My Concours14 has the same engine, although they detuned it a little for touring.
Still, the front tire will get air at 85, and you can break 110 on a short freeway onramp.
I also had it up to 105 on an uphill onramp with a passenger. I had to. I was passing Harleys.
Most of the time, I don't ride like that, obviously. It's just nice to have that kick if you need it.
I'm not sure if the ZX14 is the same, but if you keep it under about 4500rpm, its as mild as a summer breeze. However, pull in the clutch, drop it down a couple of gears, get some rpms, and hang on. It's like a shot off of a flight deck.
Ride safe, my friend.
