Plunk your butt on it. My girlfriend has one. She’s 5’10” and it’s pretty small for her. If I sit on it at 6’6″ my knees are up over the gas tank. I have a feeling it’s probably going to be borderline ridiculous on you.
It made a great bike for her first season of riding. It’s light, it’s narrow through the middle, it’s very low powered (even though it’s a 652cc bike it only puts out something like 34hp and 30-something ft/lbs of torque). I even took it to work a few times as she isn’t a fan of going out in anything but 75 F weather. It didn’t seem to want to do anything above 73mph on the high way. Thats fine for getting around, but I’m not sure I would venture any sort of long trip with it, especially not on the highway as it is way too light for comfort.
All in all it’s a fun bike though, there is only one thing that I would say is truely bad about it… it sounds like an old toro lawn mower. The single cylinder “thumper” really doesn’t sound anything like what you would think a motorcycle would sound like.
