Racing roots
The CBR600RR was developed from and inspired by the Honda RC211V MotoGP bike. The similar physical appearance of the CBR600RR and RC211V is intentional. Underneath the looks lie MotoGP technologies that were made available for the first time on a production motorcycle such as the Unit Pro-Link rear suspension and Dual Stage Fuel Injection (PGM-DSFI). Both were taken directly from Honda's MotoGP bike. While it's not uncommon for street bikes to utilize racing technology, this was the first time totally new technologies found their way to the production line the same year they made their way to the professional racing grid. The bike receives the "RR" designation for "race replica" because of its emphasis on racing characteristics such as an advanced braced swingarm, center-up exhaust system, and more aggressive riding position. The 2003 model carried over to 2004 technically unchanged, but with new color schemes.
