I bought a magazine off of Ebay. It's title is "Road Test's Quarterly Honda Sport Cycle," Spring 1969. I paid $6.50 plus shipping! It only cost fifty cents when it was new. But, it's cheap at twice the price. It covers three of the motorcycles I had when I was a teenager. Namely, the Honda '66 (?) CL160,'69 CL-350, and the '69 CB750. These were state of the art and newest technology back then! The CB750 is recgonized as the bike that started the superbike era. Check it out. Try not to laugh at what writers said about awesome power (80 bhp and 100 mph top speeds)!
