Key Features
Suzuki's industry-leading DualSport
model that combines the best on and off-road features
in a lightweight package.
Basic Differences from DR-Z400E
Compact digital instrument cluster
with speedometer, odometer, twin-trip meters with
addition/subtraction capability, clock, timer and
stopwatch functions.
Smooth throttle response with a MikuniT
BSR36 CV-type carburetor fed by 6-liter airbox.
The left side cover has quick-release fasteners
for easy access to the air filter.
Reduced compression ratio (12.2:1
to 11.3:1) for operation with 87-octane fuel On-road
legal lighting with bright 60/55 watt halogen headlight,
compact tail/stoplight, lightweight, rubber-mounted
turn signals and horn.
Thermostatically-controlled cooling
fan mounted to the left radiator helps maintain
consistent operating temperature in traffic.
Dual-sport tyres to meet highway use
regulations (F: 80/100-21, R: 120/90-18)
Engine Features Shared with DR-Z400E
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
28º 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% 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
