Hi, go to your local Harley Davidson/Buell dealership and take a look that the Buell Blast. The Buell Blast is available with two seat heights for adjustability. The Blast has a 500cc single cylinder engine with a 5 speed transmission. It is perfect for someone with your stature. The Blast is super easy to manuver and it gets 70+ miles per gallon. The dealerships use the Buell Blast for their motorcycle riding course program. If you do not know how to ride and operate a motorcycle, I would look for a MSF (motorcycle safety foundation) course in your area. The MSF course is free if you pass. All you have to do is show up, read the book, ride and pass. Best of luck.
