Don't forget to put your feet on the ground when the bike is not moving.
Don't get a bike that is too large for you both in size and power.
My first bike was a Yamaha Virago 500. Then I purchased a Yamaha XT350 street/trail.
I was always scaning traffic when I rode and anticpated that the car next to me was going to cut me off ( happens more than I cared for).
I was military at the time and they required that we wear reflective belts when we rode.
I had a neon yellow/pink/black jacket that I wore also.
Make yourself as visible as possible. Dark colors are harder to see.
Its an enjoyable sport, but avoid the temptation to break the sound barrier.
