About the 1998-2002 Kawasaki Ninja ZX-6R

2001 Kawasaki ZX-6R

The 1998-2002 Kawasaki ZX-6R is an early Kawasaki sport bike, still in production today in its latest iteration as the 2013+ Kawasaki ZX-6R 636.

In the mid 1990s, the first-gen 1995 Kawasaki ZX-6R is credited with causing other manufacturers to re-think their approach to sport bikes, though the first Kawasaki ZX-6R was in itself a response to the success Honda was having with the early carburettor-fed CBR600F.

The 1998 model of the ZX-6R was a significant revamp of the first 1995 model ZX-6R. Kawasaki made the bike smaller, more focused, and more race-oriented… and even cheaper.

Kawasaki overhauled the

  • Engine — making it lighter and quieter, though the quoted power spec is the same (as is the bore and stroke)
  • Chassis — making it lighter
  • Suspension — upping the spec to something they considered more racetrack-ready, with a 46 mm conventional fork (replacing the 41mm fork)
  • Brakes — giving the 1998 bike 6-piston calipers, replacing the 4-piston units

The end result is a more refined bike, both smoother and easier to ride quickly.

In 2000, Kawasaki made some updates to this model, upping the compression ratio, redline, and peak power output, also giving the 2000 models coil-over plugs to help keep up.

Kawasaki also changed the tire profiles for the 2000 models, so check the specs above to make sure you have the right ones!
