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]].

==History==
===CBR900RR===
The CBR900RR was introduced in 1993 and was fitted with an {{convert|893|cc|cuin|abbr=on}} [[inline-4]] engine. When introduced, it set a precedent for light weight in the super bike class. At {{convert|453|lb|kg|abbr=on}} with a full tank of gas, the CBR900RR was just {{convert|4|lb|kg|abbr=on}} heavier than Honda's own [[Honda CBR600F2|CBR600F2]], and {{convert|76|lb|kg|abbr=on}} lighter than the next-lightest open-class machine at the time, the [[Yamaha FZR1000]]. Minor changes to the '94 model included an improved shift drum to cure notchy shifting, and steadier mirrors.

In a move to refine the CBR900RR's handling traits over bumpy pavement, the 1995 model's suspension was upgraded with revised spring and damping rates, and a compression adjuster was added to the front fork. More aggressive bodywork incorporated a "cut reflector" design headlight and fewer of the CBR's unique fairing holes. Slimmer and firmer footpegs were patterned after the [[Honda RC45|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. The only engine change in 1995 was the replacement of the aluminum valve cover with a magnesium piece.

===CBR918RR===

1996 brought the first major changes to 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 reduced torsional rigidity. The fork and shock internals were re-designed, and the swingarm pivot raised by {{convert|5|mm|in|abbr=on}}. Revised ergonomics brought the bars {{convert|10|mm|in|abbr=on}} higher and swept back five degrees more than earlier models, along with a slimmer gas tank. Engine updates included a bump in displacement to {{convert|918|cc|cuin|abbr=on}} via a {{convert|1|mm|in|abbr=on}} bore increase, slightly higher compression, a curved radiator, larger muffler, extra clutch plates, smaller alternator, and the addition of a throttle position sensor. With the revised motorcycle came a revised name of CBR918RR. The 1996 model carried over to 1997 unchanged except for the updates to color/graphics offerings.

In 1998, Honda continued subtle refinements in the CBR918RR's chassis. It saw frame stiffness closer to the original model's, revised suspension internals, and {{convert|5|mm|in|abbr=on}} 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.

===CBR929RR===

A major revision for the open-class Honda resulted in the CBR929RR, aimed squarely at the [[Yamaha YZF-R1]]. A completely new {{convert|929|cc|cuin|abbr=on}} engine incorporated 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 huge {{convert|330|mm|in|abbr=on}} front discs; and the {{convert|16|in|mm|abbr=on}} front wheel was replaced for a more common {{convert|17|in|mm|abbr=on}} wheel.

===CBR954RR===
In 2002, engine capacity increased to {{convert|954|cc|cuin|abbr=on}} which resulted in the CBR954 name. Larger injectors and radiator, re-mapped electronic fuel injection, and a more powerful computer were also added. The [[bodywork]] and [[Motorcycle fairing|fairings]] were reworked for a sleeker, more [[aerodynamic]] feel. The [[Chassis|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 {{convert|168|kg|lb|abbr=on}}.

The CBR954RR would be replaced by an all new [[Honda CBR1000RR|CBR1000RR]] in 2004.
