Currently available at a Yamaha dealership way down in Memphis, Tennessee, this muscular '07 Kawasaki Z1000 is pretty clean. A vision in black, it seems to have an aftermarket exhaust and maybe an aftermarket rear wheel (sure looks like it), but there's precious little information available on this bike from the dealership's website. It currently has about 16,000 miles on the clock, which is just about broke in for the big 953CC inline four that powers this beast. If you do grab this one, make sure you head on over to Graceland and tell The King we said hello.
