This is the maintenance schedule and associated service intervals for the Suzuki DR650SE, which people more often call the DR650S or just DR650 (which is what we’ll call it here).
The Suzuki DR650 is quite possibly the best all-around, dual-purpose motorcycle available … ever. Well, it’s one of a few, striking its own balance between off-road prowess and on-road practicality. It is a competitor to the Honda XR650L and also to the Kawasaki KLR650.
The DR650 is a thumper with a rock-solid reliable 644 cc air/oil-cooled four-stroke single cylinder engine carried in a strong steel, semi-double cradle frame. The telescopic fork and link-style rear suspension can tackle tough trails or urban roads.

What you might need to service the Suzuki DR650
To service your Suzuki DR650, you’ll need the following parts/consumables.
|Part||Suzuki DR650 spec|
|Engine oil||A bike like this isn’t fussy. The spec required is SAE 10W/40 oil rated at SE, SF, or SG under the API classification. Most oils meet this spec. Yamalube 10W-40 is a cheap and good quality option (there’s no Suzuki one but really brands don’t matter)|
|Oil filter||Use a Hiflofiltro HF137 for a good quality drop-in replacement.|
|Spark plug||Use a NGK CR10E gapped to 0.7-0.8mm.|
|Brake fluid||Use one of the appropriate spec, e.g. Castrol DOT 4.|
|Chain maintenance||Use either Motul chain paste or a Motul chain care kit if you need a brush, cleaner etc.|
|Grease||Use a lithium soap-based grease for external pivot points.|
|Air filter||You can usually clean the air filter. But if you have to replace it, use a K&N SU-6596.|
Suzuki DR650S Maintenance Schedule
Below is the maintenance schedule for the Suzuki DR650S.
The DR650 is a super easy bike to service. Valve clearance intervals of 24,000 km (14,500 miles), and there’s only one cylinder!
Notes on reading the maintenance schedule:
- I= Inspect and clean, adjust, replace or lubricate as necessary.
- R= Replace
- T= Tighten
- Interval: This interval should be judged by number of months or odometer reading, whichever comes first.

About the Suzuki DR650
The DR650 is the archetypical go-anywhere adventure bike.
In base form, it isn’t particularly capable as an adventurer. But it’s what it promises that is very different.
The DR650 is powered by an air/oil-cooled 644 cc thumper engine. There’s no liquid cooling system to complicate things, much less ride by wire or traction control just waiting to fail and leave you stranded.
The DR650 breathes through a Mikuni BST40 CV carburettor. It’s old-fashioned, but it’s also very fixable when the time comes to fix it.
The DR650’s big piston has a 100 mm bore and 82 mm of stroke, making it slightly oversquare, and the engine has a relatively low compression ratio of 9.5:1 — meaning it’ll be fine on any old gas. Final drive is via a five-speed transmission and chain drive.
The first Suzuki DR650 (of this kind, the DR650SE) was introduced in 1996, and while it has evolved since then, the more interesting thing is how much it hasn’t changed. The current DR650 is essentially the same as the original.
The engine may only put out 34 kW (46 hp) at peak, but you don’t really measure peak power for a bike like this. For a bike this light that is going to travel mostly off-road, it’s perfect. No wonder Suzuki hasn’t changed it in literally decades. (Also, any changes might make it run afoul of emissions regulations.
The front suspension is composed of 43mm KYB forks with gold anodized lower legs. The 1996+ DR650 also has an oil cooler, an electric starter system without a back-up kick lever (this is the E in the name DR650SE, by the way), and a small fairing.
The brakes on the 1996+ DR650 are composed of a single 290mm floating front disc and a 2-piston Nissin caliper. The rear is also a disc — no drums to fiddle with.
The DR650S definitely weighs in at the bottom of the range for true dual-sport machines at 166 kg (366 pounds) wet. This is partly due to its small gas tank — something many people upgrade for long-distance travel with dual overslung long-range tanks.
Maintaining the DR650 is very simple, since it has a mostly exposed engine and just one cylinder. Oil changes are every 3500 miles or 6000 km. And the recommended valve inspection period is a generous 3500 miles or 6000 km. Not bad for a simple air/oil-cooled bike.
