According to the Kawasaki Z900 / Z900 SE (ZR900F) Official Owner’s Manual Maintenance Specifications, the 2017–Present Kawasaki Z900 / Z900 SE (ZR900F) (chassis ZR900B/ZR900F/ZR900P) requires 3.3 L (3.49 US qt) of SAE 10W-40 (JASO MA2, API SG/SH/SJ/SL/SM) engine oil for a drain-only change and 3.8 L (4.02 US qt) with filter service (16097-0008 / HF303). Standard solo cold tire pressure is 250 kPa / 2.50 bar / 36 PSI front (120/70ZR17 M/C (58W)) and 290 kPa / 2.90 bar / 42 PSI rear (180/55ZR17 M/C (73W)), paired with 4× NGK CR9EIA-9 spark plug(s) and a YTX9-BS battery.
Drain only: 3.3 L (3.49 US qt)
R 290 kPa (2.90 bar)
Est. Range: ~309 km (192 mi)

4. Generation Cutoffs & Real-World Wrenching Gotchas
Model-Year & Chassis Generation Notes
Replacing the heavy Z800 in 2017 (ZR900B, 795 mm seat, no TC), the 948cc Z900 gained KTRC traction control, LED lighting, TFT, and an 820 mm seat in 2020–2024 (ZR900F), then electronic throttle, IMU, and standard KQS in 2025 (ZR900P).
Oil & Clutch Mechanical Engineering Note
Tuned hotter than the retro Z900RS (111 hp) with 11.8:1 compression and 125 hp top-end rush, the Z900 takes 3.3 L drain-only or 3.8 L (4.0 US qt) with a 16097-0008 / HF303 spin-on filter using full-synthetic SAE 10W-40 JASO MA2.
Garage Wrenching Gotchas
- Standard Z900 trims run axial-mount Nissin 4-pot front calipers, whereas Z900 SE trims upgrade to radial Brembo M4.32 monoblocks—never mix up front brake pad part numbers between trims!
- Kawasaki’s Horizontal Back-Link rear shock sits directly above the exhaust pre-chamber; keep the linkage pivots clean of flung chain grit.
5. Frequently Asked Questions (FAQ)
What is the oil capacity and filter part number for the Kawasaki Z900?
Refill volume is 3.3 L (3.5 US qt) drain-only and 3.8 L (4.0 US qt) when replacing the 16097-0008 / HF303 spin-on filter.
Why do Z900 seat height specs vary between 795 mm and 820 mm?
Early 2017–2019 ZR900B bikes used a scooped 795 mm saddle, while 2020+ ZR900F models switched to a thicker, more comfortable 820 mm seat cushion (with an 800 mm low Ergo-Fit option).
What cold tire pressures and valve check interval apply to the Z900?
Cold inflation is 250 kPa (36 PSI) front and 290 kPa (42 PSI) rear, paired with a generous 42,000 km (26,250 mi) valve inspection interval.
