Kawasaki Ninja ZX-9R (1994-2003) Maintenance Schedule and Service Intervals

This is the maintenance schedule with associated service intervals for the Kawasaki Ninja ZX-9R.

The Kawasaki Ninja ZX-9R is a motorcycle in the Ninja sport intended for on-road riding, produced from 1994 until 2003. There were five model iterations over the years.

The major changes were

  • 1994-1995 (ZX900B, ZX900B2): Original versions, with fully adjustable upside-down KYB 43mm forks and remote-reservoir KYB monoshock. Brakes were four-piston Tokico front calipers on 320mm front discs. Induction was through a 10-litre airbox fed by dual ram-air intakes.
  • 1996-1997 (ZX900B3, ZX900B4): Brakes improved to six-piston Tokico front calipers. The rear suspension was improved, and power got a slight bump.
  • 1998-1999 (ZX900C1, ZX900C2): Other than the engine, all new. Hydraulic clutch, lighter wheels, lighter brake discs (but same brakes), new 46mm right-way-up KYB forks, and improved rear shock.
  • 2000-2001 (ZX900E1, ZX900E2): All new twin headlight look, and many small improvements made to improve handling
  • 2002-2003 (ZX900F1, ZX900F2): New Nissin four-piston calliper brakes and 320mm discs, rear swingarm and shock changes to improve handling, and new carburettors.

What you need to service the Kawasaki ZX-9R

PartKawasaki ZX-9R Spec
OilYou need 3.3L (3.5 qt) of SAE 10W-40 engine oil “with API SE, SF, SG, SH, SJ, with JASO MA rating”, preferably Kawasaki 10W-40 Engine Oil.

Don’t over-torque the drain bolt (spec is 20 Nm/15 lb-ft per the manual) — use a torque wrench if you don’t have experience with how much torque is enough.
Oil filterOil filter is part 16097-0008, or you can use K&N KN-303. Torque for oil filter is 10 Nm (7 ft-lb) (use a torque wrench, and it’s easier on the K&N one)
Front brake padsFor the front brake pads, an easy upgrade is double-hardened EBC brake pads, which give great bite and fade resistance. Pay attention to which model you have, as the brakes changed.
* B1-B2 (four-piston Tokico calipers): FA158HH
* B3-B4, C1-C2, C3-C4 (six-piston Tokico calipers): FA188HH
* F1-F2 (four-piston Nissin calipers): FA347HH
Rear brake padsFor the rear brake pads, a good-quality and easy-to-obtain option is EBC FA192HH (for all model years).
Spark plugsNGK CR9EK, with a spark plug gap of 0.7-0.8mm (use a spark plug gapping tool), torqued to 13 Nm or 9.4 ft-lb (use a torque wrench)
Air filterThese days it’s easier to get K&N replacements. Parts:
* B1-B4: KA-9094, OEM 11013-1232
* All others: KA-9098, OEM 11013-1270
Cable lubricantRemember to lubricate your clutch cable (and brake cables if you have them) with a cable lubricant. Protect All Cable Life is a good general-purpose lubricant.
Chain lubricantThe chain needs to be lubricated every 600 km/400 miles (or more, if it gets wet/dirty). Motul chain paste is cheap and well-loved.
Brake fluidSpec is to use DOT-4 brake fluid.
CoolantUse “green” 50/50 ethylene glycol-based coolant with anti-corrosion inhibitors, e.g. Valvoline Zerex G05.
GreaseUse a lithium soap based grease for all the important greasing points.

General information about the Kawasaki Ninja ZX-9R

The ZX-9R has an 899 cc, transverse four-cylinder, four-stroke engine, fed by carburettors through its whole lifetime. The frame used on the ZX-9R is a lightweight aluminum twin-spar item.

The ZX-9R combines open-class power, sharp 750 superbike handling, and comfort the competitors couldn’t match. Over the years, the power kept improving and the weight kept dropping, to the point where the 2002-2003 model made , vs 104 kW (139 hp) on a wet weight of 242 kg (533 lb) in the original
