Griso problems... is it the starter motor?

Don't know for certain, but my guess is that when the starter engages, the battery volts drop very low with the high load, and cause the dash computer to reboot.
 
If you've hooked up a volt meter to it, check the amps should be ~4+, check it when you hit the switch. could have an internal flaw in the battery that passes voltage, but not current. I ran across one of these, didn't fail until the amp draw put the load on, still showed sufficient voltage, but when chanllenged, did not put out sufficient amperage. voltage tickles, amps get your attention
 
Not sure what exactly you mean?

Do NOT try to measure amps with the meter connected across the terminals (as if to measure volts)!!
 
You beat me to it René.

It is true though that you can get a battery which shows good volts at rest, but will not supply a high current. Though usually when trying to supply that high current, the battery volts go down dramatically, possibly causing the dash computer to die for those few seconds.
 
> Though usually when trying to supply that high current, the battery volts go down dramatically

I'd say that's (almost) inevitable (maybe unless the internal resistance is way too high).

Remember, these batteries (see one of my posts above for the reference) are AGM, they can die "like that". Nothing to do but to bleed for a new one, or accept to keep the bike on a tender each time you leave her for a significant time.
