Honda CBR400RR (NC23)

The Honda CBR400RR sports motorcycle model appeared on December 15, 1987, and official sales began on January 19, 1988. The model was a continuation of the Honda CBR400R Aero, having received a number of technical differences - from the aluminum frame to the engine. Currently, Aero is extremely rare on the market, and in fact it is not a CBR400RR, so it will not be considered in this review.


Main competitors:

The Honda CBR400RR was based on an in-line 4-cylinder liquid-cooled engine with a volume of 399 cc, producing up to 59 hp. power and up to 39 Nm of torque. Since 1993, Japanese legislation has been updated, forcing thereby to reduce the maximum power to 53 hp. and limit the speed to 180 km / h.

This engine, with minor modifications, was also installed on the Honda CB-1 model.

In February 1990, the Honda CBR 400 RR model undergoes a restyling (the NC23 generation is changed to NC29 , according to the frame number), receiving updates in appearance and technical part: a new cast aluminum frame (instead of tubular), new intake system, new carburetors (VP01 instead of VG04), lighter pistons, new rear swingarm, new ignition (PGM), new wheels.

In 1993, in addition to changing the engine power (reduced to 53 hp, as required by new legislation), the CBR400RR model receives a new cartridge fork with rebound damping and other rear suspension settings.

1999 was the last year of production of the model, after which it finally left the market and did not receive further development.
