Suzuki GSX-S750 (2015-present) Maintenance Schedule and Service Intervals

This is the maintenance schedule and associated service intervals for the Suzuki GSX-S750, made from 2015-present. It’s an evolution of the GSR750.

The Suzuki GSX-S750 is a middleweight standard sport bike based on the GSX-R750, using the same base engine made since 2005 — a cracker that has only been improved with fuelling and electronics with age (though not everyone likes all the electronics).

Like many “standard” versions of high-power sport bikes, the GSX-S750’s engine is re-tuned for mid-range torque at the expense of high-end power. But it’s still a firecracker, producing 84 kW (112 hp) — plenty for a standard bike in most situations.

The bike is still quite sporty in design, with a streetfighter stance that still encourages you to bend over a bit, not sit upright like on a Bonneville. And there are other sporty aspects to it too, like twin wave front rotors and inverted cartridge forks, though they’re only adjustable for pre-load.

What you need to service the Suzuki GSX-S750

Apart from basic motorcycle maintenance tools, you will need the following consumables specific to the GSX-S750. The following are from the service manual, user manual, and online reference charts.

PartSuzuki GSX-S750 spec
OilSuzuki 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 another popular high-grade oil like Motul 300V or Motul 7100.
Oil filterUse a Hiflofiltro HF138RC, which is a drop-in high-quality replacement.
Air filterUse a K&N air filter as a drop-in replacement, part number SU-6006.
Spark plugsThe standard spark plug is NGK CR9EIA-9 (you need 4 for the GSX-S750)
Brake fluid/Clutch fluidSuzuki (like most motorcycles) requires DOT 4 brake and clutch fluid.
CoolantSuzuki only requires a coolant that’s “compatible with an aluminium radiator”. Most motorcycle coolants are, and so a Valvoline Zerex G05 is a fine option.
Chain maintenanceUse either Motul chain paste or a complete Motul chain care kit for frequent chain servicing.
Brake padsThe Suzuki GSX-S 750 uses these brake pad part codes for EBC double-hardened pads:
* Front, Non ABS: FA229HH/FA231HH (Left/Right)
* Front: ABS: FA347HH x 2
* Rear (ABS or not): FA174HH
GreaseAlways handy to have some lithium soap-based grease for external pivot points, like the kickstand.

The GSX-S750 is an evolution of the GSR750, and has the same core principle — take the GSX-R750 and make it more street usable, without sacrificing too much.

Inherited directly from a GSX-R supersport machine, the powerful 749 cc four-cylinder fuel-injected engine is specially tuned and refined to maximize its potential on the streets and on winding roads.

The GSX-S750 inherits a lot of cutting-edge technology from the legendary GSX-R series, including the engine management system, the downdraft double-barrel Suzuki Dual Throttle Valve (SDTV) system for efficient and smooth combustion, both of which deliver a highly controllable power delivery throughout the engine’s broad power range.

Suzuki’s digital ignition system, Idle Speed Control (ISC) and the use of iridium spark plugs contribute to linear throttle response, greater low-end torque production, easier engine startup, lower cold-start emissions, and more stable idling.

Engine speed is controlled to ensure it doesn’t drop below what is necessary to maintain a smooth idle. Low RPM Assist also monitors engine speed, enabling the rider to operate the clutch lever and pull away without opening the throttle. This helps make negotiating busy city streets smoother and easier. Traffic jams are the GSX-S750’s jam. It’s not sexy, but it’s realistic for many.

The track-bred ride aids provide greater confidence and reduces fatigue by delivering control over engine output that helps prevent rear wheel slip or spin. The ABS and traction control systems operates so smoothly and naturally that they don’t interfere with handling, even when you want to engage in aggressive sports riding.

You can choose one of three ride modes using the convenient handlebar switch:

  1. Mode one is for sport riding with minimal intervention
  2. Mode two offers the ideal balance for typical road conditions; and
  3. Mode three delivers maximum traction control when riding in poor conditions.
