Smooth power
Smooth power at your command. The
DR125SM’s air-cooled, 4-stroke 124cm3 engine
design makes use of advanced technology and
well-proven features to deliver responsive
power along with superb economy and
durability for years of enjoyable ownership.
The compact, lightweight powerplant uses
aluminum-alloy cylinder head, head cover
and cylinder (with cast-iron sleeve); highly
efficient flat-type piston and pentroof
combustion chamber; and silent-type cam
chain and automatic cam-chain adjuster.
Conrod big-end needle-roller bearing and
crankshaft ball bearings reduce
mechanical losses. SJCS (Suzuki Jet
Cooling System) jets oil at high speeds
to the piston underside and cylinder
wall for better durability and less oil
consumption. A single-shaft
counterbalancer with damping
mechanism keeps the engine running
smooth for comfortable rides.
Engine power is transmitted with a
well-proven, smooth-shifting 5speed gear box.
Advanced fuel injection and
engine control
A simple, compact and efficient
DCP-FI (Discharge Pump Fuel
Injection) design contributes to
better fuel economy, cleaner
emissions and a user-friendly
power character. Fuel injection
and ignition timing are precisely
controlled by signals from a 10pulse multi-tipped crank sensor
and other sensors. An ISC
(Idling Speed Control)
mechanism adjusts intake airflow volume to maintain proper
idling rpm at all times, and also
performs fast-idling during cold
starts. The clean-running
DR125SM engine meets the
stringent Euro 3 emissions
regulations with a catalyzer and
air/fuel ratio control by the ECM
(Engine Control Module) based
on an exhaust-pipe O2 sensor
feedback.
Functional, stylish electrical designs
The electrifying DR125SM riding
action is supported by an ECM
using a 16-bit ROM
microcomputer. The action
starts easily with an electric
starter. A bright 35/35-watt
high/low beam halogen multireflector headlight shines your
way. A 21/5-watt rear
combination lights help keep
you seen from the rear. The 10watt front and rear turn signals
combining clear outer lens with
amber inner lens are both
stylish and highly visible. The
easy-to-read instrument panel
contains an analog
an odometer and
speedometer, an
tripmeter, and various indicator
lamps, in a distinctly modernlooking layout.

Sporty chassis
The DR125SM chassis offers an
exquisite combination of compact,
user-friendly convenience and the
“supermotard
supermotard” riding
distinctive “supermotard”
feel. The functional front forks and
rear shock fitted on a rigid steelpipe diamond frame each carry
spoked wheels featuring RK Excel
aluminum rims. 17-inch Pirelli tires,
offering a fine balance between
road grip and long wear, are tailored
for agile street maneuvers and the
right supermotard image. Front
250mm- and rear 220mm-disc
brakes, each with a Nissin caliper,
provide ample stopping power.
Convenience features include a
locking tool box and fuel-tank cap,
grab bars for the corider and a
helmet holder. A rear carrier is
optionally available.

Nobody will mistake the DR125SM for anything other than a
“supermotard”-type machine; at the same time, nobody will
mistake the DR125SM for any other supermotard bike. The
distinctive design, composed of wide, expressive surfaces
accentuated with edgy lines, opens a new chapter on
supermotard bodywork styling. The fuel-tank upper
surface is almost completely covered for a classy form.
The tank cover is also extended at the bottom for a
radiator-shroud-like image. Fender covers add
robustness to the front face. The muffler is
purposefully swept up along the frame
cover/rear fender, above which is a sporty,
two-tone flat-shaped off-road-type seat.
Neat bodywork cut-outs and slits on
the tank, frame covers and headlight
- inspired from traditional Japanese
“oni” demon fangs and horns
motifs - add the finishing
touches to the DR125SM’s
strong styling character.
