EDITOR TERLICK SAYS: Right at the end of the 1960s, Kawasaki and Honda were both secretly working on all-new top-of-the-range bikes to show the world they could build big bikes better than anyone else. Both were in-line four cylinders, and both were 750cc. Honda was first to hit the market, its CB750 Four proving such a success it took everyone — including Honda — by surprise. Kawasaki retreated to the design table to take the big-bike market another leap forward. When it finally released the Z1 in 1972, it had grown to 903cc with a double-overhead cam engine that was good for 82 horsepower and 132mph. The Z1 whacked the CB750 out of the park and became the must-have Japanese bike of a generation. Very early Z1s are now fetching seriously big money (one recently sold at auction in the USA for $US50,000) and all the 1970s Zeds have now become collectibles. This bike of Peter’s looks to be a great useable classic, its customisation adding some later-model reliability and functionality, while retaining that unmistakeable Z style.
