most newer cars will not start without having a battery, has to do with getting fuel pressure to the injectors and power to the onboard computer, once running most cars will run without the battery, but the charging system is different for a motorcycle, not sure if the newer bikes will run without it (the older ones without fuel injection would).
I am sure the same principals would apply to a bike as a car, but then again I am no expert, BUT I did stay at a Holiday Inn last night.
I heard the Vic's run like crap just having the battery terminals be a little loose ... Or even a weak battery . If they do not like those simple problems , I cant imagine it being too happy with no battery .....
