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 race models of the day.〔Performance Bikes, March 1990, p. 8:"The scaled-down, 400cc version of the RC30 is perfect in its proportions and in its detail. The reduction in size makes it neater still."〕 They were mainly developed for, and sold in, the Japanese domestic market, in part due to the tougher motorcycle drivers' license restrictions in Japan at the time for bike exceeding 400cc. Outside of Japan, the VFR400R (NC30) was officially imported to the United Kingdom for four years, but with a price tag of £5899〔Performance Bikes, March 1990, p. 8:"Of course, being well-informed, you already know about the £5899 price..."〕 (similar to that of the 1000 cc 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 so for the NC30 in the United Kingdom,〔Performance Bikes, September 2001, p. 82:"More of them have been imported - a few officially by Honda UK, but mostly by other means - than any other 400 race-rep."〕 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 straight cut gears, rather than chains or belts. ==Model history== The first generation of VFR400R was the 1986–1987 NC21, which had replaced the VF400F when the Honda VF series was phased out (mainly due to reliability issues with the head and cam chain). This model had a full fairing, single headlight, a conventional dual-sided swing arm with single shock. The clutch was hydraulically actuated and the front forks featured Hondas TRAC (Torque Reactive Anti-dive Circuit) system. The engine was a 180° degree crank firing version, and had a rpm redline of 13000 rpm. It was offered in three colour schemes. The NC21 was also available as the VFR400Z, a semi-faired version, and as the VFR400P, a police-specification version. A small number of NC21s (VFR400R) were imported new into New Zealand in 1987. The 2nd 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). Discontinued with this model were the hydraulically actuated clutch which was switched back to a cable system, and the TRAC anti dive system on the front forks. Styling remained close to the NC21, with the NC24 keeping the single large headlight and the exhaust silencer on the right hand side. This model also had a 180° deg crank firing engine as with the nc21, but redline was raised to 14000 rpm. The NC24 was available in three colour schemes in 1987 (including an official Rothmans replica), and one in 1988. Note that the rear wheel on the NC24 was held onto the hub with 4 bolts. The third generation of VFR400R was the best known version, the VFR400R NC30. This saw styling changes, most notably the headlights were updated to smaller twin headlights, much the same as the RC30, and relocation of the silencer to the left hand side, which gave a more open look to the rear wheel on the right hand side. This model saw the introduction of the 360° crank firing engine, which is also known as the "big bang" engine. The tachometer red-line was also raised to 14500 rpm. The NC30 was also officially sold in limited numbers in several European countries. The official European models were sometimes installed with a different CDI (ignition device), no restriction, speedometer that reached to and larger headlights (Germany). 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 official UK model has the following distinguishable features: slightly larger front and rear direction indicators; additional rear number plate light (separate from rear lamp) oil cooler, 60/55 watt headlamp bulbs, and a MPH speedo. The official UK bikes were only ever available in two colour schemes. The Honda VFR400R NC30 is widely regarded as being a fine handling motorcycle. 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 and racing bike. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Honda VFR400」の詳細全文を読む スポンサード リンク
