A friend of mine sent me this little tidbit and I had to share it with you but first some background. Way back in high school I was the owner of a red Honda 600 Sedan. It was a fantastic car, fun and quick but not very fast. It had a 600cc vertical twin motor much like a bored over CB350. It was so light that my class mates would pick it up a put it in impossible places.
This 1972 Honda N600 is highly modified. It is powered by a liquid cooled V4 from a 1998 Honda VFR800 Interceptor. The car is setup for fast road and autocross use, and the owner spent several years dialing in the build. It features four wheel independent suspension based on shortened Miata components, paddle shifters for the sequential transmission and a 12k RPM redline. This is a quick N600 that is said to be capable of 127MPH and very nimble.
Nimble is the word. At higher speeds, the steering is so quick that I would have to hold the steering wheel steady with my knees to stay in my lane. My little 600 would run a honest 80mph and that was truly frightening. A speed of over 100 would be terrifying. Sounds like fun!
