Lean angles explained.

I thought I was different to all the Tossers on here. Turns out I'm just average.
15%...

Never really looked into this. Interesting. Especially that there seems to be even more contact area at 50° than I would have ever guessed.
Not clear what distinguishes the type of bike from its lean angle? The scooter I get - small wheels, wide profile = less clearance. But surely the others are down to the rider?
Btw, saw your tyre pics in another post. Clearly you're in the GP bike category

Its not a real street fighter ....
Bloody is.... isn't....
It all depends how the detection is done - I assume that the switch on the front brake lever triggers the rear brake operation - so very light touches of the front lever will activate the rear without the front doing anything??????????

Its a package. From steering geometry, to as you say, ground clearance, to wheel sizes.
A touring bike is designed by its very nature to give you a relaxed style of riding. Part of that package will be (again) geometry and of course tyre profile. For a road orientated touring bike, a rider would want a very neutral feel to the steering, so it neither falls in to a corner, or needs to be encouraged into a corner; neutral. So the tyre choice, its profile, the sizes of the wheels .... all designed with that in mind.
A sports bike will be designed to turn quickly. So its geometry will be different (front wheel under neath yer bollocks!), lots of ground clearance, and by choice the tyre profiles will be very different.
Take a look at the tyre below;

The contact patch when upright, is significantly smaller than when its leant on its ear. Thats good for track riding - it'll fall into a corner very quickly, and once there will have a large contact patch.
But this tyre would feel awful on a touring road bike. Because of the extreme profile of the tyre, it would feel (compared to what you're used to - a traditional road going touring tyre..) quite unstable and skittish when upright, and with its small upright contact patch it would react instantly to every hint of overbanding, white paint, cats eyes etc etc ... It would not steer in a nice neutral manner but would drop into a corner like a stone!
This is why I bang on about test riding bikes at your local dealer! Jumping on R1's to RT's to Electra Glides, is great for understanding how and why bike design works, and the feel you then get from geometry, engine design, etc etc ..

Does this help at all I know its on the sports bike but the idea is the same.
You mention tyre profiles , the GS can have so many different profiles from the steep sided PR5 to the more rounded A41 / Tourance Next , interestingly the new TA3 has a steep profile front ( fast steering ) but a more rounded rear , this for some reason works as well as the PR5 , interestingly the Tourance with its more rounded profile and will when right over squirm a bit as the A41 do , the TA3 and the PR5 don't do this.
A chap I ride with finds the A41 front is only good for 1800 2000 ( notice first at around 1500 miles)miles as well as the side wall are low on tread depth and the tyre went off quick. Now uses the TA3 and swears by them.
Foot note : This may not apply to all riding styles ( disclaimer) other styles are allowed.
Weird.

How does it do that, then?
Don't know but im going to see tonight on the centre stand ...garage experiment I feel coming on ,, get some beer first tho..
I mean, how does it know you're going to use the front brake before you actually use it? Bloody clever, eh!
It's magic!
Whatever it is, it allows the rear brake to operate with the lightest of touches from the front brake lever yet requires 6" of rear brake lever travel to do the same thing.
There is some fancy ECU/ABS stuff going on.
My understanding of electronics is the same as Catweazle's.

Thanks but it’s more I enjoy my time on a bike , the BM works for me and rewards everytime I go out . I ride for pleasure which is a luxury as I know some also ride as part of the daily commute etc
The front brake lever has a micro-switch that operates before any front brake pressure is applied??????
Your rear brake lever is obviously much more effective than mine!
Does your back brake keep going soggy like mine?
No, it keeps going soggy like mine.
