Kawasaki Vulcan 900 (2006-present) Maintenance Schedule and Service Intervals

2020 Kawasaki Vulcan 900 Classic Stock Image

This is the maintenance schedule with associated service intervals for the Kawasaki Vulcan 900, including the Classic.

The Kawasaki Vulcan is an easy-going but classy cruiser motorcycle. The Vulcan range goes from tiny (125cc) all the way to massive (2000), so 900 sits roughly right in the middle. Despite being a little old-tech (no ABS!), the Vulcan 900 is still being made today (as of 2021, anyway), with no mechanical changes since 2006 other than tweaks.

The Kawasaki Vulcan 900 Classic is a mid-sized motorcycle cruiser, first introduced in 2006. It is powered by a liquid-cooled 903 cc V-Twin engine, with a five-speed transmission, putting power down through a belt drive.

For a while the Vulcan 900 had its own category, before the mid-size Yamaha Bolt came along.

What you need to service the Vulcan 900

Here’s a shopping list of replaceable items you need to service the Kawasaki Vulcan 900.

PartKawasaki Vulcan 900 Spec
OilYou need 3.2L (3.4 US qt) (when the filter is removed) 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 20 Nm/14.5 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 16097-1058, or you can use HF303RC. Torque for oil filter is 18 Nm (13 ft-lb) (use a torque wrench, and it’s easier on the K&N one)
Brake padsEveryone on the Vulcan forums recommends double-sintered EBC brake pads. They’re cheaper and better. You need FA229HH for the front and FA231HH for the rear.
Spark plugsNGK CPR7EA-9, with a spark plug gap of 0.8-0.9mm (use a spark plug gapping tool), torqued to 18 Nm or 13 ft-lb (use a torque wrench).
Air filterGenuine part number is 11013-0015. You can also use the K&N equivalent KA-9006.
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.
Belt tension toolUse this tool to check that the belt tension is within spec.
Brake fluidSpec is to use DOT-4 brake fluid.
CoolantUse nitrate-free, phosphate-free, ethylene glycol-based coolant with anti-corrosion inhibitors, e.g. Valvoline Zerex G05
GreaseUse a lithium soap-based grease and silicone grease for all the important greasing points.

Maintenance Schedule for Kawasaki Vulcan 900

Below is the maintenance schedule for the Kawasaki Vulcan 900.

The following is the list of maintenance operations and to be done on this motorcycle with a time or distance interval — whichever comes earlier.

For convenience, I’ve rounded the converted mileages. Nobody does a service at 15,200 miles (it’s not that precise!) — I’ve written it in as 15,000.

  • K: Per Kawasaki “Should be serviced by an authorized Kawasaki dealer”
  • #: Service more frequently when operating in severe conditions: dusty, wet, muddy,
    high speed, or frequent starting/stopping.

General information about the Kawasaki Vulcan 900

The Kawasaki Vulcan 900 has a 903cc V-Twin SOHC Engine tuned to deliver lots of torque from low rpm.

The Vulcan 900 is both liquid and air-cooled, with finned cylinder heads. It helps maintain consistent engine temperatures in a variety of conditions.

The Vulcan 900 has a number of features that make it more modern than rattly cruisers of the past. These include

  • Rubber engine mounts to reduces excess engine vibration
  • Positive neutral finder to help find neutral at a stop
  • Fuel injection with dual throttle bodies. The sub throttles, located behind the main throttle valve, are controlled by the ECU so that the fuel injection system retains a more precise throttle response, similar to a constant velocity carburetor.
  • Twin disc brakes

The Vulcan 900 has a very low 26.5-inch seat height that lets even shorter riders easily plant both feet on the ground at stops.
