This should be a good bike for you. The seat is a little high at 30.5 inches. I would go to a dealer and sit on one.
Best if you can sit and put both feet flat on the ground. With a seat too high, you will only be able to put one foot on the ground. You may be forced to lean the bike to the side and can easily lose your balance and drop the bike. This could be dangerous in traffic. At the very least, it will be embarrassing. This could also be a problem when you take your motorcycle license road test.
There are lowering kits available for some bikes, but these can cause problems. They change the suspension geometry and can cause handling problems. The reduced ground clearance can cause the bike to drag the pavement in corners, which can cause loss of control. The lower suspension can cause the tire to rub the fender. The kick stand will need to be altered. You can also lower the seat height a little bit by shaving some of the cushion from the seat. However, this can cause comfort issues, especially on longer rides.
