I drive 70-80mph on my commute (except when stuck in traffic), You can wind it past that. It is pretty suprising. I get about 65-70mpg at those speeds too. I would say that the Ninja 250 is an excellent commuter. I have found that by paying attention and expecting the dumbest thing possible will keep you out of trouble and no need for escaping acceleration. I have only experienced on escape with speed situation and that was on the secondaries.
