Kawasaki Vulcan 750 (1985-2006) Maintenance Schedule and Service Intervals

This is the maintenance schedule with associated service intervals for the Kawasaki Vulcan 750.

The Kawasaki Vulcan 750 is a small-bore cruiser that Kawasaki first introduce in 1985 and made largely unchanged for over two decades.

The core of the Vulcan 750 is a 749cc liquid-cooled carburettor-fed DOHC 8-valve V-twin — a quite advanced engine for a cruiser. It makes modest peak power of 49 kW (66 hp), with a very flat torque of 62 Nm (47 ft-lbs) through its modest torque range.

The engine runs a mild compression ratio of 10.3:1 and is very reliable.

Final drive is a 5-speed transmission and a shaft drive.

Over its long lifespan, the Vulcan 750 hardly changed. The maintenance schedule below came from one of the more recent manuals but applies to all models, with only minor changes in the past but nothing significant.

From 2006 the Vulcan 750 was replaced by the Vulcan 800.

About the Kawasaki Vulcan 750

Kawasaki Vulcan 750 hi-res lhs 1

The Kawasaki Vulcan 750 is an iconic classic cruiser, and the first of the iconic Vulcan line that has spawned machines all the way from tiny bikes to the massive Kawasaki Vulcan 2000.

Kawasaki first launched the Vulcan 750 in 1985. It was the first cruiser Kawasaki launched with a V-twin engine.

Given the classic cruisers that Kawasaki has made since, including the iconic Nomad series, the Vulcan 750 was quite a humble start. But it had many elements that made it to later motorcycles.

The Kawasaki Vulcan 750’s was thoroughly modern — especially for the time. The engine is a liquid-cooled 749cc V-twin, already unconventional in cruisers for being small in capacity and having liquid cooling.

But it goes further. It also has dual overhead cams and four valves per cylinder (making it an 8-valve engine). Despite this, the Vulcan 750 has hydraulic valve lash adjusters, which means you never have to adjust the valves — you’ll notice it’s not a line item in the Vulcan 750’s maintenance schedule.

The engine is rubber mounted within the steel frame, meaning the Vulcan 750 has quite a smooth and vibration-free ride.

Finally, the final drive in the Vulcan 750 is a shaft drive. You just have to keep the lubricant topped up and replace it every now and then and you basically have a very, very low-maintenance cruiser.

Like most cruisers, the ride gear on the Kawasaki Vulcan 750 is simple, but not excessively so. There’s non-adjustable front suspension, though at the rear you can adjust the rear shocks for not just preload but also rebound damping.

At the front, there’s not just one (like on most cruisers) but two disc brakes. Maybe Kawasaki thought people would ride the Vulcan 750 hard!

After 2006, Kawasaki replaced the Vulcan 750 with the Kawasaki Vulcan 800.
