The Honda CBR600RR was a sports bike part of the CBR series made by the Japanese motorcycle manufacturer in 2003 and marketed as Honda's top-of-the-line middleweight sports bike that succeeded the 2002 Supersport World Champion CBR600F4i.
The 2003 CBR was based on MotoGP technology used by the Honda RC211V racing machine and featured a similar appearance. The bike was the first Honda motorcycle that featured a Unit Pro-Link rear suspension, a version of the single rear shock absorber with the upper mount connected to the swingarm to isolate unwanted forces transmitted to the steering head.
For the frame, Honda used the new Hollow Fine Die-Cast frame technology, with casting molds that were given a ceramic interior coating, which made it possible to reduce the thickness of the five-piece aluminum frame from 3.5 mm to 2.5 mm.
As for the power department, the 2003 Honda CBR600RR motorcycle was powered by a 599cc four-stroke four-cylinder liquid-cooled engine, which was the first unit that featured Honda's Dual Stage Fuel Injection (DSFI) system, delivering an output power of 117 hp with a peak at 13,000 rpm and 64 Nm (47 lb-ft) of torque available at 11,000 rpm.
In addition, the bike featured a great ergonomic design for maximum rider comfort and minimum fatigue, a more compact instrument panel, attractive hollow three-spoke aluminum wheels, an optional seat cowl, folding aerodynamic mirrors, and a storage compartment under the seat.
