Awesome read! Thanks OldF7Guy!
I remember reading this article when it came out, over and over. I was a teenager then, and was riding my trusty Yamaha 175, but I was about to move up, and was struggling to decide, and save money, for a big bike.
"The Mach IV is the quickest, most intense; most single-purpose street machine ever built for general consumption, a streaming, purple-eyed monster that does everything with a shriek and whose only God is performance. Lay at its feet the hottest production vehicle you can name—two wheeled or four—and the Mach IV will chuckle, snort, and eat it alive. Its limitations are exactly as you would suspect: the engine makes a lot of racket, it doesn’t have much of a reputation for gas economy, and you have to know what you are doing to live with it in comfort." Cycle World Magazine, 1973
My best friend was riding a Kawi H2-750 at this time, I rode that bike regularly, and it was everything the magazine said. That bike foamed at the mouth, and was like a rabid bull, but soooo much fun! You absolutely had to know how to handle it, or it would dump you, it wheelied without so much as a thought, up to and including third gear.
My above mentioned friend moved on to a '73 model Z1, and I bought the H-2. So I have fond memories of both of these bikes.
Eventually, my friend's Z-1 got an American TurboPak turbocharging kit, a fiberglass mono body, (remember those?), and with a slick and wheelie bar recorded a 9.8 second et with a terminal speed of 148mph at Hallsville drag strip in East Texas. That was smoking in 1976.
My trusty H2 sported ported and polished heads by Denco, as well as Denco expansion chambers, big Mikuni carbs, velocity stacks, a slick and wheelie bar and turned in 11.3 et @119mph.
Ahh, those were the days.
I think that one reason I appreciate my CB1100 is because it dovetails nicely with those Kawi Z-1s in most every way, and is more refined. But they truly do a lot of things very well, and the performance is a little better. In 1973 our CB's would have been king of the hill!
