Suzuki DR650SE (1996+) Maintenance Schedule

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 ahve to replace it, use a K&N SU-6596.

About the Suzuki DR650

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

An air- and oil-cooled 644 cc thumper engine powers the DR650. No water jacket or radiator to complicate things, no fandangled contraptions like ride-by-wire or traction control just waiting to fail and leave you stranded on the road/trail/service department. The DR650 breathes through an old-fashioned, Mikuni BST40 constant-velocity carburetor.

The pistons measure 100 mm x 82 mm — typical for thumpers to run oversquare — and it runs a relatively low compression ratio at 9.5 to 1. A five-speed, constant-mesh transmission and chain drive complete the drivetrain.

The engine may only put out 34 kW (46 hp), but for a bike this light, and for this purpose (on-and-off-roading), it’s perfect. No wonder Suzuki hasn’t changed it in literally decades.

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.

Braking is through a 290mm floating front disc and a compact twin-piston Nissin caliper. The rear is also a disc, with a solid-mounted 245mm rotor and a single-piston Nissin caliper.

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. But it’s also due to frame revision. The frame for the DR650 was state-of-the-art 25 years ago, computer-designed to provide as much rigidity as possible while minimising weight. Same for the swingarm.
