Is the honda cbr 500 a good first bike and how expensive is the insurance and cost?

Ok i'm 20 ans iv always wanted to ride a motorcycle ever since i was little and now i have a full time job and want to ride. I heard about the 250s but i know that id be tired of it after like 4 to 5 months while riding. I was thinking of the honda cbr500 i'm 5'9 155 pounds. Also how much would insurance cost and the paynents per month i may put 1000 down but i'm not sure i just want to have a decent amount of pay per month not too much

What you actually don't know is going to hurt you

It's a bit big.
I just love all these guys who KNOW they will get tired of something they haven't even tried yet.

Cost of the bike depends on if you buy new, used or finance.
Can't even guess without details.
Cost of the insurance will vary depending on many factors:
Age, marital status, experience, size and type of bike (if financed), ZIP code… Only an agent can give a reliable guess.

My bike payments are zero.
My insurance costs me about a dollar a day (and I pay extra by paying monthly).
