Welcome to the forum. The 2016 FJR will be a nice ride! A couple things to know coming from a HD, cruiser like I did.
The FJR loves high revs. You'll think you killing the engine so high, BUT, the bike comes alive at 5k and higher, 7K+ it is a sport bike true and true. And no, your not killing it. She loves it!
Once you start riding it, there is no comparison to the HD. She'll accelerate faster, stop faster (anti-locks) and you will go into leans where you used to scrape, no more. There is a whole nother bike world out there where leans and speed are great. So, you will be on average, going faster and braking harder before you go into turns, throttling harder out of turns... It is just natural. Just don't ride over your head. I know on my 2014 FJR, I am the limiting factor, not her.
And she is fine with that.
