The Honda CBR1000RR was developed by the same team that was behind the MotoGP series. Many of the new technologies introduced in the Honda CBR600RR, a direct descendant of the RC211V, were used in the new CBR1000RR such as a lengthy swingarm, Unit Pro-Link rear suspension, and Dual Stage Fuel Injection System (DSFI).
The seventh-generation RR (SC57), the Honda CBR1000RR, was the successor to the 2002 CBR954RR. While evolving the CBR954RR design, few parts were carried over to the CBR1000RR. The compact 998 cc (60.9 cu in) in-line four was a new design, with different bore and stroke dimensions, race-inspired cassette-type six-speed gearbox, all-new ECU-controlled ram-air system, dual-stage fuel injection, and center-up exhaust with a new computer-controlled butterfly valve. The chassis was likewise all-new, including an organic-style aluminum frame composed of Gravity Die-Cast main sections and Fine Die-Cast steering head structure, inverted fork, Unit Pro-Link rear suspension, radial-mounted front brakes, and a centrally located fuel tank hidden under a faux cover. Additionally, the Honda Electronic Steering Damper (HESD) debuted as an industry first system which aimed to improve stability and help eliminate head shake while automatically adjusting for high and low speed steering effort.
A longer swingarm acted as a longer lever arm in the rear suspension for superior traction under acceleration and more progressive suspension action. Longer than the corresponding unit on the CBR954RR (585 mm (23.0 in) compared to 551 mm (21.7 in)) the CBR1000RR's 34 mm (1.3 in) longer swingarm made up 41.6 percent of its total wheelbase. The CBR1000RR's wheelbase also increased, measuring 1,405 mm (55.3 in); a 5 mm (0.20 in) increase over the 954.
Accommodating the longer swingarm was another reason the CBR1000RR power plant shared nothing with the 954. Shortening the engine compared to the 954 meant rejecting the conventional in-line layout. Instead, engineers positioned the CBR1000RR's crankshaft, main shaft and countershaft in a triangulated configuration, with the countershaft located below the main shaft, dramatically shortening the engine front to back, and moving the swingarm pivot closer to the crankshaft. This configuration was first successfully introduced by Yamaha with the YZF-R1 model in 1998 and inspired superbike design in the following years.
Chassis/Suspension· Lightweight twin-spar extruded aluminum frame features a pivotless swingarm design utilizing a cast aluminum bracket attached to the swingarm pivots. This combination provides an exceptionally light, tuned-flex design offering superb road feel and excellent rigidity.· Tapered and braced box-section swingarm provides exceptional lateral and torsional rigidity.· A cast aluminum bracket reaches underneath the swingarm and attaches to the swingarm pivots, forming a D-shape swingarm mounting enclosure that increases the rigidity of the swingarm-to-engine mounting.· 43mm inverted aluminum-slider Honda Multi-Action System(tm) HMAS(tm) cartridge fork features spring preload, rebound and compression damping adjustability, and offers precise action and unparalleled rigidity.· Pro-Link(r) rear suspension features a high-quality HMAS damper with an integrally cast reservoir, 13-position spring preload, rebound damping and compression damping adjustability for superior rear wheel control.· Braking system features huge, 330mm front floating discs with four-piston calipers and a 220mm rear disc with a single-piston caliper for exceptional stopping power.· Super-light aluminum-alloy hollow-spoke wheels feature race-spec 3.5 x 17-inch front and 6.0 x 17-inch rear dimensions. 2b1af7f3a8
