CBR400RR Specifications

Honda CBR400RR

History, Specifications And Technical Information

History

First manufactured in 1988 the Honda CBR400RR, or 'BabyBlade', is the smaller sibling of the Fireblade or CBR900RR series even though it preceded the 900cc Fireblade by several years. It was manufactured for the Japanese home market and from its release stormed straight to the top of the sales charts. The CBR400RR engine was a development from that of the CBR400 Aero, but had gear driven cams, an aluminium frame, a 17 inch front wheel and brand new styling complete with a twin headlamp fairing. It was referred to as either the ‘Tri-Arm’, a reference to its triangulated swingarm, or the NC23, its factory code. This domination of the Tri-Arm was continued in 1990 by the next generation of CBR400RR, the ‘L’ model, also known as the ‘Gull-arm’, or its factory designation the ‘NC29’. In spite of the superficial similarities between the Tri-Arm and the Gull-Arm, the Gull-Arm was in fact a completely new machine whose parts had much in common with the VFR400, including 17 inch wheels, front and rear. The name ‘Gull-Arm’ came from the bikes new swing arm design, derived from the, then, current race design a year after the swing arm was seen on the race track.
When the 900cc FireBlade hit the worlds markets and revolutionised the sports bike market in 1992 the Gull-Arm got the same paintwork and the FireBlade sticker on the fairing. Even though the 400 was the earlier design, it was christened the Baby Blade and went on to become probably the best selling ‘grey import’ in the UK.

The differences I can find between the earlier L and N models and the later R models apart from colour scheme are.

For the R model.. Cartridge forks with rebound damping also rear shock with rebound damping, different 4th gear, side lights in indicators (may be taken off uk bikes), no parking lights in headlamp, front discs pattern changed, exhaust headers thinner, different carbs with restrictors in inlets (marked 94) for 53bhp , various tolerances and fluid levels different, lights always on and different left switchgear, wiring harness different.

The only difference I can see is part number wise between the R & R2 is in the speedo, the only other evevidence is that in the R model owners handbook that it shows a drawing of a 85km/h speedlight fixed into the Speedo. I. have yet to see an actual Speedo with this item. here is a picture of the Speedo from the handbook.

All Known paint codes

The supplementary colour codes above are taken from the fiche and follow the same A,B,C guide as in the fiche. Things to bare in mind before you run off to RS Paints and make a big order is that the codes maybe for a rear number board, pinstripe, something like a gap in the decals or even a decal colour, such as in the rear Honda logo of a type 5. Check the fiche for more detail as the colour details are always marked on the bottom left of a page such as J14 with a Type/ABC format.Some codes and colours maybe repeated in the ABC column this is following the format of the fiche.

NH1 Black
NH105 Matt black (#15-#20)
NH109M Shot silver metallic special
NH193P Pearl Crystal White
NH194MU Heavy Gray Metallic
NH196 Ross White
NH237P Pearl Pure Black
NH293M Light Silver Metallic
NH343P Pearl Sparkle Black
P5M Jockey Blue Metallic
PB184MU Granite Blue Metallic
PB22B Dionysus Blue
R109 Passion Red
R134 Fighting Red
R203M Procyon Red Metallic
2TN110 Granite blue metallic-U/Heavy gray metallic-U

Thanks to vsource and any other party I have borrowed info or pictures from.

I have also managed to find a copy of the 1992 HRC parts manual for the NC29, previously I had only seen the 1994 copy. If any one wants a copy I will scan it in.
