This is the maintenance schedule and associated service intervals for the Suzuki GS500, also applying equally to the Suzuki GS500F, which is the same motorcycle but with a fairing.
The Suzuki GS500 is an entry level motorcycle with a 487cc parallel twin that’s air-cooled and carburettor fed. It’s a very simple motorcycle, and maintenance is very straightforward (in fact, this is a great motorcycle to learn how to do maintenance on, particularly the non-faired version).
Suzuki produced the GS500 and GS500E from 1989 on and the fully faired GS500F from 2004 on. They were both retired, being replaced conceptually by fuel-injected motorcycles like the Ninja 650.

Service intervals of the Suzuki GS500
The Suzuki GS500 has 3500 mile / 6000 km or annual service intervals. At every interval, you have to not just change the oil and filter, but also inspect the valve clearances.
Suzuki requires you to replace the spark plugs and air cleaner every second service. They also suggest you clean the air filter between services, particularly if your ride in the rain or in dusty conditions.
Since the Suzuki GS500 has an air-cooled engine, you don’t have any coolant to change, but you should still keep the brake fluid fresh.
What you need to service the Suzuki GS500
Aside from basic motorcycle maintenance tools, you need a number of specific items to service the GS500 (or GS500F).
|Part||Suzuki GS500 spec|
|Oil||Suzuki requires engine oil with JASO MA spec, or at least API SF/SG or SH/SJ spec. Many oils fit this. Suzuki recommends SAE 10W-40 weight Suzuki motor oil, but I wouldn’t over-think this and use a basic synthetic like Motul 5100.|
|Oil filter||Use a Hiflofiltro HF133, which is a drop-in high-quality replacement.|
|Air filter||Use a K&N air filter as a drop-in replacement, part number SU-5589. You can clean the replacement air filter rather than replace it.|
|Spark plugs||The standard spark plug is NGK DPR8EA-9, gapped at 0.8-0.9mm.|
|Brake pads||Get EBC FA231HH brake pads for the front, and FA63HH for the rear.|
|Brake fluid/Clutch fluid||Suzuki (like most motorcycles) requires DOT 4 brake and clutch fluid.|
|Chain maintenance||Use either Motul chain paste or a complete Motul chain care kit for frequent chain servicing.|
|Grease||Always handy to have some lithium soap-based grease for external pivot points, like the kickstand.|
Suzuki GS500 Maintenance Schedule
Below is the maintenance schedule for the Suzuki GS500.
- Intervals should be judged by number of months or odometer reading, whichever comes first.

Tyre size and tyre pressure for the Suzuki GS500
The manual for the GS500 specifies the following tyre sizes and pressures. The manual also mentions Bridgestone Battlax tyres, but the specific version (BT45) isn’t mandatory or even necessarily easy to get.
|Wheel||Tire size||Tire pressure|
|Front||110/70-17M/C 54H||250 kPa (2.50 bar, 36 psi)|
|Rear||130/70-17M/C 62H||290 kPa (2.90 bar, 42 psi)|
About the Suzuki GS500
The Suzuki GS500 is an excellent first bike, with adequate if not exciting power for more experienced riders (approximately 40 HP at the rear wheel). In the motorcycle market, the GS500 occupied the low end of Suzuki’s mid-sized range for over twenty years.
Suzuki sold the unfaired version of the GS500 from 1988 in the UK, and from 1999 in Europe and North America.
The GS500 has an air-cooled parallel twin-cylinder engine with 487cc derived from the earlier GS450. It’s carburettor fed, but has electronic ignition.
Suzuki also produced GS500 models identified with a ‘U’ suffix with engines restricted to satisfy the maximum power-to-weight ratio for use in countries where restrictive motorcycle licenses were issued, like the EU and UK. But these days, the GS500 meets restriction requirements of most countries, including Australia / New Zealand’s updated LAMS rules.
The parallel twin of the Suzuki GS500 isn’t high on power, but it has a distinct burble to it. Suzuki’s two-into-one exhaust system doesn’t strangle it and lets the engine breathe enough for a nice sound and an even torque curve.
Front suspension of the GS500 is via a non-adjustable telescopic fork, and the rear shock is adjustable for preload via a seven-way adjuster.
Brakes are simple but effective, with a single 320 mm disc and two-piston caliper.
The GS500 has a classic console and instruemnt cluster, with a tachometer that rises to an ambitious 10000+ RPM, and a speedometer that goes to over 200 km/h (over 120 mph). You’ll get most of the way there!
