Honda NS500
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.

Four-stroke
A four-stroke (also four-cycle) engine is an internal combustion (IC) engine in which the piston completes four separate strokes while turning the crankshaft. A stroke refers to the full travel of the piston along the cylinder, in either direction. The four separate strokes are termed: #Intake: Also known as induction or suction. This stroke of the piston begins at top dead center (T.D.C.) and ends at bottom dead center (B.D.C.). In this stroke the intake valve must be in the open position while the piston pulls an air-fuel mixture into the cylinder by producing vacuum pressure into the cylinder through its downward motion. The piston is moving down as air is being sucked in by the downward motion against the piston. #Compression: This stroke begins at B.D.C, or just at the end of the suction stroke, and ends at T.D.C. In this stroke the piston compresses the air-fuel mixture in preparation for ignition during the power stroke (below). Both the intake and exhaust valves are clo ...

NR500
NR500 was a racing motorcycle developed by Honda HRC in 1979 to compete in Grand Prix motorcycle racing. "NR" stands for "New Racing". Model history The motivation behind the NR500 was company founder Soichiro Honda's desire to compete using four-stroke engine technology since the majority of motorcycles manufactured by Honda used four-stroke engines. When the FIM announced new regulations for the 1968 Grand Prix motorcycle racing season that limited the 500 cc engines to four cylinders, this gave an advantage to teams using two-stroke machinery. Honda decided to withdraw from motorcycle racing to concentrate on its automobile division. In November 1977 Honda announced it would be returning to motorcycle Grand Prix racing using four-stroke technology. Even though two-stroke engines dominated motorcycle Grand Prix racing in the late 1970s, Honda felt compelled to race what they sold and thus competed using a high-technology, four-stroke race bike.
