Thanks!
I know that the ZX6 is a different type of beast entirely.
But what got my attention was that my old 2006 WR250F had much more grunt from jump. But as was mentioned already; it is deceptive. I was hitting 70km/h after a few seconds.

Maybe it could also be me: I have zero fears when it comes to riding the WR. I could take off at 4-6000 RPM. I used to ring its neck.
Maybe this will be a beast if I give it more of a hit!

I'm not a speed rider anymore. I do need the bike to squirt and rip when needed. But I'm too old for that high speed s**t. Too many stupid things done. Time to come home alive every day!
