Suzuki DRZ400 S

Key Features

Suzuki's industry-leading DualSport model that combines the best on and off-road features in a lightweight package.

Basic Differences from DR-Z400E

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

Smooth throttle response with a MikuniT 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.

Thermostatically-controlled cooling fan mounted to the left radiator helps maintain consistent operating temperature in traffic.

Dual-sport tyres to meet highway use regulations (F: 80/100-21, R: 120/90-18)

Engine Features Shared with DR-Z400E

398cc, DOHC, liquid-cooled, dry-sump engine produces strong low-rpm power Electric start with lightweight starter motor and a compact 6.5 amp maintenance-free battery.

Compact 4-valve cylinder head with 36mm intake valves, 29mm exhaust valves, narrow 28 included valve angle and shim-under-bucket valve adjustment system.

Automatic decompression system for quick/easy engine starts.

SCEM-plated cylinder (nickel-silicon-phosphorous) is lighter and more durable than an iron liner with excellent heat transfer properties.

Forged aluminum piston is 10% lighter than a cast piston and receives additional oil-cooling to the piston crown through a crankcase oil jet.

Compact 5-speed transmission utilizes a cable-operated clutch with separate outer cover for simplified clutch maintenance.

Additional weight savings with magnesium valve cover, clutch cover, and magneto cover

Chassis Features Shared with DR-Z400E

Narrow profile with smooth transitions between the tank, seat and bodywork Chrome-moly steel frame is torsionally strong with minimal weight. The backbone tube, front down tube, and steering head gussets form the dry-sump engine oil tank.

A bolt-on aluminum subframe helps reduce weight and simplify maintenance.

Long travel, 49mm cartridge-style forks feature adjustable compression/rebound damping and adjustable spring preload for all types of on/off-road terrain.

A fully-adjustable rear shock absorber with high/low speed compression damping adjuster and aluminum swingarm for precise rear wheel control.

Sure stopping power is supplied by a 250mm front disc brake with dual-piston caliper, and a 220mm rear disc brake with a single-piston caliper.

Chrome-moly steel footpegs, aluminum rims/hubs, plus engine guard and rear disc guard.
