Honda Grom A Good Beginner Sportsbike?

I'm gonna just drive around town no more then 45 mph, I'm 21.

How fast can 150 cc go

Everything about the Grom you want to know: http://www.hondagrom.net/forums/forum.php

I have a Vespa LX150, 11.7 bhp peak, do a hair over 65 mph actual, 72 mph indicated.
A Grom is a 125, about 9 bhp peak, and 60 mph actual will be easy, more if you get down.

A Grom will out accelerate my scooter.
