As an owner of an F, I agree with the review. It is a super fun little bike. It absolutely can do the freeways at nearly any speed, it's just not at home there. I get pushed around in the disturbed air. In clean air, the bike is smooth as butter as fast as you want up to a top speed of 117 mph. Two lane roads and highways are so great though! Plus, even with my fat butt, I avg 65 mpg and get nearly 75 on day rides away from the traffic and stop lights.
This is the same frame, drive train and motor as in the CB500X, and that little Bulldog concept. I'm a fan.
