OVERVIEW
NEW 125cc DUAL PURPOSE AND SUPER MOTO
MODELS
Kawasaki proudly introduces the new KLX125 and D-TRACKER 125, two brand new
models, whose superb balance, perfect proportions and compact size make them ideal for
new riders.
Both the dual purpose KLX125 (KLX125C) and motard-style D-TRACKER 125
(KLX125D) feature a simple and reliable 125cc air-cooled Single engine mounted in a
lightweight, compact chassis designed specifically for the 125cc class. With low seat
heights and slim seat designs that facilitate planting both feet firmly on the ground, the
bikes are both easy to ride and diminutive statures also make them easy to learn on. This
high accessibility is enhanced by hassle-free starting care of electric start and fuel
injection.
The KLX125 and D-TRACKER 125, both designed to be enjoyable even for highly
experienced riders, offer a level of fun that belies their small size. Highly rigid perimeter
frames are mated to highly capable suspension – including, in the case of the
D-TRACKER 125, an inverted front fork more commonly found on larger bikes. The
engines feature big-bike style fuel injection systems (with individual fuel pump and injector
components) and throttle bodies are equipped with idle speed control. And petal disc
brakes offer superb stopping power along with efficient disc cooling.

OVERVIEW
With chassis components designed exclusively for the 125cc class (rather than borrowed
from larger models), the KLX125 and D-TRACKER 125 have extremely well-balanced
proportions that complement their sharp, modern styling. Wheel size is smaller than that
of rivals (19”/16” for the KLX125; 14” front and rear for the D-TRACKER 125), contributing
to compact proportions and adding to a unique ride feel. Compact headlamp and full
digital instrumentation complete the packages.
KLX125 and D-TRACKER 125 – two great choices for those new to riding, or those who
simply prefer the compact size and light weight that a full-size model cannot provide.

KEY FEATURES
HIGHLY ACCESSIBLE
Lightweight and compact, with low seat heights, simple and reliable engines and
hassle-free starting, the KLX125 and D-TRACKER 125 offer highly accessible,
non-intimidating packages, making them ideal for new riders.
Lightweight & compact
* Because their chassis components were designed specifically for the 125cc class,
the KLX125 and D-TRACKER 125 offer lightweight, compact packages.
* The combination of light weight and small size make both machines easy to ride
and easy to walk alongside. Both bikes also offer tight turning radii.
* Curb mass is as follows.
- KLX125: 113 kg
- D-TRACKER 125: 114 kg
* Compact 7.0 litre fuel tank contributes
to low overall machine weight and
minimises weight above the centre of
gravity.
Low seat height
* The compact packages also result in low seat heights.
- KLX125: 830 mm
- D-TRACKER 125: 805 mm
* Slim seat design complements the
low seat height, making it even easier
for riders to reach the ground with
their feet.
Simple engine
* Air-cooled SOHC 2-valve 125 cm3 Single has an output of 10 PS.
* 27.5 mm intake valve and 24 mm exhaust valve have an included angle of 58˚.
* Valve actuation is via rocker arms with valve clearance adjusters.
* Oxygen sensor and muffler catalyser ensure emissions are clean.
* 5-speed manual transmission offers a gear for every situation.
* 5-plate clutch uses three different types of friction plates to ensure durability while
reducing clutch noise.

KEY FEATURES
Big-bike FI system
* Instead of a discharge pump type FI system, the KLX125 and D-TRACKER 125
feature a big-bike style FI system (where fuel pump, injector and throttle body are all
separate pieces). This type of system reduces the chance of air ingestion, making it
ideal for spirited sports riding.
* Throttle body is equipped with ISC (Idle Speed Control) to ensure stable idling when
starting a cold engine, riding at high altitudes, or restarting a hot engine. Engine
speed is adjusted automatically, so riders do not need to. This is the first use of ISC
on a Kawasaki motorcycle.
* The FI ECU makes use of input from an intake air pressure sensor, crankshaft
sensor, O2 sensor, neutral switch, vehicle-down sensor, throttle position sensor,
engine temperature sensor and intake air temperature sensor to control the fuel
injector, fuel pump, ignition coil and ISC valve.
* The tank-mounted fuel pump
incorporates a fuel level sensor.
When the fuel level becomes low, a
low-fuel warning lamp will come on.
Hassle-free starting
* The combination of an electric starter and fuel injection ensures hassle-free starting.

KEY FEATURES
* Starter and kill switch are located on
the right handle grip.

KEY FEATURES
BIG FUN IN SMALL PACKAGES
Despite their small size and simple construction, the KLX125 and D-TRACKER 125 were
designed to be Fun Bikes that even pro riders could enjoy.
Highly rigid perimeter frame purpose-built for the 125cc class
* The all-new steel perimeter frame was custom-built for the 125cc class. Its high
rigidity, compact size and light weight offer excellent handling qualities and
contribute to easy manoeuvrability.
* A combination of form and function, the frame was also designed to be easy to grip
with the legs, offering superior chassis control to the rider.
Highly capable suspension
* Combined with the highly rigid frame, highly capable suspension ensures excellent
handling and feedback. Like all the other chassis components, the front and rear
suspension were designed specifically for the 125cc class.
* The KLX125 features a 33 mm telescopic fork. Its 175 mm stroke is ideal for a dual
purpose machine, able to handle both on- and off-road conditions.
* The D-TRACKER 125 is equipped with a 35 mm inverted fork. With the spring in the
left tube and damping force provided by the right tube, the fork offers both
performance and light weight. The fork’s settings and 150 mm stroke are ideal for
road and motard-use.
* Durable fork guards on the D-TRACKER 125 protect the fork inner tubes from rocks
and debris.
2010MY D-TRACKER 125 MODEL INFORMATION PAGE 8

KEY FEATURES
* Both models use a single shock
absorber with pressurised nitrogen
gas at the rear.
Small wheels and tyres
* Selected as best match for the 125cc class-specific chassis, small rim and tyre
sizes contribute to the compact package and enhance manoeuvrability.
* The KLX125 features a 19” front wheel and 16” rear. Tyres are as follows:
- F: 70/100-19M/C 42P
- R: 90/100-16M/C 51P
* The D-TRACKER 125 features 14” wheels front and rear. Tyres are as follows:
- F: 100/80-14M/C 48P
- R: 120/80-14M/C 58P
* In both cases, the small tyres sizes are Kawasaki’s first use on a street model.
Petal disc brakes
* Petal brake discs front and rear provide superb stopping power. In addition to
helping reduce unsprung weight, the wave shapes of the petal discs help clean the
brake pads for more efficient braking performance.
* At the front, a 240 mm disc is gripped
by a twin-piston caliper.
* The rear wheel is slowed by a 190 mm disc and single-piston caliper.

KEY FEATURES
* Thickness for both petal discs is 3.5
mm.

KEY FEATURES
SHARP LOOKS
Whether dressed in a dual purpose or motard styling, both the KLX125 and D-TRACKER
offer sharp looks complemented by ideal proportions.
Well-balanced proportions
* With all chassis components were designed specifically for the 125cc class (rather
than borrowed from larger-displacement models), the KLX125 and D-TRACKER
125 have very well-balanced proportions that add to their sharp appearance.
Modern styling
* While most bodywork components for the two models share the same design, the
KLX125 and D-TRACKER 125 feature their own mirrors and front fenders. They can
be further distinguished by their fork and wheels.
* 35 W headlamp uses a quartz
halogen bulb and multi-reflector lens,
allowing a compact design. The
headlamp is powered by the battery.
2010MY D-TRACKER 125 MODEL INFORMATION PAGE 11

KEY FEATURES
* Compact tail light contributes to the
stylish appearance of the rear.
Digital instrumentation
* Fully digital instrument panel includes
digital speedometer, bar-type
tachometer, clock, odometer, trip
meter and FI and low fuel warning
lamps.
