Compact digital instrument cluster with speedometer, odometer, twin-trip meters with addition/subtraction capability, clock, timer and stopwatch functions

Smooth throttle response with a Mikuni™ BSR36 CV-type carburetor fed by 6-liter airbox. The left side cover has quick-release fasteners for easy access to the air filter

Reduced compression ratio (12.2:1 to 11.3:1) for operation with 87-octane fuel

On-road legal lighting with bright 60/55 watt halogen headlight, compact tail/stoplight, lightweight, rubber-mounted turn signals and horn

Review

Brilliantly competent dual-purpose motorcycle that’s as happy pottering through the gridlock as it is bouncing over a paddock. The DR-Z400S is tough, durable, simple to service and spares are cheap and plentiful. The Suzuki DR-Z’400S' bit heavy for true off-roading but greenlaners love it for its indefatigable charm.

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.

The Suzuki DR-Z400S' SOHC single is in a low state of tune, so it’s easy for beginners to get on and use. It’s reliable and easy to service at home. There’s enough oomph to lift the front wheel over obstacles and the low down shove makes traffic duties a cinch on the Suzuki DR-Z400S. Doesn’t do motorway speeds with enthusiasm.

Build quality is fair, but the frame paint is easily rubbed off and the cases look tatty quickly on the Suzuki DR-Z400S. The plastics are rugged and cheap to replace. Reliability on the whole is excellent and the DR-Z400S makes a pretty fair case for itself as an unburstable, unbreakable tool.
