The most insane riding i've ever seen, period. Total nutters!

[Maki]

The guy with the camera (first vid) seems to come into a couple of corners with the clutch disengaged....yes? Not for me, that...

That is an interesting comment. May I ask what is wrong with coming into corners with the clutch disengaged?

Do you really need to ask why ????

Just look at the eratic movement of the video bike when he does it, I gave up counting the times he got lost in the gearbox. He was suffering from target fixation and not referancing his lines well at all.

With regard to cornering, of the total contact patch your tyres make with the ground, you want the front tyre contact patch to be 40% of the total, and the rear to make up 60% of the total contact patch.
To achieve this you need 0.1G to 0.2G of acceleration, which is usually gentle throttle.

Also of note, is that as you enter a corner you do so by opposing the gyroscopic effect of the front tyre. Once in the corner you mostly oppose the gyroscopic effect of the rear tyre (yes - the rear tyre provides more of the cornering effect once you are actually in the corner).

Throttling off, or engaging the clutch, will shrink your rear contact patch. This will reduce both your traction, and while in the corner, reduce your ability to counter balance and turn.

I can recommend Keith Code's Twist of the Wrist I & II, and the Soft Science of Road Racing if you want further information explaining corner technique, and in particular why you need to apply gentle throttle while cornering.

EDIT: Oops, you said dis-engaging the clutch. So if you are meaning to enter the corner with power applied, I agree.

Goes to show that being a fast rider doesn't automatically mean being a good rider.

A very technical description, which actually makes very little sense in a fast riding situation.

Not many corners I've ever accelerated in to to be honest......

So you don't notice the difference between a trailing throttle or a neutral throttle or starting to crack on the gas while going through a corner...???

Yep, I'm with you ol Trashy.

That camera guy is fuckin hopeless! What a horrible ride!!! Glad they're not on NZ roads.

This is more obvious on a sports tyre - but you'll notice how a motorbike tyre is curved. The outer edge of the tyre was a smaller circumference than the middle of the tyre.

So if you keep the engine RPM exactly the same and lean your bike over, it will slow down (your now riding on a "smaller" part of the tyre).
Conversely if you go enter the corner and lean over without slowing down then your RPM's have to drop.

So normally you would have already brought your bike to the correct entry speed for the corner before entering it. So if you want to prevent your bike from slowing down further (which makes it more difficult to start leaning) you have to apply positive throttle.
You may find you are already doing this but don't realise it.

If you want to scrub off speed in the corner you can keep the throttle on, just don't increase the revs.

But for the reasons described previously, closing the throttle or engaging the clutch so there is no power to the rear wheel will both reduce your traction and your ability to corner.

Dunno what kind if tyres are on your bike but my revs increase when tipping into a corner.

Any chance you are applying positive throttle - like your meant to be, but maybe don't realise you are? A bit like counter balancing?

Of course Im applying a positive throttle...not gunna corner very well if not. If you go into a corner without slowing down how do your revs drop??

Sorry, it's usually best not to try and bullshit a bullshitter.

When riding fast, be it a track or elsewhere, I find myself braking/decellerating almost right up to the apex. I'm pretty sure my bike can decrease its speed more rapidly than the extra 25rpm of engine speed it picks up through the decreased radius of the edge of the tyre.

The notion that someone would try to exactly match their throttle position to the engine revs, therefore accelerating to maintain a set speed means that that person is spending 9 of their 10 dollars on concentration on an unimportant task is downright dangerous. If you actually DO THIS, you're a peanut and will one day run out of road without realizing it.

Zero chance. My throttle is closed, I'm changing down gears and my front brake is applied. You suggest I should throw an open throttle in the mix to REALLY fuck the balance up?

When I'm exiting, yeah sure I've got some throttle on. Usually more and more as the bike stands up. But entering it, no.
