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 Z800 in most markets, but in the US it also replaced the 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 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.

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 much 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 motor. 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.
