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.
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.|

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 kgf/cm2, 36 psi)|
|Rear||130/70-17M/C 62H||290 kPa (2.90 kgf/cm2, 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.
It has an air-cooled parallel twin-cylinder engine with 487cc derived from the earlier GS450.
On top of that, the transistorised electronic ignition and precise carburettor also help in keeping the engine to run as smoothly and as efficiently as possible.
Suzuki also produced GS500 models, identified by 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.
A two-into-one exhaust system adds invigorating note to the engine’s distinct pulses, yielding a good power delivery. Suzuki Pulsed-secondary AIR-injection (PAIR) system effectively keeps emissions low. Front telescopic forks and a rear monoshock absorber give a good balance between sportiness and comfort.
Other features of the GS500:
- Easily accessible seven-way preload adjuster of rear suspension allowing quick tailoring to rider’s preference.
- Front disc brake with two-piston caliper and rear disc brake provide excellent stopping power.
- Well-padded seat with enough seating space and comfortably positioned handlebars for easy in-town riding.
- Smooth seat surface for the rider to move around easily.
- 20-liter fuel tank, together with excellent engine fuel economy, means ample touring range.
- User-friendly features include comprehensive instrument cluster, convenient center stand and frame-mounted one-piece grab bar.
- Black-painted double-cradle frame, dark-silver engine finish and upswept tail section are visual reminders of the GS500’s sportier stablemates.
