What would be a good sport bike for me?

[vigalz11]

I'm 4'11 and weight 100 pounds I had ninja 250 and it was lowered by 2" but i still tiptoeing. I didnt like it because It wasnt fast enough (i drove mostly in highway). Im considering to get cbr 600 but don't know how heavy it is and if they are able to lower it more than 2". Or maybe ninja 300? But I'm not sure if it will make any difference with 250. Please I need suggestion!
Btw I'm a responsible driver and I'm not intent to race with somebody.
Thanks!

You want the MOTORCYCLE section.

Under 5 ft tall you want a bicycle with 24" wheels.
