These were the days for 600cc supersports: "Hot Damn!" the cover declared on the arrival of Kawasaki's all-new ZX-6. The little Ninja used its 36mm Keihin carbs to make 100 horses, spin to a then-astronomical 14,000-rpm redline, and run a super-solid 11.36-second quarter-mile, all while being a great streetbike. "The result is, without doubt, the most powerful, best performing production 600 ever made," we declared. MSRP was $5,499 and no-fuel weight on the CW scale was a beefy 461 pounds.
