The Honda CBR600RR is a 599 cc (36.6 cu in) sport bike made by Honda since 2003, part of the CBR series. The CBR600RR was marketed as Honda's top-of-the-line middleweight sport bike, succeeding the 2002 Supersport World Champion 2001–2006 CBR600F4i, which was then repositioned as the tamer, more street-oriented sport bike behind the technically more advanced and uncompromising race-replica CBR600RR. It carried the Supersport World Championship winning streak into 2003, and on through 2008, and won in 2010 and 2014.
Honda's previous 600-class sport bike, the CBR600F4i, was considered a balance of practicality and performance, as capable as other Supersport-racing 600s, but a more docile and comfortable street bike relative to the competing Kawasaki Ninja ZX-6R, Suzuki GSX-R600, and Yamaha YZF-R6.When introduced in 1999, the CBR600F "fought off racier contenders on the track while still managing to be a more practical streetbike", as described by Motorcyclist, "one golf club that acts like a whole bag."With the successor 2003 CBR600RR, Honda shifted to a more aggressive, less compromising strategy in the "churning dogfight that was the middleweight class at the time", Honda's CBR-RR Project Leader Hiroyuki Ito said, "We developed the RR in a completely different way from any model in the past. In the past Honda has always developed a roadbike, then modified it for racing. But with the RR, we first built a prototype racer, then gave it to the production department."Rotating an aging model down to the next tier of a product line as it is overshadowed by a model with the latest technology is common practice among sport bike manufacturers including Buell, Ducati, Honda, Kawasaki, Suzuki, Triumph, and Yamaha.[
