection

I was almost too scared to look at the photo ...

There's a decent explanation on YouTube for the reason of the insane looking body positions of modern Gp riders as per Jorge above. It's not so much about moving the rider weight so the bike can remain as upright as possible, but more that the riders are counteracting the negative impacts created by the aero in the corners.
Possibly everyone else already knows this but it was news to me and quite interesting.

I'm guessing it is this one




As it happens, I was wondering about this not that long ago - it was pretty obvious that as the wing angle changes, so does the aerodynamic force - that's why planes don't (usually) bank at 90 degrees, since there's no longer any lift from the wing holding the plane in the sky. There's a B52 crash which happens just like this when an experienced pilot tries a too-steeply banked turn at low altitude - the plane simply noses down into the ground.

Aha. How do planes fly upside down?

Probably something to do with the wing design, angle of attack, use of flaps/ailerons. Stuff like that I suspect.

Badly.

AFAIK the aerofoil of your average plane wing is designed to produce optimum lift right way up, so you can't simply turn it upside down and expect it to fly. However, there are control surfaces which disrupt or enhance lift.

Stunt planes have - and I'm sure someone will correct me - aerofoil surfaces which are closer to symmetrical.

Lancaster Bombers could do it apparently

This is what happens when a B52 banks too steeply.
