My bike just broke down.

I turned the ignition key, the bubble rises, the light turns on and off, I press the start button ...... it nothing happens.
The bike is at my dealer and diagnostic tool, finds no fault.
I fear that it will be difficult to find the problem

[Bajagrngo]

 Maybe it's the starter switch

[Hervé]

Starter switch, I was thinking the same but i assume the dealer checked that!

Did you tried to switch on the bike without the side stand?
This only because I’ve had an issue with the gear sensor and I had the same issue. When you loock at gear indicator, does it show neutral?

[gus77]

yes
before giving it to the dealer I tried several times to pass a speed and return to neutral
I watched as the contactor side stand to see if it was not blocked and the clutch lever switch
all working correctly 

[seadog]

Could it be the Clutch lever play. ie  not clearing to allow start up.

Just a thought

a small feedback,
My dealer has not found the fault. 
the bike will probably go to France Triumph for disassembly and analysis
I will return as soon as I have information 

[Verdun95]

where is your dealer, Aulnay ?

The dealer couldn't diagnose    Even with a Triumph diagnostic tool   Has to be either incredibly serious or else something so simple that it was overlooked.
