The Honda VFR400 series of motorcycles were a related series of 399 cc V4-engined motorcycles, which were essentially scaled-down versions of the larger VFR models of the day. They were mainly developed for, and sold in, the Japanese domestic market, in part due to the restrictive motorcycle drivers' license restrictions in Japan at the time.
Outside of Japan, the VFR400R (NC30) was officially imported to the United Kingdom for four years, but with a price tag of £5899 (similar to that of the 1000cc bikes of the time and actually more than Honda's own VFR750F), failed to sell well. This model was also officially imported (in very limited numbers) and sold in Austria, France and Germany for a few years.
Although mainly produced for the Japanese domestic market, VFR400s have been popular as grey imports in other markets (especially the United Kingdom, and also for racing purposes in the United States) in the "mini" superbike segment.
VFR400 engines produce a noticeable whine when the engine is running, due to the cams being driven by gears, rather than chains or belts.
The next generation of VFR400R was the VFR400R NC24, produced for the 1987 and 1988 model years, the first production Honda motorcycle to utilize an ELF-designed Pro-Arm single-sided swingarm (which later became one of the trademarks of the Honda VFR series). The NC24 was available in three colour schemes in 1987 (including an official Rothmans replica), and one in 1988.
The third generation of VFR400R was the best known, the VFR400R NC30, which was also officially sold in limited numbers in several European countries. The official European models were sometimes companied by a different CDI (ignition device), no 180 km/h restriction, speedometer that reached to 240 km/h, larger headlights (Germany) and larger carburettors to produce 5-6 hp more. The NC30 was produced between 1989 and 1992, though unsold bikes were still available to purchase from Honda dealers for several years thereafter. The NC30 reflected the styling of its iconic bigger brother, the VFR750R (RC30), right down to its 18-inch rear wheel. Japanese-spec NC30s were available in a total of eight different colour schemes, produced with three different model year specifications (1989, 1990 and 1992). Export models were made in two different colour schemes, and carried model year designations L and M (1990 and 1991).
The Honda VFR400R NC30 is widely known to be one of the best handling roadbikes ever made. The engine has a very wide powerband for a 400cc engine, which made it a perfect beginners-superbike. It has a hardcore fanbase, especially in Japan and the UK, where the NC30 is a popular track-day bike.
