(Redirected from CBR900RR)

The 'Honda CBR900RR' is a large displacement sport bike introduced in 1992 by Honda as the first of the Honda Fireblade models. It was designed by Tadeo Baba.
The CBR 900RR was reputedly introduced with the hope of reigniting bikers' enthusiasm for large capacity sports machines at a time when big bikes were losing ground to smaller displacement counterparts because of lacklustre handling and power delivery problems.
The CBR 900 was originally fitted with an 893cc 4 cylinder inline engine. Its handling capabilities were considered superior for a liter bike at the time, and stemmed from its relatively low weight of 185 kg, good braking and good steering design.

The original Fireblade design was refined and developed over the the following years with the engine capacity increasing with each successive model in the series. In 1995, engine capacity increased to 918 cc (CBR918RR) and the suspension was updated. This model had a reputation of civility toward the driver.
In 2000, engine capacity increased to 929 cc (CBR929RR). Added were Electronic Fuel Injection (EFI), active exhaust, all new USD (upside-down) forks. The swingarm pivot was moved to the back of the engine to reduce frame size and therefore overall mass. Weight trimmed down to 170 kg.
In 2002, engine capacity increased to 954cc (CBR954RR), larger injectors and radiator, re-mapped Electronic Fuel Injection and a more powerful computer were added. The bodywork and fairings were reworked for a sleeker, more aerodynamic feel. The frame was strengthened and a more rigid swingarm added and the riding position/pegs were raised to allow for greater lean angles. Dry weight reduced to 168 kg.
In 2004, Honda produced its first CBR1000RR 998 cc Fireblade, bringing the engine capacity of its sportsbike flagship model up to match that of its major competitors. The first computer-controlled, fully variable steering damper was introduced, along with race-inspired swingarm and rear suspension. Radial Mount front brake calipers were introduced.
