If you are just using it for a commuter, you dont need anything flash, as said a 600cc will do fine, ive had alot of bikes mostly fast 2 strokes and lost my licence alot, they are just too dam quick, I now ride a yamahaha 650 vstar, I went for a cruiser because they are good and grunty and this one is shaft drive (I got sick of checking/changing chains) but top speed lets me keep my licence and it looks good, there are so many different types/sizes you can spend alot of time just looking and you have to decide what type you want (commuter, race, cruiser etc) and remember that most car drivers cause bike accidents SO BE AWARE and wear leathers, They do scrub the gravel out with a stiff brush and yes it does hurt.
