Sometimes, if you want the best solution, you have to think outside the box. In fact, sometimes it's best if you throw the whole concept of a box away. That's what our engineers did with the CBR650F. Traditional displacement classes went 600-750-1000. But who says you had to stick to that? An extra 50cc is going to make the CBR650F a lot more fun for a lot more riders. It lets us fatten up the powerband, but still keep the bike light and nimble.
