Interested in 70's motorcycles, afraid Im to short??

I want to buy a motorcycle and I really like the look of the 1977 kawasaki kz400, or really anything with that body style. I am only 5'1 and am a little unsure if it will be to tall or to big for me, to handle. I havent rode in over 15 years and really want to start back. Any info about this bike or others with similar body style would be great.
