Very few bikes can combine all the positive qualities of a super moto and a moto cross bike into one exciting package. But of those few, one that stands out is the Suzuki DR-Z400S.

Packed with impressive performance credentials and all-world handling capabilities, the DR-Z400S allows riders to travel on just about any imaginable surface. The powertrain - a 398cc, DOHC, liquid-cooled, dry-sump engine - produces strong low-RPM power while its compact 4-valve cylinder head features large 36mm intake valves and 29mm exhaust valves, helping produce broad, tractable power and torque. Suzuki also added in its own Composite Electrochemical Materials cylinder to provide impressive heat transfer in a lightweight and durable package. There’s also a forged aluminum piston that’s 10 percent lighter than a cast piston and receives additional oil-cooling to the piston crown through a crankcase oil jet.

Besides its impressive performance credentials, the DR-Z400S also comes with a firm and sturdy chassis and suspension set-up that includes a narrow frame that combines thin chrome-moly steel tubes for exceptional torsional rigidity with minimal weight. Meanwhile, the backbone tube, front down tube, and steering head gussets form the dry-sump engine oil tank while a bolt-on aluminum subframe helps reduce weight and simplify maintenance, allowing for an ease-of-use that very few bikes can rival.

The DR-Z also comes with a sturdy aluminum skidplate to protect its underbelly, along with plastic guards that will put up token resistance to defend the water pump and left sidecover. The lights set-up features on-road legal lighting with a bright 60/55 watt H4 halogen headlight and a compact tail/stoplight, as well as lightweight, rubber-mounted turn signals.

Ultimate Motorcycling----"Throughout the years, the Suzuki DRZ400S became more technologically advanced, as can be observed on the latest edition, the 2012 model. Some of the technology instilled in the street and trail Suzuki DR-Z400S are the forged aluminum piston and digitally mapped DC-CDI system that monitors throttle position/engine rpm, just to name a new."

This is something for a motocross. But it looks too aggressive and too big for a thin bike. Anyway, I am sure that this can run fast and win every competition that will come.

This has an impressive engine performance and seems like always ready for action. I love the angst that this motorcycle has. The design is cool especially with that spring, but the wheels are similar with others.
