The CBR 600RR was introduced in 2003 as race replica alternative to Honda's more street oriented 600-class sport bike, the CBR 600F4i. It was based on technologies used in the Honda RC 211V Moto GP bike, and was given a similar appearance.It was the first Honda to use Unit Pro-Link rear suspension and Dual Stage Fuel Injection (PGM-DSFI), both were taken directly from Honda's Moto GP bike.PP Tuning performance parts for CBR 600RR (rearsets, adjustable brake and clutch levers, clip-on handlebars, protectors etc.) are produced from highly resistant materials. This ensures their longevity.
