Bike died just as I arrived at work (engine trouble warning light)

Oil and fuel are ok.

Just talked with a dealer in Fulham (http://www.yamahaservicecentre.co.uk) who will pick the bike up.

After talking for a few minutes he's thinking it may be the generator (worst case cost incl labour around £850).

There are no error codes displayed, just a bike that died and an orange light that stays on.
