Honda CBR1000RR


The Honda CBR1000RR, marketed in some countries with the Fireblade suffix, is a sport bike produced by Honda since 2004 as the seventh generation of the CBR series|CBR] Fireblade series of motorcycles that began with the CBR900RR in 1992.

History

Racing roots

The Honda CBR1000RR was developed by the same team that was behind the MotoGP series. Many of the new technologies introduced in the CBR600RR were used in the new CBR1000RR such as a lengthy swingarm, Unit Pro-Link rear suspension, and Dual Stage Fuel Injection System.

2004–2005 (SC57)

The seventh-generation RR, 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 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 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 the CBR1000RR's longer swingarm made up 41.6 percent of its total wheelbase. The CBR1000RR's wheelbase also increased, measuring ; a 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.
Positioning this compact engine farther forward in the chassis also increased front-end weight bias, an effective method of making high-powered liter bikes less wheelie prone under hard acceleration. This approach, however, also provided very little space between the engine and front wheel for a large radiator. Engineers solved this problem by giving the RR a modest cylinder incline of 28°, and moving the oil filter from its frontal placement on the 954 to the right side of the 1000RR engine. This allowed the RR's center-up exhaust system to tuck closely to the engine.

2006–2007 (SC57 II)

The eighth generation RR was introduced in 2006 and offered incremental advancements over the earlier model, and less weight. Changes for 2006 included: A revised front fairing design, new rear suspension with new linkage ratios 135 mm, along with a new chassis geometry, and a new lighter swingarm. A new intake and exhaust porting. A higher compression ratio. The cam timing was revised. Intake valve lift was increased from 8.9 mm to 9.1 mm. Double springs for the intake valves were implemented. The engine RPM redline was increased from 11,250rpm to 12,200rpm. A larger rear sprocket was fitted. New exhaust system.
The disk brakes were changed with a larger diameter front brake discs but thinner at as well as a larger rear brake discs but thinner at Along with a smaller, lighter rear caliper.
The 2006 model carried over to the 2007 model year mostly unchanged except for color options.

2008–2011 (SC59)

An all-new ninth-generation RR, the CBR1000RR was introduced at the Paris International Motorcycle Show on September 28, 2007, for the 2008 model year. The CBR1000RR was powered by an all-new inline-four engine with a redline of 13,000 rpm. It had titanium valves and an enlarged bore with a corresponding reduced stroke. The engine had a completely new cylinder block, head configuration, and crankcase with lighter pistons. A new ECU had two separate revised maps sending the fuel and air mixture to be squeezed tight by the 12.3:1 compression ratio. Ram air was fed to an enlarged air box through two revised front scoops located under the headlamps.
Honda made a very focused effort to reduce and centralize overall weight. A lighter, narrower die-cast frame was formed using a new technique which Honda claimed allowed for very thin wall construction and only four castings to be welded together. Almost every part of the new bike was reengineered to reduce weight, including the sidestand, front brake hoses, brake rotors, battery, and wheels.
In order to improve stability under deceleration, a slipper clutch was added, with a center-cam-assist mechanism. The Honda Electronic Steering Damper was revised as well. Another significant change was the exhaust system, which was no longer a center-up underseat design. The new exhaust was a side-slung design in order to increase mass centralization and compactness while mimicking a MotoGP-style.

2009

On September 5, 2008, Honda announced the tenth generation of the RR as a 2009 model. The bike remained much the same, in terms of engine, styling, and performance. The only significant addition was the introduction of the optional factory fitted Combined ABS system originally showcased on the CBR600RR Combined ABS prototype. Lightweight turn signals were also added.

2010

On September 4, 2009, Honda announced the eleventh generation of the RR as a 2010 model. Honda increased the diameter of the flywheel for more inertia. This improved low-rpm torque and smoother running just off idle. The license plate assembly was redesigned for quicker removal when preparing the motorcycle for track use. The muffler cover was also redesigned for improved appearance.

2012–2016 (SC59 II)

The twelfth-generation Fireblade celebrated its 20th anniversary, revised for 2012, featuring Showa's Big Piston suspension technology, Showa balance-free shock, further improved software for the combined ABS, new 12-spoke wheels, aerodynamic tweaks, an all LCD display and other minor updates.

2014

Retuned engine for additional power, modified rider position along with new windscreen. Also added a performance oriented "SP" variant.

2017–2019 (SC77)

For 2017, with the 25th anniversary of the Fireblade, Honda has updated its flagship CBR with new bodywork and features such as throttle-by-wire and traction control for the first time that works with selectable ride modes. A retuned engine which now produces a claimed and at the rear wheel, a 10 hp increase, titanium muffler and a 14 kg weight reduction for a wet weight of. Some of the new features on the SP model are semi-active Öhlins Electronic Control suspension, Brembo monobloc four-piston front brake calipers, titanium fuel tank and a 13:1 compression ratio. Also adding an even more exotic limited production "SP2" variant with Marchesini forged wheels and with larger valves of which 500 units will be sold.

2019

The CBR1000RR Fireblade received some electronic updates for 2019. The traction control is now separated from the wheelie control, meaning both systems can be controlled independently. The dashboard now has a three-position ‘W’ setting, alongside the Power, Engine Braking and Honda Selectable Torque Control traction settings. The ABS settings has also been tweaked, giving less intervention above and giving 15% more deceleration. The ride-by-wire throttle motor is also enhanced, giving the throttle plates more quick reaction to the rider's inputs.

2020–present (CBR1000RR-R; SC82)

For 2020, the CBR1000RR is updated along with an updated name for the SP model which is race inspired, with redesigned bodywork and new engine based on technologies used in RC213V MotoGP bike.

2024

Changes to the 2024 model include improved specifications for each engine part that have resulted in improved acceleration performance in the mid-range, the implementation of Honda's first two-motor throttle-by-wire system, and weight reduction through redesigned frame body components.
