2010 Kawasaki KLX125 and D-Tracker
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 Super Moto 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 in stature make them easy for
learners. This high accessibility is enhanced by hassle-free
starting care of electric start and high quality
The KLX125 and D-TRACKER 125, are both
designed to be enjoyable even for highly experienced
riders, offering a level of fun that belies their
size. 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. Like many other top quality Kawasaki’s,
they both feature petal disc brakes offering superb
stopping power along with efficient disc cooling.
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,
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.
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 learn on. Both
bikes also offer tight turning radii.
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
Simple to maintain and durable
- Air-cooled SOHC 2-valve 125cc 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
- Oxygen sensor and muffler catalyser ensure emissions
- 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.
Big-bike style Fuel Injection 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
The FI ECU makes use of input from an intake air
pressure sensor, crankshaft sensor, Oxygen 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.
The combination of an electric starter and fuel
injection ensures hassle-free starting. Starter and
engine stop switch are located on the right handle
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
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
Durable fork guards on the D-TRACKER 125 protect
the fork inner tubes from rocks and debris.
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 petal disc is gripped by
a twin-piston caliper.
The rear wheel is slowed by a 190 mm petal disc
and single-piston caliper.
Whether dressed in a dual purpose or super moto
styling, both the KLX125 and D-TRACKER offer sharp
looks complemented by ideal proportions. Well-balanced
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.
While most bodywork components for the two models
share the same design, the KLX125 and D-TRACKER 125
feature their own unique mirrors and front fenders.
They can be further distinguished by their front forks
35W headlamp uses a quartz halogen bulb and multi-reflector
lens, allowing a compact design. The headlamp is powered
by the battery.
Compact tail light contributes to the stylish appearance
of the rear.
Fully digital instrument panel includes digital
speedometer, bar-type tachometer, clock, odometer,
meter and FI and low fuel warning lamps.
