Key
Suzuki’s industry-leading DualSport model that combines the best on and off-road features in a lightweight package
Engine
Smooth throttle response with a Mikuni™ BSR36 CV-type carburetor fed by 6-liter airbox. 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
398cc, DOHC, liquid-cooled, dry-sump engine produces strong low-rpm power
Electric start with lightweight starter motor and a compact 6.5 amp maintenance-free battery
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
Automatic decompression system for quick/easy engine starts
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
Compact 5-speed transmission utilizes a cable-operated clutch with separate outer cover for simplified clutch maintenance
Additional weight savings with magnesium valve cover, clutch cover, and magneto cover
