Kawasaki Z900 (2017-2019, ZR900B/D) Maintenance Schedule and Service Intervals

This is the maintenance schedule and service intervals for the Kawasaki Z900 from 2017-2019, including the ABS versions (ABS was optional in some markets). The marketing code for this model line was the ZR900B/D.

The Kawasaki Z900 took over from the Kawasaki Z800 in most markets, but in the US it also replaced the Kawasaki Z1000 in Kawasaki’s line-up.

The Kawasaki Z900 is a naked bike based on a 948cc inline-four liquid-cooled engine that kind of is stretching the definition of “middleweight”! Yet again, Kawasaki does their own thing.

The Kawasaki Z900 is an underdog in the hot middleweight street/sport bike world, but it is a high-performing bike, making an impressive 91 kW (125 hp) @ 9,500 rpm, and 98 Nm (73 ft-lb) of torque at 7,700 rpm.

In 2017-2019, the Kawasaki Z900 was available with optional ABS in some markets. This became a standard feature in 2020.

In 2020 it got a general revamp at the same time, with a TFT display and an updated chassis, plus revised emissions control systems. Maintenance for the 2020+ Kawasaki Z900 is slightly different and so has been kept separate.

The Kawasaki Z900 also shares a platform with the retro classic Kawasaki Z900RS, although the latter has many different components and the engine has a different state of tune.

Kawasaki Z900 Service Intervals

The Kawasaki Z900 has 7600 mile / 12000 km or annual service intervals. At every service, change the oil and filter.

For emissions and safety purposes, Kawasaki also recommends you check the evap canister and brakes between services. But the next-gen Z900 removed this obligation.

The major valve service interval for the Kawasaki Z900 is every 15200 miles or 24000 km.

The Z900 has a liquid-cooled engine, so you need to refresh the coolant according to the schedule.

Also be sure to keep your brake fluid fresh, replacing it every 2 years with something DOT 4 compliant.

Kawasaki Z900 Maintenance Schedule

Maintaining Your Chain on the Kawasaki Z900

It’s important to maintain your chain on the Kawasaki Z900, as on any chain-driven motorcycle, but especially on the Z900 as it’s a sports motorcycle that you’re likely to use a little more aggressively than a more mild-tempered bike.

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 taskEvery
Check drive chain lubrication condition, lubricating if necessary (Motul chain paste)400 mi / 600 km
Check drive chain slack (free vertical movement of chain), adjusting if necessary
Standard slack: 25-35 mm (1-1.4 in)
600 mi / 1000 km
Chain maintenance — Kawasaki Z900

However, if you ride your motorcycle in dusty, muddy or rainy conditions, or regularly track / race your Kawasaki Z900, then check/adjust the chain slack and lubrication more often.

Finally, always lubricate the chain after washing the motorcycle.

About the Kawasaki Z900 (2017-2019)

The Kawasaki Z900 is one of the underdogs, a somewhat lesser-appreciated gem in the middleweight sports bike segment.

The Z900 loses the limelight to its more attractive stablemate the Z900RS, and just isn’t as hot in the market as competitors like the Triumph Street Triple RS or the Yamaha MT-09 SP.

There’s a lot to like about the Kawasaki Z900, starting with its engine. Its engine is a peach. It’s perfectly suited to the chassis. It makes just the right amount of torque to get the wheel off the ground in anything up to fourth gear without overpowering it. And the suspension is firm, but not likely to upset you, even on bumpy roads.

The Z900 is a well-loved bike by everyone who rides it. Here are a few things people say as praise

  • “Confidence-inspiring” (Schaaf, Austrian motorcycle blogger).
  • A perfect 10/10” — Bikereview.com.au (they just loved the thing)
  • “Three bikes in one” — Revzilla, Common Tread

Compared the the former Z800, the Z900 is both more powerful and much lighter. It’s also lighter than the Z1000, a bit less surprisingly.

Compared to the Z900RS, its hipster rival, the Kawasaki Z900 is also lighter and more powerful. So why do people ride the Z900RS? Well, comparing the Z900 and Z900 RS you can see that aside from design and general aesthetics, the Z900RS has a more torque-forward disposition and more advanced suspension. With a bit of a tune, the Z900RS is a compelling offering. But it’s also a lot more expensive.

The only slight against the Z900, by some people, is the aesthetic. Called “Sugomi” design, it’s Kawasaki’s branded design philosophy of creating a bike that’s aggressively postured, like a crouched animal, ready to strike. It’s not for everyone.

But if you can get behind that (or if, like me, you can’t stop looking at that combination of the green frame and glossy black paint), the Z900 is unlikely to disappoint you.
