No kidding, didn't know that.The CB450 was unique with the torsion bar to close the valves, instead of springs.
I liked the four cylinder Honda 350's and 400's.
The 400 was way cool with its four into one pipe going up and out one side.
A friend of mine had a red one. He sold it not long ago.
I had Kawasakis back in the 70's...
