An all new 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 999 cc (61.0 cu in) 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 claimed power output to be at least 178 hp (133 kW) at 12,000 rpm.
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.
On September 5, 2008, Honda announced the 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 (C-ABS) system originally showcased on the CBR600RR Combined ABS prototype. New, lightweight turn signals were also added.
On September 4, 2009, Honda announced the 2010 model. Honda increased the diameter of the fl
