It features a compact 4-valve cylinder head with 36mm intake valves, 29mm exhaust valves, narrow 28-degree included valve angle and shim-under-bucket valve adjustment system. This lightweight 398cc liquid-cooled engine produces strong, tractable low-rpm power. The DR-Z400SM has a forged aluminum piston which is 10 percent lighter than a cast piston and receives additional oil-cooling to the piston crown through a crankcase oil jet. The transmission is a compact 5-speed cable-operated clutch. Unlike most dual sport bikes it features long travel (Showa) inverted front forks.

History
First introduced in 2005, the Yellow painted Suzuki DR-Z400SM was derived from the “S” sibling so it featured the same engine, gearbox and frame, but introduced a whole new kind of excitement to the amateurs of street, track and soft off-road riding. The numbers behind it were 34.65 hp at 7,750rpm and 25.91 lb-ft at 6,000rpm so there was plenty to rely on in whatever riding situation.
In 2006, they added Black as a shiny new color available and white-colored turn signal lenses for improved appearance, but, apart from that, the SM was pretty much the same.
The 2007 model year would have not featured any color changes, not to mention mechanical ones as the bike was still relatively new on the scene. Yet, they added Renthal tapered aluminum handlebars in order to reduce the vibrations coming from that single-cylinder engine and added a more aggressive look to a fairly sporty model. Also, this is where the new front and rear axle sliders were added.
The last notable change came in 2008 from the design department. The new White color scheme replaced the now old Suzuki Yellow that was more of a motorcross bike characteristic.
Though a typical supermoto bike, the 2010 Suzuki DR-Z400SM brings its own special share of design features on the “highly competitive” market. The bike’s off-road roots still count a lot as they prove SM’s muscle in no matter what environment you choose to ride it. The square headlight is in for road-legality, but together with the high-mounted fenders, mudguards, number and side plates are all testimony of this bike’s abilities to go off-road. The wide, spoked 17-inch wheels with grippy tires attribute street performance to it, but the balance tends to incline more on the off-road side at least in what concerns design.
2010 doesn’t bring new color schemes, just new decals to mark the pass. These are very discrete when covering the side plates of the Black SM and more lively in the case of the White coloring.
