2021 Suzuki DR-Z 400SM Base $7,499.00

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.

 

Key Features

• 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 MX-style suspension plus high-grip sportbike tires on strong spoke wheels featuring anodized, aluminum Excel rims.
• Solid Black or Solid Special White No. 2 bodywork with new, angular graphics complement the motorcycle's styling.

Engine Features

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

• 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.
• Fed by a six-liter air box, the Mikuni™ 36mm carburetor incorporates a deceleration enricher circuit to help 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 use 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-alloy clutch, magneto, and cylinder head covers contribute to the bike's low weight.

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

• 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 a special 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, and special designed mirrors that rotate, help protect against damage in the case of a tip-over.
