Now there are plenty of bikes that can go 170, but in 1990 there was only one, and the aerodynamic, ram-air fed 1052cc ZX-11 was it. Kawasaki called on its bullet-train building experience in designing the thing. It was over-the-top ridiculous, but it was (and probably still is) a great sport-tourer. All of us had a hard time keeping our drivers licenses in those days; thank God we’ve matured.
