| 1978 | Year development began on the NR500 Grand Prix bike, Honda's first V4. |
| 93.4 x 41mm | Dimensions of the NR's four oval pistons. The shape afforded the increased piston speed and valve area of a short-stroke V8 without violating the FIM's four-cylinder maximum. |
| 8 | Tiny valves for each oval piston. Intake valves measured 18mm and exhaust valves measured 16mm, both on 3.8mm stems. Each piston had two connecting rods. |
| 20,000 | Spare parts that Honda shipped to the 1979 British Grand Prix, where the NR debuted. |
| 38th | Takazumi Katayama's qualifying position at the British GP. Teammate Mick Grant qualified 41st. |
| 200+ | Patents granted to Honda related to the NR500, for technology as diverse as oval pistons, side-mounted radiators, an inverted fork and Pro Link rear suspension-innovations that still influence Honda streetbikes today. |
| 1982 | Year the VF750S Sabre and VF750C V45 Magna, Honda's first production V4s, were released. The V45 Interceptor appeared in 1983. |
| 21 | Years the Magna cruiser stayed in production, before being discontinued in 2003. The standard-style Sabre disappeared after 1985, though the name reappeared on a V-twin muscle cruiser this year. |
| 10.92 | Quarter-mile E.T of the 1983 Honda V65 Magna, the first production streetbike under 11 seconds. |
| 7 | V4-powered offerings in the 1984 American Honda line-up-the peak of V4 popularity in this country. |
| 1990 | First year for the ST1100 sport-tourer, which mounted its 1084cc V4 longitudinally instead of transversely like Honda's other V4s. |
| 8 | Number of years the Interceptor name was dropped, beginning in 1990, to make the VFR sound more innocuous to American insurance companies. The name returned in 1998. |
| $50,000 | Price tag of the 1992 NR750, Honda's only oval-piston streetbike. The company produced just 200 of these exotic, hand-built machines. |
| 186.319 | Speed, in mph, achieved by Loris Capirossi in August of '92, riding a de-restricted, 155-bhp NR750 at Fiat's test track in Nardo, Italy. This established a new flying-mile world speed record for 750cc motorcycles. |
