2021 Suzuki DR-Z400S [Model Overview]

2021 Suzuki DR-Z400SM

Ride the 2021 Suzuki DR-Z400S Anywhere

The DR-Z will be cemented in dual-sport history as one of the greatest motorcycles ever produced for both off and on-road riding. You don’t have to bother with loading your dirtbike into the back of your truck and trailering your toy to the riding destination, because with the DR-Z400S you may as well have just rode there, to begin with.

Suzuki Motorcycles has continued the legend of the DR-Z400S with the use of its bulletproof 398cc, liquid cooled engine that produces up to 39 horsepower and 29 lb-ft of torque. Although the SM version of this Japanese-made dual-sport is slightly more geared towards street use, there are some notable features the DR-Z400S has to make life on the trails a little bit easier.

For this year in the 2021 Suzuki Lineup, the DR-Z400S features adjustable suspension, electric start, and slightly smaller brake rotors than what you would find on the SM variant. Not much has changed from the 2020 model, but you will have new color options for the motorcycle as well as some refinements made here and there.

The 2021 Suzuki DR-Z400SM starts at $6,899 USD / $9,061.04 CAD

2021 Suzuki DR-Z400SM

2021 Suzuki DR-Z400S Features

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.

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.

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

Wide, blue or black 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 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.

Derived from the off-road DR-Z400, the black or white bodywork features new, angular graphics for race-ready appearance.

A pouch on the rear fender carries the tool kit, owner’s manual or other cargo.

Electrical Features

Compact, digital instrument cluster includes speedometer, odometer, 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).

A variety of Genuine Suzuki Accessories for DR-Z400SM owners are available, including a low-profile seat, cargo rack, handguard set, and a large selection of Suzuki logo apparel.
