The V3 engine is a V engine with two cylinders in one bank and one cylinder in the other bank. It is a rare configuration, which has been mostly used in two-stroke engines for motorcycles competing in Grand Prix motorcycle racing.
The first example was the 1955 DKW 350. [1] The 1968 Suzuki RP68 was intended to compete in the 1968 season, however a rule change mandating single-cylinder engines meant that the 50 cc (3.1 cu in) RP68 never raced. [2] [3]
Honda later revived the layout for the 1982–1984 Honda NS500/NSR500 Grand Prix racing motorcycles. [4] The 1983–1984 Honda MVX250F and 1985-1987 Honda NS400R sports bikes also used V3 engines.
A related layout was the W3 engine, although this placed all three cylinders in the same plane, but none of them in the same bank. This was used for the 1905–1915 four-stroke Anzani engine, which was used in motorcycle and aircraft applications.
Grand Prix motorcycle racing is the premier class of motorcycle road racing events held on road circuits sanctioned by the Fédération Internationale de Motocyclisme (FIM). Independent motorcycle racing events have been held since the start of the twentieth century and large national events were often given the title Grand Prix. The foundation of the Fédération Internationale de Motocyclisme as the international governing body for motorcycle sport in 1949 provided the opportunity to coordinate rules and regulations in order that selected events could count towards official World Championships. It is the oldest established motorsport world championship.

The Honda NR was a V-four motorcycle series started by Honda in 1979 with the 500cc NR500 Grand Prix racer that used oval pistons. This was followed during the 1980s by a 750cc endurance racer version known as the NR750. The oval piston concept allowed for eight valves per cylinder which generated more power due to the increased air/fuel mixture and throughout compression. In 1992 Honda produced around 300 street versions of a 750cc model, the NR, with a 90-degree V angle. Whereas the NR500 had used an oval piston with straight sides, the road going NR750 used an elliptical piston with curved long sides. The bike became the most expensive production bike at the time when it was selling for $50,000 and with the rarity, nowadays they rarely change hands.
The Honda NSR500 is a road racing motorcycle created by HRC and debuted in 1984 for the Grand Prix motorcycle racing's 500 cc class. Honda won ten 500cc World Championships with the NSR500 from 1984 to 2002, with six in a row from 1994 to 1999. With more than 100 wins to its credit, the NSR500 is the most dominant force in modern Grand Prix motorcycle racing. The 1989 NSR500 that won Honda's third 500 World Championship with Eddie Lawson exemplifies the overwhelming power, acceleration and raw speed that has always been synonymous with Honda's 500 cc two-stroke V4.
The Honda NS500 is a 500cc Grand Prix racing motorcycle of the early 1980s, powered by a two-stroke V3 engine. Created as a replacement for the innovative but unsuccessful four-stroke NR500, the bike went against Honda's preference for four-stroke machines but proved very effective and quickly won the 1983 500cc World Championship with Freddie Spencer on board. Spencer was able to use the lower weight and superior handling of the NS500 to achieve higher cornering speeds, and getting on the power earlier leaving corners. Ron Haslam also won the 1983 Macau Grand Prix. After a relatively short lifespan the bike was replaced by the more successful two-stroke, V4 engine powered NSR500.
The 1982 Grand Prix motorcycle racing season was the 34th F.I.M. Road Racing World Championship season.
NR500 was a racing motorcycle developed by Honda HRC in 1979 to compete in Grand Prix motorcycle racing. "NR" stands for "New Racing".

The motorcycle was introduced in 1966 to compete against the ever competitive Honda racing machines and was a bored out version of MV Agusta's highly successful 350 cc three cylinder. Giacomo Agostini won consecutive world championships in the 500 cc class with this motorbike from 1966 to 1972. In addition, MV Agusta won the Constructors' World Championships from 1967 to 1972. The MV Agusta Tre is considered the most successful racing motorcycle in history.

Grand Prix motorcycle racing sponsorship liveries have been used since the late 1960s, replacing the previously used national colours. With sponsors becoming more important with the rising costs in the motorcycle CC classes, many teams wanted to be able to display the logos of their sponsors as clearly as possible.
