When it came time to scrub off speed, the single, 11.8-inch front disc was generally up to the task-two fingers on the adjustable lever were all it usually took. The Custom's performance is about what I'd expect from a bike in this class: strong, competent and willing, but no Barbaro, either.A full array of gauges-tripmeter, odometer and clock-are accessible via an LCD display set in a tank-top console. It's all very trick, so the question becomes why did Kawasaki drop the ball with rear-end styling? The Custom is a looker forward of the engine, but that 15-inch rear hoop is puny. There's no hiding the noticeable gap between the fender and tire.
