This is the maintenance schedule and associated service intervals for the Suzuki GSR750.
Suzuki released the GSR750 in 2011 and produced it until 2016, when it was replaced by the GSX-S750 was announced.
The GSR750 is an upright standard motorcycle with an engine from the K5 GSX-R750, but retuned for (even) more mid-range performance. The engine still has quite a bit of punch though, with peak power of 78 kW (105hp) — but it’s a far cry from the extreme levels of the GSX-R.
Like many other standard equivalent of sportbikes, the Suzuki GSR750 has a few simpler components to keep the price down — like less adjustability in the front suspension. And considering it has been stripped back, it’s not as light weight as you’d expect, weighing 210 kg (463 lb) fully fuelled. But it does come with ABS, a feature the GSX-R750 never had.

What you need to service the Suzuki GSR750
If you’re going to service your motorcycle, you should start with some basic motorcycle maintenance tools.
But once that’s taken care of, there are a few basics you need to keep your GSR750 in order.
|Part||Suzuki GSR750 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 another popular multigrade synthetic oil like Motul 5100.|
|Oil filter||Use a Hiflofiltro HF138RC, which is a drop-in high-quality replacement that you can undo with a regular wrench.|
|Air filter||Use a K&N air filter SU-6006, used on a couple of other Suzuki motorcycles.|
|Spark plugs||The standard spark plug is NGK CR9EIA-9. (Remember, you need four!)|
|Brake fluid/Clutch fluid||Suzuki (like most motorcycles) requires DOT 4 brake and clutch fluid.|
|Coolant||Suzuki 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 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.|

About the Suzuki GSR750
The Suzuki GSR750 is a commuter bike, a comfortable upright bike that’s nevertheless all most people need for their daily adrenaline rush on the way to work.
Unlike its sibling the GSX-R750, which gets into the redline area at 14,250rpm (with a hard stop at 16K, the GSR750 has a much more palatable 10,625 (I think?) rpm redline, with the party over at 13K.
The whole engine is tuned like this, to optimise for torque down low, sacrificing quite a lot of power up top — unlike the GSX-R750’s near 150 hp at the crank, the GSR750 makes a maximum of 105hp (78 kW), with peak power just short of the redline.
Otherwise, the GSR750’s 749cc engine has a lot in common with its sportier sibling. It’s still a 4-stroke, 4-cylinder, liquid-cooked DOHC engine with electronic ignition. And it’s efficient, giving a user around 60 mpg or 4L/100km.
The engine’s revisions (vs the GSX-R750) include cam profiles, intake and exhaust tracts and a somewhat less aggressive 12.3:1 compression ratio. The result is broad low-end torque and enough mid-range power for strong acceleration, and great throttle response for a street bike.
With adjustable brightness, the GSR750’s instrument cluster has a prominent, easy-to-read analogue tachometer and a large digital LCD speedometer. The LCD display also includes average fuel consumption meter, gear position indicator, fuel gauge, odometer/trip meter and a clock.
The GSR750 is fitted with 17 inch aluminum rims which are wrapped in 120 and 180 profile tyres, surprisingly sporty for what’s essentially a commuter.
