My lean angle indicator on my Yamaha is the patented and 100% reliable toe/tarmac interface system.
Ultra reliable and is operated by the modem link from the right hand to the main ECU in the brain.
When the main brain ECU detects the previously mentioned toe/tarmac interface, there is a red light which flashes in the frontal lobe ECU controlling the vision and a slow and generally controlled alteration (unless there is a tractor coming the other way) of lean angle to a more acceptable level is done to ensure safe corner transit.
If this highly accurate lean angle system is either ignored or disconnected, a rapid uncontrolled disassembly of man and machine generally occurs.
Hope that helps.
This ^ - - is WORD

I remember , many years ago making an almost fatal mistake ,, France , fine morning , full of the joys ,, moving along a rural twisty/ hilly road at a “ Spirited “ pace Honda ST 1300 and getting distracted by checking the rear mirror and doing a double take that there was an ancient bike/ guy boneshaker antique bike right behind me , putting on some more gas then Relooking just before the next sharp bend . When I looked back I had run 2 feet OVER the line - heading for the bonnet of a grey Merc ( drivers eyes looked like saucers) - pull the bike right down onto the road “ DONT LOOK AT IT , LOOK AT THE ESCAPE ROUTE !!
Peg touches down ,and down and more down ,,, there is NO more down left , foot is squashed off onto road ,, bike stand and feck knows what else is down and Grinding ,,,,,,,,, BUT it goes round ,
Dry warm road ,,,, Bridgestone BT 02 tyres ,,,, save us from becoming a bonnet mascot .
Dunno what the lean angle was ,, - well into brown keck numbers I think !
What a Pranny ,
