Just my opinion, but 11.93V is low for a standing voltage, engine off, key off (so no accessory drain.) You usually want to see closer to 12.5V.
According to this: http://modernsurvivalblog.com/altern...-charge-chart/
11.9V is a 40% charge on the battery...
I'd say bad battery.
I have a 1987 FZR1000 that just wouldn't start - battery had 12.3V standing, but no spark when cranking. I checked voltage while cranking and it was (IIRC) 9V while cranking. The old battery just didn't have enough cranking amps to turn the starter and get enough voltage to the coils to get a (good enough) spark on the plugs. New battery and problem solved. So, even a standing voltage test doesn't tell the whole story.
