Suzuki's Supermotard model, based on the proven DR-Z400S, combines Supermotard style and features in a narrow, lightweight, street-legal package
Versatile and strong, 398cc, DOHC, liquid-cooled, dry-sump engine has push-button starting
SuperMoto boasts fully adjustable suspension and strong spoke wheels featuring high-grip sportbike tires on wide aluminum rims
White bodywork with red or blue accent graphics complement the motorcycle’s styling
The white and red DR-Z400SM features bright, gold anodized Excel wheel rims, while the white and blue bike features blue anodized rims that stylishly exude performance
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.
Simple electric starting is powered via a lightweight starter motor with an automatic mechanical decompression 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.
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.
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.
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.
