Well my first & only Buell is an 09 Uly XB12X, I think it has 6" of ground clearance with suspension turned all the way up. I am 5"7", 200 lbs, 49 years old. I Love this bike, nothing it cannot do, and I really like the height. Reminds me of when I was a kid when riding other's dirt bikes like a YZ 125. I used to have to climb up on the pegs to get a leg over, I can get a leg over from the ground on the Uly. The seat & bar height gives a great riding posture, for me it's better than a cruiser.
My wife started riding last November, she is close to my age and height. Would Love to see her on a Firebolt. I think that would be a good progression from a GZ 250. She did not grow up with bikes, but has good balance and instinct on one so far. I am super cautious as I have been very lucky as a kid and survived literally unscathed after crashes in the dirt and street, It was pure luck! I hope it is contagious......
