Kawasaki Ninja 650 (ER-6F, 2006-present) Maintenance Schedule and Service Intervals

Kawasaki Ninja 650 KRT

This is the maintenance schedule with associated service intervals for the Kawasaki Ninja 650, also known as the ER-6F or EX650, and previously known as the Kawasaki Ninja 650R.

The Kawasaki Ninja 650/ER-6F is a parallel twin motorcycle with a fairing. It’s the sportier stablemate of the naked ER-6N, which is otherwise identical. They even both have handlebars, which is quite unusual for a motorcycle with a fairing.

The Kawasaki has gone through a few major updates since launch in 2006.

  • 2006 Ninja 650R: First launch of the Ninja 650R; not yet introduced into the US market.
  • 2009 Ninja 650R: Engine unchanged but revised tuning for better response and mid-range power, and improved cooling. Externally redesigned with sharper contours, more flexible chassis and stiffer swingarm, rubber engine mounts, new dash (with fuel level sensor), and less buzz in the handlebars and fairing. Introduced to the US.
  • 2012 Ninja 650 (loses the “R”): Two-piece seat, wider handlebars, and new tachometer + LCD showing speed, trip meters, fuel consumption etc.
  • 2017 Ninja 650: New trellis frame, lighter weight, better handling, removing the side-mount rear shock, and adding a slipper clutch

During the years, almost nothing has changed with the engine — though a few parts have (e.g. the air filter). Those are noted below.

What you need to service the Kawasaki Ninja 650

If you’re servicing the Kawasaki Ninja 650, firstly, you might need these common motorcycle maintenance tools (thinks like an oil filter wrench, catch pan, etc.).

But aside from that, you’ll need these specific items to maintain the Kawasaki Ninja 650.

PartKawasaki Ninja 650 Spec
OilYou need 1.8L (1.7 US qt) of SAE 10W-40 engine oil “with API SG, SH, SJ, SL or SM with JASO MA, MA1 or MA2 rating”, preferably Kawasaki 10W-40 Engine Oil.

Kawasaki oil grade recommendation
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 filterOil filter is part 16097-0008, or you can use Hiflofiltro HF303RC. Torque for oil filter is 17.5 Nm (12.9 ft-lb) (use a torque wrench, and it’s easier on the K&N one)
Front brake padsYou can get original OEM parts from a dealership, or double-sintered EBC brake pads for better bite and wear. Part numbers are:
* Years 2006-2016, Left hand calliper: FA229HH, Right hand calliper: FA231HH
* Years 2017+: FA226HH (both callipers)
Rear brake padsAs with the front brake pads,yYou can get original OEM parts from a dealership, or double-sintered EBC brake pads for better bite and wear. EBC part number is:
* Years 2006-2016: FA192HH
* Years 2017+: FA174HH
Spark plugsNGK CR9EIA-9, with a spark plug gap of 0.8-9.0mm (use a spark plug gapping tool), torqued to 13 Nm or 9 ft-lb (use a torque wrench)
Air filterKawasaki changed the air cleaner during the evolutions of the Ninja 650R/Ninja 650. Part numbers are below. DNA also makes performance air filters for later models, and their part numbers are here too.
* 2006-2008: 11029-0008, P-K6N06-01 — this is a user-cleanable item
* 2009-2011: 11029-0011, P-K6N09-01
* 2012-2016: 11013-0713, P-K6N12-01
* 2017-2021: 11013-0745, P-K6N15-01
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 like Castrol DOT 4.
CoolantUse nitrate-free, phosphate-free, 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 650

The Kawasaki Ninja 650 is an amiable motorcycle that can be called in for commuter and touring duties at a moment’s notice. The twin-cylinder motor has ample torque, making it easy to go fast in the real world of public roads. The highly visible off-center spring-preload adjustable rear shock gives the Ninja 650 a unique look.

The Kawasaki Ninja 650 is propelled by a strong and compact 649 cc, liquid-cooled, DOHC, 8-valve parallel-twin engine that’s almost un-killable. Its modest power (50 kW/63 hp) is driven to the ground by a modern six-speed transmission that helps you make smooth and precise shifts.

The stopping power is assured by dual 300m petal-style discs w/ 4-piston calipers and a 220mm petal-style rotor w/ 2-piston caliper.

The Ninja 650 has been a favourite of many kinds of riders, including

  • People who want a mildly sporty middleweight for everyday commuting
  • Beginner riders (in the US, where people can ride anything, or in the UK, Europe, or Australia in A2 or LAMS-friendly de-tuned format)
  • Some track riders, who improve the suspension and now have an unkillable and very learner-friendly motorcycle

The latest KRT Edition of the Ninja 650 looks really nice, too — See the pics above!

The 2020 edition of the Kawasaki Ninja 650 gets a couple of updates to bring it into the modern era. Visually it gets the KRT livery, with bodywork that’s as clean as that on the latest ZX-10R. It also gets a color 4.3-inch TFT display, with multiple display modes, to show you a little or a lot of information.

The Ninja 650 isn’t as heavy as it used to be, either. Fully loaded with oil and gas it weighs 190 kg (423 lb), which is very reasonable.
