OVERVIEW
Kawasaki’s intermediate KX100 motocross racer
is the logical progression after the kids outgrow
their KX85. Loaded with big KX features, this high
performance racer keep young riders at the front of
the pack.
Boasting a high tensile perimeter frame,
aluminum rims, stiff inverted forks, fully adjustable
suspension, and a new faster revving flywheel, this
KX is a serious competitor.
Sharp graphics include a mono-tone seat cover that
brings the KX100 in line with other 2012 Kawasaki KX
models.
The hi-tech engine features an ignition system with
lighter, stronger neodium magnets for potent spark
at all engine speeds. Modifications to the KIPS and
cylinder porting improve power across the rev range.

KEY FEATURES
Engine
• Quick revving, liquid cooled KX100 engines share many parts
with other KX machines including the crankshaft, transmission,
and intake system.
• Light magneto rotor uses powerful neodium (rare-earth) magnets to
lower inertial moment from 6.3 kg.cm2 to 4.0 kg.cm2 which improves
low-rpm response.
• The KX100 achieves its larger displacement and wider
powerband via its 4.0 mm larger bore (KX100: 52.5 mm; KX85:
48.5 mm).
• Tough 6-speed transmission has bushings on 2nd, 3rd, and 4th gears
on the output shaft for increased durability. Fifth and 6th gears on the
transmission input shaft also ride on bushings.
• Kawasaki Integrated Power Valve System (KIPS) varies exhaust
port height for increased horsepower and torque throughout the
rev range.
• The ends of the shift forks are hard-chrome finished for durability.
• Breather on the KIPS cover relieves exhaust pressure for more
precise KIPS valve action contributing to improved high-rpm
and overrun performance.
• Electrofusion coating on the aluminum cylinder provides rapid
heat transfer, superb wear resistance and optimum lubrication
retention for increased performance and durability.
• Keihin PWK28 carburetor features a crescent shaped slide that
enables the needle to sit closer to the intake ports for quick
throttle response.
• Thick base at the clutch housing fingers for increased durability.
• The right hand engine cover provides a separate clutch cover for quick
servicing at the track without removing the water pump.
• Single radiator mounted on the right side keeps the engine cool during
long motos.

• Carbon fibre reeds aid throttle response. The carbon fiber
weave of the reed valves is 45 degrees to the intake tract so that
the reed is more flexible and correspondingly more responsive
at lower rpm.
• The right side of the airbox is cut back to increase airflow and
draw air from behind the number plate as well as below the
seat. (Photo 1)
• Digital Capacitor Discharge Ignition (CDI) precisely controls
timing, no matter how fast the rpm changes.

KEY FEATURES
Chassis
• High Tensile Steel Perimeter Frame combines narrow
dimensions, steep rake angle and high rigidity for quick handling
without sacrificing straight-line ability.
• Bolt on tail section eases repairs and maintenance.
• 36mm inverted cartridge fork provides a progressive ride to
better resist bottoming and fit larger and more aggressive
riders.

(Photo 3)
• Inverted forks are more rigid to provide better steering response
and control.
• Fork compression damping is 18-position adjustable and the
cartridge design means better action.
• The aluminum
upper fork tubes
measure 49.5mm in
diameter for flex free
performance. (Photo 2)
• Uni-Trak rear suspension
settings provide a
progressive ride to better
resist bottoming and
accommodate larger,
more aggressive riders.

• Fully adjustable rear
shock spring preload,
4-position compression
damping, and 16-position
rebound damping
allows the suspension
to be tuned for specific
conditions.
• Mono-tone seat cover
uses a high-grip top and smooth sides for good grip when sitting and
high mobility when riding on the pegs.
• Hydraulic front and rear disc brakes feature drilled discs for light weight.
