Speaking with limited experience; "Yeah, the ktrc is that fast"; in F 1, that's exactly what its sposed to do.
My gen 1 ZX 14 would pull wheelies accelerating out of a curve or over a rise and upset my plans. I'd drop off and start over, so to speak, and I found it most annoying; not to mention, I am sure it had a negative effect on my time through that section of the road. I'm also sure an expert rider would not have "choked up" like I did in these circumstances but I am not going to become that skilled at my age and without going to track days, etc. etc.
I love the new ZX for this feature. Now, driving off the same curves, I simply keep the power on and the bike continues to provide huge acceleration while bringing down the front end without "drama". It was spooky at first but certainly not as unsettling as the front end continuing to rise and then after my reactive correction, "bouncing" down hard and skipping a bit side ways! Now, I (Walter Mitty, I admit) can blast out of the curve into the straight like a "second rate" pro; or so I imagine. For sure, I am able to take the same sections of road faster than before and with full control and immense pleasure.
With 1200 miles on the R and regularly visiting the 10,000 + rpm range, I begin to believe that I will never need to or want to turn the ktrc off! If I did stoplight drags for a secondary income, then maybe I would want to master the non-ktrc quarter mile; otherwise, WTF!
BTW, I used the low power/ ktrc 3 setting combo early last month when going on melting snow and icy patch conditions and it definitely made the trip home safer and inspired confidence in the sure footing available for those conditions.
Kinda felt like a tractor and never felt any slip till I applied the brakes a bit too hard for conditions.
