With its ZRX retro-sport looking a touch, well, retro these days, Kawasaki introduces the Z1000--a naked bike with the heart of a ZX-9R and a steel-tube skeleton with plenty of appropriately belligerent avant-garde style. Actually more scantily clad than buck naked, Kawasaki's counter to the Yamaha FZ1 slots in as a feisty, up-to-date alternative to the ZRX1200--which returns for 2003--for literbike fans who think the fetal racer-replica tuck is a pain. Seating arrangements are comfortably sporty; there's plentiful legroom and a humane reach to the gold-anodized aluminum handlebar. As on Kawasaki's '03 600s, instrumentation lives in a nicely turned out circular pod, wrapping a segmented LCD tachometer around the digital speedometer. In recognition of those who like showing up on time, there's also a digital clock. That swath of aluminum angling down from beneath the fuel tank is a bolt-on facade. Underneath, the Z1000 frame is comprised of thin-wall steel tubes arrayed in what Kawasaki calls a diamond configuration, welded to a pressed-steel section rising vertically from the swingarm pivot. The swingarm itself is extruded aluminum, lifted directly from the '01 ZX-9R.
