Kawasaki detuned the all new engine from 65 hp to 62 hp to maximize fuel economy. Our presence is being noted. I can ride the bike through town at 35 mph in top gear at 2,800 rpm and show 85 mpgUS on the instantaneous read out. On the highway it pulses from 63 to 68 mph at 50 mpgUS and glides at something over 240 mpgUS.

"In the engine bay, some more changes to the 649cc parallel twin have come to light since we rode the Z650. Besides the smaller 36mm (from 38mm) throttle bodies, narrower intake ports, less radical cams, different airbox, and slipper/assist clutch that we noted with the Z650, a lot more has been changed internally (and externally). For example, the cylinder assembly is now an open-deck design that utilizes plated/liner-less bores for less weight and a narrower cylinder pitch (width between cylinders). New fine-atomizing injectors provide a better fuel-air mixture at the lower rpm the new engine is designed for, while the exhaust header pipes have been shortened and the crossover pipe removed to improve midrange power."
