2018 Kawasaki Ninja 400 Maintenance Schedule, Oil Capacity & Service Parts
For the U.S.-market 2018 Kawasaki Ninja 400 and Ninja 400 ABS, change engine oil and the filter every 12,000 km (7,600 miles) or 1 year, whichever comes first, and service more often in severe use.

Maintenance schedule highlights
- Engine oil and filter: 12,000 km / 7,600 mi or 1 year; sooner for dusty, wet, muddy, high-speed or frequent start/stop use.
- Drive-chain lubrication: every 600 km / 400 mi, after wet-weather riding, or whenever the chain appears dry.
- Brake fluid: every 2 years.
- Brake hose and master-cylinder/caliper rubber: every 4 years.
- Coolant hoses and O-ring: every 3 years.
- Fuel hose: every 5 years.
- Pre-ride checks: oil, tires, chain, brakes, coolant, controls, lights and leaks.
Use mileage or time, whichever comes first. This summary does not reproduce the manual table and does not replace the correct owner or service manual.
Which kit should you choose?
Street/default: Motul 7100 10W-40 with HF303.
Street with racing-style filter: Motul 7100 with HF303RC; the service interval does not change.
Track/performance: Motul 300V Road Racing 10W-40 with either filter. Motul says the interval depends on use, so 300V never grants a longer street interval.
The product is a component-aware bundle: one live 4 L oil bottle plus one live filter. The 4 L bottle covers two documented 2.0 L filter-change fills before level adjustment; keep the unused oil sealed and never pour the entire bottle into the engine.
Other basic maintenance parts
Hiflofiltro identifies HFA2406 for the 2018 Ninja 400, but P4M does not have an exact live HFA2406 commercial record that passed this batch's gate. The manual specifies DOT 3 or DOT 4 front brake fluid and DOT 4 rear brake fluid, but brake fluid, coolant, chain care and drain-washer links remain omitted until exact live products pass the same audit.
