What was the name of Kawasaki's first production motorcycle?

The bike gurus should know this. Help me out guys.|||That's Tricky Bruce,





The First actual Kaw was a '62 B8 125cc





Same bike was made in '61,,,called a B7.





But it wasnt a actual Kawasaki yet,,it was a subsidiary company Kaw owned./bought after making engines for them for several years
