My Valks cruise along at 6-point-plus speeds just fine with their current state of tune.
If I want to go Ridiculous Speed I'll hop on one of my C14s. Ludicrous Speed entails a ZX14. Both of these models have enough braking and maneuverability to safely manage traffic dynamics at very high velocities - and they also fit me better than ANY liter-plus sport bike.
The things the Kawis don't do are to provide voluminous luggage capacity for trips, or give mama a comfortable back seat. Different tools in the tool box.
You're a better man than me. I don't mind saying those bikes scare me. My neighbor, who used to work on my farm as a teen, was nearly killed on a Yamaha R1. He stopped riding altogether. Another friend lost his license after he got caught going 145 mph on his Hayabusa. He later hit a deer on the same bike (probably flying along) and now he rides an adventure bike. And the mechanic who inspects my bike every year said his V-Max tried to kill him twice. He's on a Harley now.
I find my Valk goes just as slow as I want it to. Makes it easier for the other riders to stare at her.
