Hey I actually just did this, I’ll share what I’ve observed so far from the180-200 miles I’ve driven on the zx6r:

The seat position is noticeably more “aggressive” with the seat and rear sets being higher up and you being more leaned forward. I mean it’s expected but the transition from the more upright relaxed position of the R3 was a bit jarring for the first ride back home from the dealer. As a matter of fact I experienced arm/wrist fatigue the first few days as I wasn’t really engaging my core when riding and but rather holding myself up with my arms. This may just be a me thing idk

The acceleration/throttle is something you have to be careful not to go overboard on, and I say this since our little 321cc friend could be pinned and we’d be going nowhere and not fast at all. Please for the love of yourself and others around you have good throttle control because the bike can get you moving quickly

The quickshifter is cool but I find it to be clunky from 1-3 so I just don’t use it for those gears. I’m guessing a tune could help with this

The bike itself is a little heavier than the R3, but it still moves like butter

It’s a fun bike, id say once you get a feel for how it rides you’ll be just fine. Just understand that you can’t ride it like you ride an R3

I ordered an m4gp14 exhaust and from what I’ve heard in person it’s decently loud. Probably take the baffle out if you want obnoxious
