Substantially lighter than before, and more powerful than ever! Boasting the world's lightest and most-compact inline-four 600cc engine, the new CBR600RR combines radical performance with everyday practicality in a way that'll blow your socks off. With most 600s, you get either a great track bike that's high-strung and uncomfortable on the street, or a great streetbike that lacks the right stuff for track days or race wins. With the CBR600RR, we found a way to achieve superior track and street performance in one amazing bike. Faster than ever for racing, the CBR is also more balanced and predictable for uncanny control on twisty roads or streets.
