You'll eventually get used to it. You can get mirror extenders or if you like fish-eye mirrors, they can really increase your visibility at short distances. Either way, get in the habit of turning your head. I never trust a mirror (except when backing a trailer). I had too many close calls when I was a young driver and I always turn my head to look before changing lanes or making turns.

Motorcycles give great visibility. You have zero blind spots as long as you turn your head. But on the Ninja, you will have major tunnel vision if you rely only on the mirrors, even with accessories to improve visibility. (In a car tunnel vision is dangerous, on a motorcycle it is deadly)
