The NS250R was Honda's first real road-going replica of its 250 cc Grand Prix bikes, with a liquid-cooled 90-degree V-twin two-stroke, RC power valves in the exhausts and an aluminium frame. It was a sharp, light handler on fast bends and circuits, but its narrow, peaky power band and two-stroke smoke made it hard work in traffic. It was replaced by the all-new NSR250R.
