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 650R (the “n” 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 2018 in favour of the Kawasaki Z650.
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.

General information about the Kawasaki ER-6n
The Kawasaki ER-6n is an affordable bike that’s easy to ride and exceeds expectations for its budget price point.
The ER-6n is a member of Kawasaki’s parallel twin-powered family of middleweights. It’s powered by the same 649cc parallel twin water-cooled engine. It’s not an 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.
The 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.
A few things that make the ER-6n easy to ride are the lightweight clutch, neutral finder in the transmission, and very clear display.
