This is the maintenance schedule with associated service intervals for the Kawasaki Z800, made from 2013-2016, before being replaced by the Z900 in 2017.
The Kawasaki Z800 is one of Kawasaki’s iconic “Zed” range (or “Zee”, I admit), an upright standard bike powered by an inline four-cylinder engine. The motor in the Z800 is an 806cc 4-stroke liquid-cooled inline 4-clinder engine that makes 83 kW (113 hp) @ 10,200 rpm and 83 Nm (60 ft-lb) @ 8,000 rpm. So a quite sporty motor that revs quite high.
The Z800 was a big improvement on the Kawasaki Z750 that it replaced, which was considered too heavy for the power it made. It’s a “less frantic” alternative to the Street Triple or the MT-09 of the time. By today’s standards it’s a tad heavy, weighing in at 229kg wet, but it’s still possible to have a lot of fun on one.

What you need to service your Kawasaki Z800
If you’re servicing your Kawasaki Z800, you need some basic motorcycle maintenance tools, as well as the following consumables.
|Part||Kawasaki Z800 Spec|
|Oil||You need SAE 10W-40 engine oil with API SH or SJ (or newer, e.g., SL or SM) with JASO MA rating, for example, Kawasaki 10W-40 Engine Oil, or another high-grade oil like Motul 7100.|
Don’t over-torque the drain bolt (spec is 30 Nm/22 lb-ft per the manual) — use a torque wrench if you don’t have experience with how much torque is enough.
|Oil filter||Use a Hiflofiltro filter for easy replacement, part HF303RC. Torque for oil filter is 18 Nm (13 ft-lb).|
|Chain||Maintain the chain with Motul chain paste, a popular chain lubricant.|
|Brake pads||Many riders upgrade to EBC HH brake pads.|
|Spark plugs||NGK CR9EK, torqued to 13 Nm or 9 ft-lb (use a torque wrench).|
|Air filter||Most people replace the OEM air filter with a K&N aftermarket air filter (functionally identical), part number KA-1003.|
|Brake/Clutch fluid||Spec is to use DOT 4 brake/clutch fluid, e.g. Castrol DOT 4.|
|Coolant||Use, as ships with the Z750, 50/50 pre-mix of ethylene glycol-based coolant with anti-corrosion inhibitors, e.g. Valvoline Zerex G05|
|Grease||Use a lithium soap based grease for all the important greasing points.|
Maintenance Schedule for Kawasaki Z800
Below is the maintenance schedule for the Kawasaki Z800.
Maintaining your Z800 is much like maintaining any four-cylinder standard bike. You have a chain, you have an inline-four transversely-mounted engine, and you have relatively few body panels.
The core of maintaining the Z800 is to make sure you:
- Regularly lubricate and clean the chain (use a Motul chain care kit)
- Change the oil and oil filter every year or prescribed interval, and
- Change the core fluids (brake fluid, coolant) every 2-4 years.
The following is the list of maintenance items that you should do to maintain the Z800. Do whichever one arrives earlier.
- For higher odometer readings, repeat at the frequency interval below.
- Kawasaki recommends a professional mechanic service the items marked with a “K” in the leftmost column (but do it yourself!)
- # (air filter, chain etc.): Service more frequently when operating in severe conditions: dusty, wet, muddy, high speed, or frequent starting/stopping.
|Items||Every years/distance||1000 km (600 mi)||6000 km (3800 mi)||12000 km (7600 mi)||18000 km (11400 mi)||24000 km (15200 mi)|

Tyre size and tyre pressure for the Kawasaki Z800
The Kawasaki Z800 has the following tyres and tyre sizes standard.
The Z800 ships with Dunlop Sportmax tubeless tyres. But you can use whatever tyres you think are appropriate (typically a modern sport-touring tyre).
|Wheel||Tyre size||Tyre pressure|
|Front||120/70 ZR17 M/C (58W)||250 kPa/36 psi|
|Rear||180/55 ZR17 M/C (73W)||290 kPa/42 psi|
General information about the Kawasaki Z800
The Kawasaki Z800 was a welcome replacement for the Z750 that it replaced. It was sold alongside the 4th gen Z1000, both of them sharing a lot of similar “Sugomi” design cues.
The Z800 was the latest in the long line of middleweight Z-bikes from Kawasaki, a line that stretches back to the 70s — though it has gone through many changes since then.
The Kawasaki Z800 has a liquid-cooled inline four-cylinder 803cc engine that makes 83 kW (111 hp) at the crank, enough to get you into serious trouble.
The suspension on the Z800 is surprisingly competent. It has 41mm inverted KYB forks on the front, adjustable for preload and rebound damping. The rear piggyback shock is also adjustable for preload and rebound damping. The suspension even in stock form it’s “pretty good”, in contrast with the MT-09 of the time (which was “pretty soft”). They lack rebound damping adjustment, but this is a middleweight, after all.
The engine is a bored out version of the Z750’s engine. To help it improve in power, Kawasaki revised the intake and exhaust, increased the size of the throttle bodies, and gave the internals a work-over — a plating finish, and lighter weight pistons (10% lighter than on the 750). All this gave the Z800 an additional 4 kW (6 hp), with more torque all through the rev range.
Kawasaki also added two teeth to the rear sprocket, helping the Z800 a lot with low-end acceleration.
The chassis is a revised version of the one on the Z750, though with a longer swingarm, and a new subframe.
Kawasaki did improve the brakes over the Z750, increasing the disc size by 10mm to 310mm. ABS was optional in some markets, and standard in others.
Now that the Z900 has been released, it’s hard to drool over the Z800 in the same way — the Z900 is more powerful, lighter, and still feels balanced. But the Z800 is still a great bike, capable at commuting, destroying canyons and everything in between. It just takes a bit more effort to steer. But rev it up and you’ll be rewarded with Kawasaki’s signature intake roar!
There were no updates to the Z800 during its time. There was a “Performance Edition” released (with an Akrapovic exhaust), and a similar Sugomi edition (also with an Akrapovic exhaust, and some other graphics etc.), but nothing fundamental changed inside it.
