The battery voltage dropping to 11V while cranking is normal i guess. Below 9 / 10 V can be an issue and mean the battery is weak, this is what i've learned over the years. Anyway, it's not an isolated issue on my bike and seems to pretty much happen randomly to many others as far as i've seen.Can we take it that no codes are registered currently?
I see your battery voltage dips down to 11volts, maybe less in the moment, when you hit the starter, which could be where the problem lies. Can I suggest you have the battery tested for CCA capacity. IIRC, the 14S should produce 230CCA. That & checking the terminals are tight/snug would eliminate the battery as the source of the issue.
Then we come back to the decompressor system, that has been mentioned already by @TABASCO. The 11.0:1 compression ratio is reduced to a pressure of 84-108 psi when cranking & rises to around 180-200 psi once running. Clearly if one, or maybe even both decompressors aren't functioning correctly, the starter/battery will have a far tougher job on a cold start.
The bike also had a compression test made recently while doing valve adjustment, with no negative feedback.
Today it started just fine, like 99% of the time.
