2017 Suzuki DR-Z400SM

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 glide 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 difference between the DR-Z400SM and the DR-Z400S are the inverted front fork, wide, spoke-style wheels, and 300mm diameter front brake disc. 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.

ENGINE

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

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

Simple electric starting via a lightweight starter motor with an automatic mechanical decompression system

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 percent lighter than a cast piston and receives additional oil-cooling to the piston crown through a crankcase oil jet

Smooth throttle response with a Mikuni™ 36mm carburetor fed by 6-liter air box. The left side cover has quick-release fasteners for easy access to the air filter

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

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

TRANSMISSION

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

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

CHASSIS

Wide, blue-anodized RK Excel aluminum rims with stainless steel spokes are fitted with high-grip sportbike radial tires: 120/70-R17 front & 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 Supermoto 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 contributes to the trim rear fender appearance

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