Seriously ?? What kind of tyres and on what kind of bike ??? What kind of road surface and in what kind of weather? At what time of day and what air and road temperature?

I suspect the maximum lean angle is the one you get just before it falls over ...

Try that slalom bullshit on cold tyres and when you end dumping it on the ground, that should give you some idea of when you have gone to far. So then you'll know for next time.

Most manufacturers specify maximum lean angle in degrees.

I've got mad skillz. The other day I got 100% lean on, l33t. Though that was unintended and technically it's more dropping/falling than leaning... but it had to lean before it could hit the ground? I win!

[schrodingers cat]

Remember to initiate with -2 degrees. Without countersteering you cannot turn.

I think 100% is about maximum. I don't know how to go past 100% anything.

well generally, if you try to find grip using the chicken strip, you are already screwed, at maximum lean, a motorcycle pulls
1 G at 1.1 G you are gone, only a racing tire will allow more than 1.1G

if your instinct is telling you you are at about maximum, then you probably are very close.

I wonder if an electronic warning device could be developed that gives an indication of when approaching a dangerous lean angle. Something like an electronic spirit level that was audible.Already has, it's called traction control.

I made one of those a few years ago (its a bit more complicated than a spirit level btw), an LED bar graph was used instead of audio, as there isn't much you can do if you're about to fall off, and something beeps to tell you that... better to learn you got to 70% on that last corner, and don't bother pushing it any further. Worked ok, but needed a better accelerometer and testing data; well, that, and nobody wanted one either :bleh:

[p.dath]

There is a really famous guy called Hans B Pacejka. In my opinion, one of the world's experts in tyre dynamics. If you Google "Magic Tire Formula" you might learn that he is pretty clued up, and many major tyre manufacturers use his formulas and work when designing their tyres.

Now try and get one of his books, such as "Tire and Vehicle Dynamics", and he works through the maths involved. I'll warn you, it helps if you have a Ph.D in physics or applied mechanics, as it is complicated. I would be happy if I could just read it.

Now skip to the magic tire formula to do with grip, and you'll see it has around 20 input parameters. And from this you can expect a close approximation to the lean angle for the case your looking at.


But if you want a short answer, while the 20 or so input parameters are changing, which they will constantly be in this case, there is no one single answer for the question you asked. And even if you worked out the answer one day through experiments, you can bet the answer will be different the next day.


So the moral of the story is, treat the whole rider machine system with respect until it is warm. :) Actually, just treat it with respect, full stop.

[p.dath]

By dangerous I'm going to assume you mean unrecoverable. And if it has reached that point forget about the indication, you might as well get it to dial 111 instead with your location.

It's like have a "plane stalled" warning in a plane go off as it plummets out of the sky.

I would have thought the motorcycle would reach maximum lean angle after it had crashed and had come to a complete stop lying on its side, and would be "pulling" zero g's ? I'm teasing you. What I'm trying to say is while you are not likely to pull 1G on a motorcycle on the road, I'm not aware of any rule that means it will suddenly fail at 1.1G. If you can get enough weight onto the tyre, and the tyre carcass is strong enough, it may well continue to grip before it explodes from force - and because I haven't seen many motorcycle tyres explode from the force applied to them (apart from defective tyres) it seems unlikely that they would suddenly fail at 1.1G.

The chicken strip is not a defective strip of rubber. It grips like the rest of the tyre although it will change the shape of the tyre's profile. Lets take an extreme case of a sports motorcycle with a performance tyre leaning at around 50.1 degrees - do you think it'll be using the chicken strip near the middle or the extreme outer edge of the tyre completely away from the chicken strip?

Untill the fun police make this sort of rubbish mandatory, hopefully, long after I've given up riding, we will just have to learn to ride using our own skills.

Anyway, being cranked right over in a corner and having a 'beep' go off in your ear, wont change where you are and what your options are.

Have you re-evaluated gyro's recently bogan?

I've thought about hacking something similar together but maybe mounting the LED's in the helmet on the bottom of the visor area.

The rate gyros I tried ages ago were shit, but I probably bought the cheapest. They will always have drift, but would be worth looking into...

Yeh I've started that sort of thing too, but its hard to get the cases right and have it adjust for lighting when its right up in your grill, so I've haven't got back to it.

[varminter]

I have a piece of string with a weight on the end in front of my visor. When the string passes in front of one of my eye's I know to straighten up, not foolproof I know, as I often seem to be climbing out of ditches. Cheap though.

[ducatilover]

I would have thought that would be quite dangerous to keep your eye on while cornering hence why I suggested something audible.

I think I would prefer to rely on my abilities to judge the situatuion and ride to the conditions. The brain is a fantastic thing on the rare occasion it's used.

Not just that, but the time taken to see something, process its meaning, then act is much longer than the time taken to hear something and act.

Navman did a lot of research into this, and if I remember that psyc paper I took to pick up chicks a few years back, it's an area quite widely researched in psych too.

I believe they did tests into the time it took to press a button after a light came on, or a sound played etc or something.

So I would tend to agree, though I think an array of LED's across the bottom of the visor might be out of direct view, and more on a subliminal level, of course I'd have a sound too when you reached the critical zone.

You could even instil some logic into it by allowing it to learn what your average maximum lean angle is

[bogan]

You missed the point, most of the danger is from coming into a corner too hot, fuck all you can do about that half way round the corner if something beeps at you. You can however look at it after the corner, and realise you were at say 70% of available traction, and learn not to push any harder than that.

Just how is any gyro or gizmo going to be able to see the camber at your point in the road? Or the loose gravel, white line ad infinitum. There is no magic lean angle, as said before, that's what your brain with experience sorts out.

Same way your speedo knows that it's raining (it doesn't)

But to answer your question:
Camber can be found with a 2nd gyro or an accelerometer.
white line with an ifra-red diode (see line follower - or not as the case may be)
loose gravel could be tricky, but I'm sure I could think up something.

what you're asking is outside of the spec of what the lean-O-rama tells you, certain assumptions must be made.

This is very true, though there's often a human attached to said eyes and ears and humans have been known to fuck up....I guarantee if motorcycles ever come equipped with this device, it won't completely stop bikes from leaning over too far.

Obviously not, seeing as one dedicates to a corner before max lean is achieved it is an entirely pointless device. Like tits without nipples!

Oh I agree, It'd be nice if we could measure the radius of a corner before we got to it, then we could draw some conclusions from a lean-O-meter, yaw rate vs roll rate etc.

But we can't oh well.

I can think of a track application where you ride around a race track and it logs angles etc, then you come in, analyse the data and the computer says "right you pussy, based on all the info you've given me, you can go faster around all these corners. If you begin rolling earlier, or roll faster here you can go 10% faster at the apex!....etc etc" and you could say "well computer, I can't cause that would mean....etc etc...previous corner....etc"

so also useless.

Sometimes guys like bogan and I like to hack these wee projects together for fun, and wank factor, cause lets face it, driving a bunch of LED's based on a scale from an analogue input isn't nearly as cool mounted to a desk, or a house, or a lamp post amirite?

know what would be cool? hooking up the lean-O-meter to a bunch of RBG LED strips hidden under the fairings etc, so when you rode around at night the ambient glow under the bike changed colour as you leaned in to corners. MAXIMUM WANK.

[ducatilover]

:lol: For wank factor, it's bloody cool. That I can understand.

I do think that it could have a possibly use on the track, but I also think there are too many variables to manage it.
Mine would keep calling me a pussy, that's probably why I don't like it

Time machine, go around the corner, log data whilst crashing, then come back and do it properly :D

Thinking too small, my version would say, "right you pussy, sit your arse down in the pits, I'm going for a hoon without you" :bleh:

that would be cool, and you'd have a big red glow that would make it easy to find in the ditch when you throw it down the road too!

LEDs are bloody neat though, just put 44 into my new headlight (11 control groups)...
