I'm not a big fan of telling people what they should ride.
Nor am I a proponent of "get a small bike first," assuming they are "easier to handle."
They are not. They may be lighter, however, some of their handling characteristics are atrocious.
After all, did the size of the engine in your first car have that much meaning to you?
The only way to determine what is right for you is to swing a leg over a lot of motorcycles, see if you can get some test rides, and approach people on the sidewalk who get off a motorcycle.
Size doesn't matter.(ladies, please stop laughing......)
(Big inch Harleys, while 700+ pounds, are very docile and easy to handle at parking lot and walking speeds. The "smallest," Harley, the Sportster, is a handful at slow speeds. How do I know? I've ridden them both)
Your weight is immaterial, unless you're considering a 50cc motorcycle, but as you're on BC"sport" bikes, you're considering an "all road," worthy machine.
My recommendation?
Buy something, anything, you think you'll like to ride, and makes for great garage jewellry. Don't spend a lot of money on it. In other words, buy used, for now, and dedicate your efforts and money on proper gear and training. Once you're fully equipped with gear (waterproof gear, you live in Courtney fer cryin' out loud!) and are trained, the motorcycle becomes a tool, and you are better equipped to choose a tool that suits you best.
That worked for me.
The "training and gear first," might work for you too.
