Kawasaki Ninja ZX-6R 636 (2013-today) Maintenance Schedule

The Kawasaki ZX-6R has been in production as a sports bike since 1995, and the ZX-6R has had 636cc capacity once before (in 2003-2007). After a five-year hiatus, Kawasaki resumed making the ZX-6R 636 in 2013, and that’s what this maintenance schedule is for.

The 2013+ Kawasaki ZX-6R 636 is based on a 636cc liquid-cooled inline four-cylinder engine. It has dual overhead cams, four valves per cylinder, and a high compression ratio of 12.9:1. All in, the 636 puts out a whopping 95 kW (130 PS / 128 bhp) at 13500 rpm, with even more power including ram air.

Since 2013, the ZX-6R has stayed largely the same, though in 2019 it got a new dash, standard quick shifter, and new style. The new ZX-6R also got traction control and ABS as an option (and standard in some markets), plus some other electronic aids.

While the 2013 model has remained the same until now, in 2019 the gearing was revised slightly to get it off the line quicker, with a one-tooth smaller countershaft sprocket. A quick-shifter was also added, as well as a facelift.

What you need to service the Ninja ZX-6R 636

To service your 636, you might need some basic maintenance tools. But apart from that, there are some specific parts you might need.

PartKawasaki Ninja ZX-6R 636 Spec
OilYou need 3.6L 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.

Don’t over-torque the drain bolt (spec is 29 Nm/21 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 49065-0024, or you can use a high-quality replacement item, the HF303. Torque for oil filter is 17.5 Nm (12.9 ft-lb) (use a torque wrench if needed).
Front brake padsGenuine part number for front brake pads is 43082-0131 for the 2017+ Ninja 636. Get double-sintered EBC brake pads for better bite and wear — code FA296HH.
Rear brake padsGenuine part number for rear brake pads is 43082-0133. Get double-sintered EBC brake pads for better bite and wear — code FA436HH.
Spark plugsNGK CR9E, with a spark plug gap of 0.7-0.8mm (use a spark plug gapping tool), torqued to 13 Nm or 9 ft-lb (use a torque wrench)
Air filterGenuine part number is 11013-0036. You can also use the K&N equivalent KA-6009.
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, e.g. Castrol DOT 4.
CoolantUse 2.5L (about 2.7 US qt) of 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.

About the Kawasaki Ninja ZX-6R 636 (2013+)

Kawasaki ZX-6R 636 green action on track knee down

The 2013+ Ninja 636 is the latest in a long-line of supersports motorcycles that people use for the roads.

The motorcycles in the ZX-6R line have always followed the same basic formula — a sports motorcycle with an inline four-cylinder 16-valve ~600cc engine with overhead cams and water cooling, driving the rear wheel via a chain.

What has changed over the years is the fuelling (evolving from carburettors to fuel injection), the exterior design of course, and the electronics keeping you upright. The ZX-6R has always been at the forefront with rider aids in its class, having ABS and traction control as options from 2013, and standard in many markets.

Most importantly, the ZX-6R is the one of the few 600cc class supersport motorcycle that’s still available new from Japanese dealers. As of 2021, Yamaha has retired the YZF-R6 from public life, and Honda’s 2021 CBR600RR isn’t available in most markets (and is expensive and exclusive where it is available). You can still get the 2011+ GSX-R600, but it’s about 25% down on power compared to the 636.

The Kawasaki ZX-6R has stayed alive by continuing to meet European emission requirements. Most recently, in 2019 Kawasaki revised the injectors to provide more fine atomization, letting the engineers set fuelling more precisely, and so tuning the engine to meet emissions with more precision.

Despite these updates to meet emissions standards, the latest ZX-6R 636 hasn’t lost power over the years. It still makes 95 kW (128 hp) at peak and has torque all through the torque curve, though naturally hitting peak torque over 8,000 rpm, and keeping it up there until around 13K. Do you want to rev to 13,000 rpm? You better be ready to, if you want to really feel what it’s like! By 12,500 rpm you’re already at over 100 km/h (65 mph), so the reality of most every-day riding is that you’ll probably short shift it a little (but prove me wrong!).

There are lots of reasons to not ride a sportbike. They’re uncomfortable, they’re highly strung, and they’re impractical. But the 636 is one of those motorcycles that takes those objections and casts them to one side and leaves you with nothing but a maniacal grin.

The Kawasaki ZX-6R 636 has a lot of other high-spec components. The suspension is fully adjustable, with Showa Big Piston SFF-style 41mm inverted cartridge forks up front. At the rear, the shock even has separate stepless high and low-speed compression damping, and adjustable ride height.

The brakes at the front are large 310mm petal discs with radial-mounted opposed 4-piston calipers.
