The 1991 VFR400R was the NC30 in mid-life form, with the 360-degree crank V4, RC30-style bodywork and single-sided swingarm unchanged. It sold mainly in Japan, had limited official sales in Europe, including the UK, and was widely grey-imported. It was valued for its quality, its broad spread of power and its handling.
