It's not just for appearances, either. Honda has some interesting claims regarding the 600's smoother skin, too. For one, it has 6.5 percent less drag, which presumably contributes to improved fuel economy, up from an estimated 40 mpg to 44. As I rode the 2013 CBR down the 101 freeway on my way to some fun canyons, I noticed a larger pocket of still air in the cockpit. Having ridden a friend's 2012 CBR600RR to the press launch in Simi Valley, CA, I was well acquainted with the previous bike's limited wind protection; move an inch or two to either side of the short windscreen and you're out in the breeze. Not so on the new bike, which has a slightly taller windscreen and wider fairing.
