| I
have tried to tell the Suzuki DR-Z 400 model history on this page
as I know it. This page is still under construction.
I would be grateful of any contributions sales brochures, magazine ads,
magazine articles, pictures, specs, facts, corrections etc. Please scan the material
in JPEG format (large enough that all the details are visible) and send
them to me. Please tell me the source and the publication date if possible.
If you send me pictures of your own bike, please follow these

| 2000 Suzuki DR-Z400S, Champion Tellow (YU1) |


2000 Suzuki year code: Y


Suzuki DR-Z400, released in April 2000, was completely different than the DR350 that Suzuki introduced to the world for the 1990 model year. Three different models was offered; the DR-Z400 with a kick start, the DR-Z400E with an electric starter and the road legal DR-Z400S with lights, flashers, mirrors and smoother tyres for road use.
The DR350 was the first new Suzuki thumper designed strictly for dirt duty since 1980. In addition, Suzuki also listened to their customers begging for barely street-legal dual-purpose bikes and also introduced the DR350's dual-sport brother, the DR350S. While not exactly what hard-core dirt riders clamored for, it was nonetheless a decent bike for the majority of buyers and could be fairly easily modified for better off-highway performance.
As competent a trail bike as the DR350 was, it began to get overlooked as other thumpers came onto the scene. Every other company developed their own up-to-date four-strokes. Suzuki needed a new model to meet the competition.
The rumors suggested a liquid-cooled 400 housed in an RM250 frame. And it turns out the rumors weren't too far off.
The new DR-Z400 is indeed a liquid-cooled 400 with a pair of cams in the four-valve head and a very oversquare bore-and-stroke configuration of 90.0 x 62.6mm for 398cc of actual displacement.
Suzuki relied on its sportbike technology, transferring much of it to the DR-Z. The Twin Swirl Combustion Chamber (TSCC) comes from the four-cylinder GSX-R, as does the shim-under-bucket valve lash adjustment and narrow valve angle. Suzuki's proprietary SCEM (Suzuki Composite Electrochemical Material) plates the cylinder's bore with a nickel-silicon-phosphorus-carbide combination that is much lighter and better at transferring heat than a conventional cast-iron liner. In addition, the motor also uses a 2.0-quart dry-sump oiling system (as did the old DR350), which also helps keep the cases compact.
The DR-Z400 comes with Keihin's 39mm FCR-series carburetors. Not only does it have an accelerator pump (which squirts a bit of raw fuel into the carb at low rpm to avoid the dreaded four-stroke stumble), it utilizes a Throttle Position Sensor similar to the YZ-F. Tied into the digital ignition system, it helps determine the optimum spark timing for a given rpm, depending on how far the slide is opened. The kickstart-only DR-Z400's Keihin also sports a hot-start button similar to that of the YZ-F that you pull to make starting a warm engine easier, especially if you stalled it.
There are a few other differences between the kickstart DR-Z400 and the dedicated electric-start version, the DR-Z400E. In order to accommodate the starter paraphernalia, the E model's crank is slightly longer on the left side, necessitating a minimally larger ignition cover. The 12-volt, 6.5-amp maintenance-free battery is a compact and light. The three-phase charging system puts out plenty of juice, with 150 watts of maximum power on the 400 and 200 watts max from the 400E. And since the E model comes with only a button for starting, don't leave the key on or you'll quickly run that gel-cell battery down and find out just how difficult it is to start a 400cc thumper that has no kickstarter or manual compression release (both come on the regular 400). For the best of both worlds, Suzuki offered a kit which will let you fit a kickstarter and the manual decompresser to a 400E.
As for having an RM-spec chassis, well, it's not true. Both the DR-Z and RM use chrome-moly tubing with aluminum subframes and run the swingarm pivot through the rear of the cases, but the four-stroke's frame is specific to the DR-Z. Suzuki's design goal was to keep the bike as compact and narrow as possible. Indeed, the DR-Z feels quite slim. It sports 27.3 degrees of rake with 112mm (4.42 inches) of trail and 1 475mm (58.1 inches) between the axles; not particularly extreme but directed at nimble steering with more than a semblance of stability.
The suspension is different than a RM's. In front is a 49mm Showa conventional cartridge fork with 288mm (11.3 inches) of travel. RMs came equipped with inverted forks. At the rear you find an aluminum-bodied, piggyback reservoir Showa shock that lets the wheel swing through a claimed 295mm (11.6 inches) of travel. Both suspension units feature clicker-adjustable compression and rebound damping, 18 clicks of both compression and rebound in front and 26 clicks of compression and 21 clicks of rebound in back. The shock's 5.3 kg/mm spring has the standard threaded collars for preload adjustment. There are no such external adjusters for the 0.44 kg/mm fork springs.
Both brakes utilize RM calipers, but the carriers and rotors are different.
