Following the evolution of its bigger sibling (the Suzuki DR650SE), the Suzuki DR-Z400S remains visually unchanged for 2010, but ads a few distinctive touches in order to stand out by its own. Mechanically, the new DR doesn’t feature any late additions worth to brag about, so it remains the same bulletproof built machine on the trails and a docile commuter when not on them.

2010 Suzuki DR-Z400S

When deriving the DR-Z400S from their middleweight dual-sport bike, Suzuki made the smart choice of liquid-cooling the DOHC engine, something that would prove terribly effective on the long run. The best proof is the 2010 model year, which makes use of that very same engine also the “SM” model.

Due to the user-friendly approach and versatile character, the bike is the choice of many riders who plan to use it for practical purposes or simply have fun on the trails and it makes it with no scratch in any situation.

2000 Suzuki DR-Z400S

The Suzuki DR-Z400S started life together with the new millennium and it was built to last, both on the market and on tough roads. It had where to inspire, so it featured modern looks and Suzuki’s 2000 model year colors (Blue, Yellow and Black). As I mentioned before, the key was its engine, but it did had a disadvantage: the kick starter.

Salvation of those demanded right legs was to come in 2002 when Suzuki finally decided to fit an electric starter on the street-legal DR.

By 2003, the water-cooled 398cc single-cylinder, DOHC, four-valved engine developed a decent 40 hp at 7,600 rpm and 39 Nm at 6,600 rpm, so an adventurous rider would have had a hard time passing this chance over. There was also the DRZ400E off-road model which developed significantly more power and torque.

In 2005, Suzuki increased power to 48 hp at 9,000 rpm, together with the introduction of the DR-Z400SM model, while maximum torque was now 41 Nm and it was obtained at higher revs (7,500 rpm). Though the “E” and “S” models were equally powerful, no exterior changes marked the 2005 model years.

Compared to the DR-Z400E, the 2007 DR-Z400S stood out thanks to the on-road legal lighting with bright 60/55 watt halogen headlight, compact tail/stoplight, lightweight, rubber-mounted turn signals and horn. As any proud worthy modern dual-sport motorcycle, the 2007 “S” model featured a compact digital instrument cluster with speedometer, odometer, twin-trip meters with addition/subtraction capability, clock, timer and stopwatch functions. The engine suffered a compression ratio reduction (from 12.1:1 to 11.3:1) in order to make operation on 87-octane fuel possible and that also required the adding of the Mikuni BSR36 CV-type carburetor. Colors were Suzuki Yellow and Blue for 2007.

In 2008, the Yellow was replaced with Black and 2009 brought White instead of Blue.

2010 Suzuki DR-Z400S

Inspired by the Suzuki DR650SE, the subject of today’s review could easily be mistaken with the middleweight all-rounder if there wasn’t for some minor details such as the lack of cooling fins on the engine (as the 400 is liquid-cooled), a smaller silencer and new sharper side plates and graphics.

Though colors available are the same, Black or White, the seat on the DR-Z400S is Gray as well as the graphics, leaving no doubt that Suzuki knows how to set their models apart from one another with great finesse if you ever doubted it.

Like any veritable dual-sport motorcycle, this Suzuki is fitted with spoke wheels (21-inches front and 18-inches rear), a high mounted front fender and a square headlight for that nice 1980s look. The mirrors also feature the square shape, allowing great rear visibility, but that’s pretty much all there is to remind you of that farm motorcycle look.

Press Review

2010 Suzuki DR-Z400S

"On hard terrain, the performance feels the same, but the kick model is stronger in sand and mud and is lighter and cheaper. I don’t feel comfortable pushing the stocker to race pace, but at 85 percent of my race pace the DR-Z eats up the miles without tiring me or beating me up" – dirtrider

"With 31 horsepower and 23 lb-ft of torque, the liquid-cooled mill puts its 90mm bore and 62.6mm stroke to good use. As much as the motor and gearing can dish out, the brakes can give right back. A 250mm disc up front uses a dual-piston caliper for grip and the 220mm out back is pinched by a single-piston." – motorcycle-usa

"The handling is OK, around town, but as the speeds pick up the 21-inch front wheel makes things feel vague and wallowy and the brakes on the Suzuki DR-Z400S are poor. The wide bars let you fling it around and off-road, once the standard tyres are swapped for something more knobbly, it’s quite easy for novices to get to grips with the DR-Z400S." – MCN


Having no competition to say otherwise, the Suzuki DR-Z400S is an economical (65 mpg) and cheap all around motorcycle. I guess you really can’t argue with its $6,099MSRP.


Overall, the Suzuki DR-Z400S may not stand out as refinement itself, but is indeed good at what claims to know doing and things split both ways here: commuting and off-road riding. If you demand both types, then the 400 DR is a highly recommended bike, but if you’re not that much into trail riding, there are more comfortable ways to move around.
