Suzuki DR-Z 400SM

Suzuki’s SuperMoto DR-Z400SM is based on the proven DR-Z400S. So it combines Supermotard style and features in a narrow, lightweight, street-legal package. This bike brings off-road soul and fun to paved roads. It’s not uncommon to take the SuperMoto down a twisty forest road, around tight canyon corners, or through commuter traffic.

Its 398cc, liquid-cooled, four-stroke engine provides strong low-rpm torque and crisp throttle response for any of these occasions. Key differences between the DR-Z400SM and the DR-Z400S are the inverted front fork, wide, spoke-style wheels, and 300mm diameter floating front brake rotor. The inverted fork contributes to less unsprung weight and improved overall handling, while the large brake and wider rims with high-grip tires offer an exhilarating sportbike experience.

The DR-Z400SM welcomes you to the exhilarating world of supermoto riding with cutting-edge dual-purpose bike design and stylish, functional top-grade equipment that captures the essence of free-spirited street riding pleasure.

Engine

Lightweight, 398cc, DOHC, liquid-cooled, dry-sump engine produces strong, tractable power.

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

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

Forged aluminum piston is 10 percent lighter than a cast piston and receives additional oil-cooling through a crankcase oil jet.

A refined Mikuni 36mm carburetor, with new deceleration enricher circuit, is fed by a six-liter airbox to provide smooth throttle response when accelerating or engine braking.

The left side body cover has quick-release fasteners for easy access to the air filter.

The addition of a PAIR (air supply) system to the exhaust helps the motorcycle achieve emissions compliance without affecting performance.

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

Magnesium valve cover, clutch cover, and magneto cover provide additional weight savings.

Transmission Features

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

Low-maintenance, long-life, sealed O-ring type drive chain produces minimal sounds when riding.

Chassis Features

Wide, blue or gold anodized RK Excel aluminum rims with stainless steel spokes are fitted with sporty radial tires: 120/70-R17 front and 140/70-R17 rear.

Strong braking performance is supplied by a front disc brake with a large 300mm floating-type rotor and dual-piston caliper, plus a 240mm rear disc brake with single-piston caliper.

Long travel, Showa inverted front fork is derived from a RM250 and features adjustable compression/rebound damping and alumite coating on inner tube surfaces for smooth action.

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

Renthal tapered aluminum handlebar has an aggressive look, reduces vibration, and has a great bend for spirited riding.

Chrome-moly steel frame tuned for Supermotard style riding 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 sub-frame helps reduce weight, simplify maintenance, and contribute to the trim rear fender appearance.

Front and rear axle sliders help protect against damage in the case of a tip-over.

Electrical Features

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

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

Electrical systems, including the easy-push button starter, are powered by a compact, 6.5-amp, maintenance-free battery.

Additional Features

12-month limited warranty. Longer coverage periods with other benefits are available through Suzuki Extended Protection (SEP).
