This is the maintenance schedule with associated service intervals for the Kawasaki Z750 and Z750S, made between 2004 and 2012.
The Kawasaki Z750 was the smaller of Kawasaki’s stable of naked motorcycles — the smaller sibling to the Z1000 of the time.
The Z750, and the later-released Z750S (same bike but with a small cowl fairing), is powered by a liquid-cooled, 748cc, in-line four-cylinder fuel-injected engine that delivers a smooth linear powerband.
The Kawasaki Z750 was actually the first middleweight to be fuel-injected. That, and its ahead-of-its-time design, makes it a well-favoured used bike. Also the fact that it made a healthy 78 kW (106 hp), putting it on par with most middleweight 600cc-class sportsbikes… but with a much flatter torque curve, and in a chassis that many would now call a “streetfighter” (i.e. naked, but slightly sportier and more forward-leaning).
Kawasaki replaced the Z750 with the Z800 in late 2012 (for the 2013 model year).

What you need to service your Kawasaki Z750 (or Z750S)
If you’re servicing your Kawasaki Z750 or Z750S, you need some basic motorcycle maintenance tools, as well as the following consumables.
|Part||Kawasaki Z750/S 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. Some owners (e.g. this thread) like Shell Rotella T6.|
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 Z750
Below is the maintenance schedule for the Kawasaki Z750 and Z750S.
Maintaining your Z750 is much like maintaining any four-cylinder standard bike. You have a chain, you have an inline-four engine, and you have few body panels. Make sure you
- Regularly lubricate and clean the chain
- Change the oil and oil filter every year or interval, and
- Change the core fluids (brake fluid, coolant) every four years.
The following is the list of maintenance items to be done on this motorcycle with a time or distance interval — whichever comes earlier.
The maintenance for the Kawasaki Z750S is broken into three sections: Engine Related Items, Chassis Related Items, and Change/Replacement Items.
- For higher odometer readings, repeat at the frequency interval established here.
- Kawasaki recommends a professional mechanic service the items marked with a “K” in the leftmost column.
- #: Service more frequently when operating in severe conditions: dusty, wet, muddy,
high speed, or frequent starting/stopping.

Tyre size and tyre pressure for the Kawasaki Z750/S
The Kawasaki Z750/S has the following tyres and tyre sizes standard.
The Z750 ships with Bridgestone BT012 tubeless tyres. But you can use whatever tyres you think are appropriate (typically a modern sport-touring tyre).
|Wheel||Tyre size||Tyre pressure|

|Rear||180/55 ZR17 M/C (73W)||290 kPa/42 psi|
General information about the Kawasaki Z750
The Kawasaki Z750 is a smaller Z1000. And the Z750S is a Z750 with a small fairing.
You could look at it as less bike… but many look at it as a more appropriate amount of bike. The lower power and higher gearing mean you get to shift more, which to some (me) is the joy of motorcycling. Not for everyone, sure!
The Z750 (from 2004) and Z750S (from 2005) are powered by a liquid-cooled, 748cc, in-line four-cylinder engine with fuel injection from the outset. Both bikes competed with the Honda Hornet 600, though considering they were similarly priced, the Z750 was a favourite.
The engines have a bore of 68.4mm and stroke of 50.9mm, double overhead cams with 16 valves, and a four-into-one exhaust system.
Kawasaki updated the Z750 in 2007, retuning the engine for less vibration and more low-end torque, and changing the front suspension to a USD fork and the front and rear disc brakes to petal rotors.
There was also the Z750R launched in 2011, which had upgraded suspension and brakes, and slightly updated styling.
Manual for the Kawasaki Z750/S
The above maintenance schedule comes directly from the user’s manual for the 2006 Kawasaki Z750S, which is available here. It has the same schedule as in other years of the Kawasaki Z750.
