The VF and VFR series motorcycle was a V-type four cylinder engine design from Honda resulting in a street bike. MotorCycle is the title of a 1993 album by Rock band Daniel Amos, released on BAI Records. A V engine is a common configuration for an Internal combustion engine. An engine is a mechanical device that produces some form of output from a given input () is a Multinational corporation, engine Manufacturer and engineering corporation headquartered in Japan. MotorCycle is the title of a 1993 album by Rock band Daniel Amos, released on BAI Records. The bike was also first to utilize a Sprague (one way) clutch.
The V-Four engine was very prominent in Honda's early 1980s model line-up, with engine capacities ranging from 400cc to 1000cc. Year 1980 ( MCMLXXX) was a Leap year starting on Tuesday (link displays the 1980 Gregorian calendar) The V-Four design had only been used a few times in the history of motorcycles, most notably by Matchless. Matchless is one of the oldest Marques of British Motorcycles with the first models manufactured at the start of the 20th century The concept probably came about as a loose derivation from the NR500 oval pistoned V-Four racer. NR500 was an innovative racing Motorcycle developed by Honda HRC in 1978 to compete in Grand Prix motorcycle racing. The earliest VF series engine was designated the V45 for its size (45 in³ or 748 cc), was very narrow being only 16 inches (406 mm) wide, and had perfect primary balance making for a smooth, nearly vibration-free engine. A smaller V30 (500 cc) engine and a larger V65 (1100 cc) engine were also available, the latter becoming known as the fastest production bike in its time, and the original competition for the famous Yamaha VMax. The Yamaha V-Max is a Motorcycle manufactured by Yamaha, which is known for its powerful V4 engine, shaft drive and distinctive styling
In 1982, first year of the VF models, reliability and quality control problems abounded due to new automated production equipment at Honda's plant in Hamamatsu, Japan [1]. Year 1982 ( MCMLXXXII) was a Common year starting on Friday (link displays the 1982 Gregorian calendar) is a city located in western Shizuoka Prefecture, Japan, and is the largest city in the prefecture For a topic outline on this subject see List of basic Japan topics. Regardless, Honda sold out its first year inventory of Sabres, and the Magnas were not far behind. 1983 was a new year and a new start for the VF series of bikes, seeing the engine revised to correct the problems from the previous model year, and saw the introduction of the V65 and the Interceptor. Year 1983 ( MCMLXXXIII) was a Common year starting on Saturday (link displays the 1983 Gregorian calendar) 1984 was the year the infamous cam-wear problem surfaced in the larger displacement bikes, which, by the time it was corrected, led to eight factory cam revisions over the course of just one year. Year 1984 ( MCMLXXXIV) was a Leap year starting on Sunday (link displays the 1984 Gregorian calendar) The cam chain-driven valvetrain was later dropped from the VFR in favor of gear driven cams, to help distance the VFR from the reputation of earlier VF engines for faulty cam-chain tensioners that would allow for the tensioner to reach maximum travel, but the chain would still be within service limits . As the tensioner problem faded into Honda V4 history with recent redesigns, 2002 and later VFR engine designs have reverted to chain-driven cams.
The RC30 was the racing version, replaced later by the RC45. The Honda VFR750R, frame designation ' RC30', was a fully faired racing motorcycle created for homologation purposes for the World Superbike championship by Honda Racing Corporation The Honda RVF750R RC45 was a fully faired racing motorcycle created for Homologation purposes for the Superbike World Championship by Honda Racing Corporation In 1998 the VFR750 was replaced by the re-designed VFR800Fi, with a displacement of 788cc and fuel injection. Year 1998 ( MCMXCVIII) was a Common year starting on Thursday (link will display full 1998 Gregorian calendar) The Honda VFR750F is a sport touring Motorcycle produced between 1986 and 1997. The Honda VFR800/Interceptor is a Motorcycle introduced by the Honda Motor Company in 1998 Fuel injection is a system for mixing fuel with air in an Internal combustion engine. In 2002 Honda released the VTEC version, which dropped the gear driven cams. See also 2002 (disambiguation Year 2002 ( MMII) was a Common year starting on Tuesday of the Gregorian calendar. VTEC is also an abbreviation for the Verocytotoxin -producing Escherichia coli strain O157H7. The VTEC is different from the technology used in Honda cars, where the valve timing varies. On the 6th generation VFR, below 6,800 rpm, two valves per cylinder open and close, resulting in greater fuel economy and lower emissions. Critics, however, say this robs the engine of some of its power. Above the 6,800 rpm, the VTEC valves open and four valves per cylinder operate. Some critics say that the transition from one mode to another is not smooth, creating a jolt which can be unsettling if it happens mid-corner.
