January 20, 2005-Honda Motor Co., Ltd. has announced a full model change for CBR600RR super sport bike, which incorporates advanced technologies inherited from Honda's RC211V^*1racing machine. The new model goes on sale Thursday, January 27.

The new model has been significantly lightened, especially in the main frame, for a weight saving of 5.6kg. Heavy components have also been moved closer to the center of gravity to attain a higher concentration of mass, achieving a major improvement in handling performance and high operating stability.

For the new model, the shape of the inlet port has been modified and the length of the muffler and exhaust pipe reworked to ensure a more linear throttle response in the mid-speed range. Fuel injector settings were also adjusted to achieve greater combustion efficiency. The previous model's PGM-DSFI settings were changed to go along with the modified inlet port shape, enabling stable, high-efficiency combustion over the full range of engine rpms to achieve optimum output characteristics.

The suspension incorporates an inverted front fork for greater rigidity, which works together with a lighter version of the popular Pro Link suspension in the rear unit to help make the bike more manageable. The front brake is equipped with the same high-rigidity radial-mount calipers as are used in the RC211V and the CBR1000RR, to ensure effective braking with outstanding control.

The bike’s styling incorporates the latest RC211V design, with changes to the shapes of the windscreen and air intake ducts. The seat cowl features slim styling for minimum air
resistance.

For coloring, two new colors—Black and Force Silver Metallic—have been added to the current Italian Red, for three colors in all. Since it was first introduced in July 2003, the CBR600RR’s stable ride and high potential has earned it a reputation for comfortable riding performance on the street. A full range of amenities including HISS^*2 and multi-function instrument panel have further added to this model’s popularity.

No effort was spared to make the CBR600RR's frame and other components as light as possible. Advancements in hollow-core fine die-cast production technology for the main frame allowed the frame walls to be made physically thinner while maintaining rigidity. Around 65% of the bike's parts were reassessed and changes made to the muffler production process, muffler protector construction, swing arm construction, and in other areas, resulting in a significant weight saving of 5.6kg over the previous model. The seat rail was also lightened to attain a higher concentration of mass, achieving a major improvement in driving performance and more nimble handling.

The suspension employs 41mm-diameter inverted front forks for increased front-end rigidity, resulting in more precise control and dependable handling. The brakes employ the same radial-mount calipers as are used in the RC211V and the CBR1000RR. This ensures greater caliper rigidity during braking, ensuring even force distribution over the entire brake pad surface for effective braking control.

The CBR600RR, which incorporates various advanced technologies from the constantly evolving RC211V, also adopts the RC211V's design concept of functional beauty.
The shape of the windscreen on the front cowl has been changed to adopt the same sharp design as is used in the latest RC211V. The design of the air intake duct has also been modified to further reduce air resistance, while a slimmer shape has been adopted for the tail cowl.
Like the previous model, the new CBR600RR employs a center-up exhaust system for its superior aerodynamic characteristics and concentration of mass near the center of gravity. Even the shape of the exhaust port has been changed from round to oval-an indication of the level of attention Honda has paid right down to the finest detail.

In addition to vivid Italian Red, the CBR600RR now also comes in two new colors-self-composed Force Silver Metallic with a black stripe running along the side and intrepid solid Black-allowing owners to pick a color to suit their taste.
