There are apps that measure lean angle And noting wrong with being off the rear tyre, off the front mind you....
Yeah - I found one on the google app store....works but quite slow....do I start some interesting/pointless threads or what!
In real terms, with modern tyres on a clean dry road you can keep leaning until something starts dragging the floor. But not even traction control will save you if you lean too much, too fast on a wet manhole cover. That's what makes bikes so involving to ride i think and why i love them so.
The Nokia one is really fast....plus if it comes off the bike then that's ok....its my work phone....
Heh....well...as I said - I don't get to go out that often (RSV has been in the garage for the last 3 months or so on the optimate) - just waiting for a dry day....supercorsa's are scary in the wet. And I might add that the last bit of regular use was to work to turn the engine over....so, they tend to square off so when I start to exercise it a little its like its "falling over" as it goes over the squared off bit....hence the need for tyres im quite sure before the TT..!
Your apps might well measure angles whilst stationary but they would not measure angles accurately whilst being accelerated or moving in an arc. This is a physical impossibility with a single accelerometer.
Think what happens in an aeroplane as it banks into a coordinated turn, you don't fall against the person in the seat next to you.
Agreed they are crude, but there is a Pirelli app for track use that is quite good. A mate has it on his iphone and when you get going, it recognises the track from a list, and tracks laptimes, a gauge of lean angle and speed all the way around the lap. Like basic telemetry would. It's better than that crappy DDA software from Ducati, but as people have said, I wouldn't rely on if for real accuracy - it probably just uses an algorithm to simplify lean angle.....but it's quite good fun nonetheless. Use you knee as a gauge of lean angle - that's what it's for! And on the road, if you are getting your knee down (without really hanging off), then you are riding too quickly really, and are likely to come a cropper in due course - the road surfaces and visibility is really not there for that kind of carry on. I also like to know that I have some tyre left. Knee down on the street for me, with my body position, leaves maybe 8mm of tyre left on the side of the tyre (on a 190/200 section tyre - obviously 5-6mm on a 180 and it would be none on a smaller tyre). Handy to know you have plenty more if you need it..... (range rover coming on your side of the road etc.....)
Was thinking the same (only less scientific) as surely the movement/sideways force would stop the angle from 'leaning' just as if you swing a bucket full of water around the water doesn't fall out even when upside down. Alternatively you could try speeding/wheelying past a 'waiting' Police car and then get them to show you the onboard video of the pursuit... :wink:
You could measure the angle of lean by finding the magic numbers between Gs and actual speed? Obviously as you are in a plane you are held in place by the g-force, which increases and decreases in line with the speed and tightness of the turn. So you would only need to measure G-force from a fixed point on the bike towards point of contact on the ground and the real speed to work out the lean angle? I'm not a scientist so I might be completely wrong but it doesn't sound to me like you need to measure force in more than one direction?
You dont have a clue about how a tyre works do you? Deflection? Road camber? Yes your talking shite. It is entertaining at least, so please continue.
But at least by asking, he's learning n'est pas ? That can only be a good thing....as long as we don't rip the hope completely from his heart, a little is entertaining though!
