Kawasaki W650 Maintenance Schedule and Service Intervals

This is the maintenance schedule with associated service intervals for the Kawasaki W650.

The Kawasaki W650 is a retro classic motorcycle made between model years 1999-2007 and superseded by the Kawasaki W800, although the W650 is the true classic according to many fans.

The W650 has a long-stroke engine with an anti-vibration balance shaft and modern electronics — apart from the carburettor. It has air-cooled SOHC, 8-valve vertical twin 676 cc engine with 360-degree crankshaft design, much like the Triumph Bonneville.

Kawasaki made no significant updates to the W650 during its production run so this maintenance schedule is the same for the whole series.

General information about the Kawasaki W650

The Kawasaki W650 has reached classic status. It has an iconic simple design, which many modern owners would say “hey, that looks like a Bonneville!”. But the truth is, Kawasaki has been making old-school standards since as long as Triumph has, and well before Triumph made retro replicas in its modern factory.

The W650 is really a simple motorcycle. No fuel injection, no ABS, and with a fully exposed engine — it’s super easy to work on, polish, and improve. That’s why it’s getting so popular. In an age where motorcycles are judged by the quality of their on-board entertainment systems, the Kawasaki is judged by the shininess of its paint, the brightness of the chrome, and the fact that the engine doesn’t spring sudden oil leaks like its design contemporaries.

The W650 is also modestly powered. Having a fairly low 31.5-inch seat height, it’s a popular first bike, or a popular one to turn into a flat tracker or a scrambler. In many jurisdictions (like the UK or Australia), it’s learner legal — though because it’s an increasingly expensive motorcycle due to collectable value, not a great first bike.

The Kawasaki W650 has a 31.5-inch seat height, a four-gallon tank, and a comfortable reach to the bars with a squishy seat and footpegs.

Unable to meet new emissions standards, Kawasaki ended W650 production in 2008. It was replaced by the fuel-injected Kawasaki W800, which is great, but which never quite picked up as much steam.
