First Generation (1992-1993)Edit

1992 Honda Fireblade.

Developed by Tabao Bada, the Fireblade was designed to be a light weight performance superbike. It features a 893 cc inline-four engine with the weight of 453 lb (205 kg) with a full tank. 







Second Generation (1994-1995)Edit

Numerous changes were made to the second-generation RR, which debuted in 1994, including revised spring and damping rates, a compression adjuster was added to the front fork, an improved shift drum to cure notchy shifting, the upper cowl stay went from steel to aluminum, and the cylinder

head cover went from aluminum to magnesium. The styling of the bike also became more aggressive: The independent dual lights became irregular-shaped multi-reflector lights known as "tiger eyes" and the bike now featured fewer of the RR's unique fairing holes. In addition, slimmer and firmer footpegs were patterned after the RC45
 and a shift linkage replaced the original model's backward pedal. A new instrument panel included an electronic speedometer that measured speed from the countershaft sprocket, rather than the front wheel.


Third Generation (1996-1997)Edit

1996 brought the first major changes to what was now the third generation of the CBR900RR. In order to achieve a more optimized balance of rigidity, Honda significantly altered the 1996 CBR's chassis and suspension. The frame and swingarm were fabricated from larger, thinner-walled extrusions for increased torsional rigidity. The fork and shock internals were re-designed, and the swingarm pivot raised by 5 mm (0.2 in). Revised ergonomics brought the bars 10 mm (0.4 in) higher and swept back five degrees more than earlier models, along with a slimmer gas tank. Engine updates included a bump in displacement to 918 cc (56.0 cu in) via a 1 mm (0.039 in) bore increase, slightly higher compression, a curved radiator, larger exhaust, extra clutch plates, smaller alternator, and the addition of a throttle position sensor. The 1996 model carried over to 1997 unchanged except for the updates to color/graphics offerings.


Fouth Generation (1998-1999)Edit

In 1998, Honda continued subtle refinements in the fourth generation CBR900RR's chassis. It saw frame stiffness closer to the original model's, revised suspension internals, and 5 mm (0.2 in) less triple clamp offset (an almost universal aftermarket upgrade to previous models). New brake calipers acted on larger front discs, the fairing was re-shaped and raised footpegs subtly changed ergonomics again. Eighty percent of the engine's internals were all-new to reduce weight and minimize friction; other updates included redesigned combustion chambers and porting, aluminum composite cylinders, new pistons, a smaller and lighter clutch pack, revised gearbox ratios, larger radiator, and a new stainless steel exhaust header.

Fifth Generation (2000-2001)Edit

The fifth generation of RR, known as the CBR929RR in North America, was introduced in 2000 and had a completely new 929 cc (56.7 cu in) engine incorporating fuel injection, more oversquare cylinder dimensions, larger valves set at a narrower included angle, lighter internals, and an all-titanium, HTEV-equipped exhaust system. The "pivotless" chassis had the swingarm mounted to the engine cases but incorporated a brace underneath the engine. Updated suspension and brakes included an inverted front fork and 320 mm front discs; and the 16 inch front wheel was replaced with a more common 17 inch wheel.


Sixth Generation (2002-2003)Edit

2002 Honda Fireblade.

The sixth generation of the RR was introduced in 2002 (known as the CBR954RR in North America and Japan), cylinder bore was increased from 74mm to 75mm, increasing capacity to 954 cc (58.2 cu in). Larger fuel injectors and radiator, re-mapped electronic fuel injection, and a more powerful ECU were also added. The bodyworks and fairings were reworked for a sleeker, more streamlined feel. The frame was strengthened and a more rigid swingarm added and the footpegs were raised to allow for greater lean angles. Front discs increased to 330 mm. Dry weight was reduced to 168  kg (370 lb).

The CBR900RR was replaced by an all new CBR1000RR in 2004.
