This is the maintenance schedule with associated service intervals for the Kawasaki ER-6n.
The Kawasaki ER-6n is the naked sibling of the Ninja 650, a.k.a. the ER-6F (the “n” in ER-6n is for “naked”). It’s very much the same bike, just sans fairing!
Kawasaki has made the ER-6n since 2006, but only sold it in the US since 2009. It was retired in 2017 in favour of the Kawasaki Z650, which was updated at the same time as the Ninja 650.
The ER-6n is powered by a torquey 649cc liquid-cooled, DOHC, four-valve-per-cylinder parallel-twin engine. It’s the same engine that powers other similar motorcycles, like the Versys 650. It doesn’t set your hair on fire, but it’s an engine that most people can’t kill before they crash their bikes.

Maintaining Your Chain on the Kawasaki ER-6n
It’s important to maintain your chain on the ER-6n, particularly as these get used as commuters, which can be surprisingly high-stress. Use a good-quality chain lubricant like Motul chain paste, or a Motul chain care kit which comes with a couple of handy tools to maintain the chain.
Kawasaki recommends you follow the following chain maintenance schedule:
|Chain maintenance item||Every|
|Check drive chain lubrication condition, lubricating if necessary (Motul chain paste)||400 mi / 600 km|
|Check drive chain slack, adjusting if necessary||600 mi / 1000 km|
- Do these items (checking/adjusting slack, and checking/applying lubrication) more often if you ride your ER-6n in dusty or rainy conditions.
- Always lubricate the chain after washing the motorcycle.
Tyre size and tyre pressure for the Kawasaki ER-6n
The Kawasaki ER-6n has the following tyres and tyre sizes standard, as well as the following recommended tyre pressures.
|Wheel||Tyre size||Tyre pressure (cold)||Shipped tyre brands|
|Front||120/70 ZR17 M/C (58W)||225 kPa/32psi||DUNLOP SPORTMAX ROADSMART CQG|
|Rear||160/60 ZR17 M/C (69W)||250 kPa/36psi||DUNLOP SPORTMAX ROADSMART G|
General information about the Kawasaki ER-6n
The Kawasaki ER-6n is an affordable bike that’s easy to ride and which outperforms considering how cheap and simple it is.
The ER-6n is a member of Kawasaki’s parallel twin-powered family of middleweights. It’s powered by the same 649cc 180-degree parallel-twin water-cooled engine that powers the Ninja 650, Versys 650, and Vulcan S.
It’s not a terribly inspiring engine, but it makes torque everywhere you need it, and easily takes riders to speeds north of 180 km/h where a naked bike starts to feel like maybe it doesn’t belong (probably far below that for most mortals).
The Kawasaki ER-6n’s beauty is in its versatility. It’s near perfect as a commuter motorcycle — lightweight, simple, difficult to stall, easy to steer, and very, very reliable. In fact, I’ve never seen a ER-6n ruined through anything other than neglect or a crash.
The engine in the ER-6n will, if serviced, regularly go past 100,000 km (60,000 miles) without even sounding different. Many owners even forego valve inspections (but they really shouldn’t).
A few things that make the ER-6n easy to ride are the lightweight clutch, neutral finder in the transmission, and very clear display.
While the ER-6n only makes modest power, it’s still a popular choice for a track day bike as it’s so cheap to service, change tyres for, and (if necessary) replace if it’s totalled. It’s tempting for new owners to replace the exhaust, but the reality is that the first modifications you should make to the ER-6n, if you planning on pushing it hard, are to the suspension and brakes.
