It's not too bad. Really depends on her weight and if she's ever riden before. The best passenger I ever had was a chick that also had her own sport bike. She would sit up on the highway and hardly hold on. I've had others that would lay all over me and I'd catch myself praying that they'd just fall off.
My advice would be to find a big empty parking lot or a back county road and just ride around for a bit. Remind her to keep her ass on the seat and her shoulders in line with yours and you'll be fine.
Wear your gear and buckle your lid. You'll be just fine.
Nice bike too by the way.
I never thought about the empty parking lot. And thanks, I finally got it fixed back up after a bad wreck last winter
