Kawasaki ZX-6 and ZZR600 Gen 1 (1990-2004) Maintenance Schedule and Service Intervals

This is the maintenance schedule with associated service intervals for the Kawasaki ZZR600, previously (or in other markets) known as the ZX-6. This is the 1st gen ZZR600 before it was re-issued in the 2000s.

The Kawasaki ZZR600 (ZX-6) was a sports motorcycle, later re-classified as a sports-touring motorcycle. It was Kawasaki’s flagship 600cc until the ZX-6R was released in 1995.

In Europe, the model was always known as the ZZR600, but in some other markets, it was renamed from the ZX-6 to the ZZR600.

From 2005, the ZZR600 evolved slightly, taking on the engine from the earlier generation ZX-6R. See here for the maintenance schedule for the 2nd gen ZZR600 / ZX-6.

Maintaining Your Chain on the Kawasaki ZZR600 / ZX-6

It’s important to maintain your chain on the ZZR600 / ZX-6, as on any chain-driven motorcycle. Use a good-quality chain lubricant like Motul chain paste, or a Motul chain care kit which comes with a couple of handy tools to maintain the chain.

Kawasaki recommends you follow the following chain maintenance schedule:

Chain maintenance itemEvery
Check drive chain lubrication condition, lubricating if necessary (Motul chain paste)400 mi / 600 km
Check drive chain slack, adjusting if necessary600 mi / 1000 km
Chain maintenance — Kawasaki ZZR600 / ZX-6

Notes:

  • Do these items (checking/adjusting slack, and checking/applying lubrication) more often if you ride your ZZR600 / ZX-6 in dusty or rainy conditions, or if stressing your motorcycle a lot.
  • Always lubricate the chain after washing the motorcycle.

About the Kawasaki ZZR600

The original Kawasaki ZZR600 is powered by a compact 599cc liquid-cooled four-cylinder engine similar to the high-performance ZX-6R powerplant.

It’s a very modern engine, with dual overhead cams, four valves per cylinder, and a range of technologies from higher-end sportbikes to make sure the engine is both high-power and has quick throttle response.

In the heyday of the 1990s, the most popular motorcycle category was the 600cc class. They were considered the best compromise between power and handling. Bigger bikes were too heavy or cumbersome, and of course smaller bikes were too slow!

But even in the 1990s, riders recognised that not everyone could afford to be — or would want to be — on a track-focused superbike. Thus was born the category of street-friendly supersports like the Kawasaki ZZR600.

These days, you’d equate the ZZR600 to something like the Honda CBR650R — a sport bike that could do double duty in street and track riding.

While the original ZZR600 / ZX-6 is aging, it’s no slouch. The 599 cc engine pumps out 98 hp / 73 kW at 11500 rpm, a very respectable number, with peak torque coming on at 9500 rpm and at 64 Nm / 47 ft-lb. Though you’d probably need to give a little attention to the engine to make sure it was operating at its full potential.

Final drive is via a 6 speed transmission and a chain.

Brakes are pretty impressive for a so-called road bike, too, with 300 mm discs and 4-piston calipers. And the tyres are the spec you’d expect on a sport bike — 17 inch front and rear, though with an older-fashioned 160/60 profile at the rear.
