Honda CBR1000RR Fireblade SC57 998cc 2004-2007 Service Manual

Honda handed the CBR1000RR project to the same engineering team behind its MotoGP effort, and it shows in how comprehensively the SC57 broke from its CBR954RR predecessor. Despite evolving the Fireblade lineage that started with the CBR900RR back in 1992, few actual parts carried over — this was a genuine ground-up redesign built around Honda's "Total Control" philosophy: centralizing mass near the bike's center of gravity so a liter-class engine could still handle with the agility of a smaller-displacement machine.

Power comes from a compact 998cc liquid-cooled inline-four, DOHC with 16 valves, delivering a claimed 172 hp at 11,250 rpm and roughly 85 lb-ft of torque at 10,000 rpm, run through a race-inspired cassette-type close-ratio 6-speed gearbox — a design that lets mechanics swap gear ratios without splitting the crankcases, borrowed directly from CBR600RR development. An all-new ECU-controlled ram-air system, dual-stage fuel injection, and a center-up exhaust with a computer-controlled butterfly valve rounded out the powertrain, while a 43mm inverted HMAS cartridge fork offered full adjustability for spring preload, rebound, and compression damping.

Weight reduction was aggressive and deliberate: titanium valves, magnesium engine covers, a lightweight aluminum frame, and hollow axles brought dry weight down to around 370 lbs, a substantial cut from the CBR954RR's 388 lbs. 2006 brought a meaningful mid-cycle update: Unit Pro-Link rear suspension replaced the original Pro-Link design, along with revised chassis geometry that sharpened front-end feedback, plus a suite of detail refinements based on rider feedback. Top speed sits around 177-180 mph depending on test conditions.
