Honda has produced several cars that feature engines derived from their motorcycles. One notable example is the Honda S600, which was manufactured from 1964 to 1966. The S600 was a small sports car equipped with a 600cc four-cylinder engine that was derived from Honda's motorcycle engine technology. This engine featured dual overhead camshafts and was capable of high revs, similar to Honda's motorcycle engines of the time.
Another example is the Honda Beat, a kei car produced from 1991 to 1996. The Beat featured a 656cc three-cylinder engine, again derived from Honda's motorcycle engine technology. This engine utilized fuel injection and had a redline of 9,000 RPM, reflecting its motorcycle heritage.
These are just a couple of examples, but Honda has a history of utilizing their motorcycle engine technology in their cars, particularly in smaller, lightweight models.
