KLX250TBF
MODEL NAME:
KLX250S
ENDURO RACER-BASED DUAL PURPOSE MACHINE
A road-going version of the KLX300R enduro racer, the KLX250S retains a significant amount of character
and performance from its larger brother. Lightweight and compact, its 250cc liquid-cooled DOHC engine,
largely based on the power plant of the 300R, has a wide torque band, pulling from down low and continuing
well into the over-rev.
The lightweight, high-tensile steel perimeter frame offers both great cornering performance and straight-line
stability. And the 43 mm inverted cartridge fork and fully adjustable gas-charged rear shock allows the KLX
to be enjoyed both off-road and on.
ENGINE
249cc Four Stroke Single
HThe KLX250S has the KLX300R
compact liquid-cooled 4-stroke Single engine, with a number of changes
which contribute to its multi-role performance.
HThe 34 mm semi-flat slide CVK carburettor delivers the optimum amount of fuel at all rpm, contributing to
excellent response and power, as well as good fuel economy.
H 4-valve DOHC cylinder head provides maximum valve area for optimum flow. Low reciprocating weight
(thanks to the use of a cam lobe for each valve, with shim-under tappet arrangement) contributes to higher
efficiency at high rpm.
H The KLX250S engine features an electrofusion cylinder. The ultra-hard coating in the aluminium cylinder
bore offers superior heat transfer with light weight. It also contributes to engine reliability: the coating holds
lubrication well, resists abrasion and seizure, and allows a tight piston-cylinder clearance for increased
horsepower.
H A gear-driven engine balancer ensures smooth power delivery from idle to redline.
Electric Start
H With an electric starter and Kawasaki Automatic Compression Release (KACR), which automatically lifts
an exhaust valve at cranking rpm, starting the KLX250S is a breeze.
Close Ratio Transmission
H The gear ratios chosen give the KLX250S a true 6-speed transmission
rather than 6th gear being an overdrive.
H A revised change drum cam shape offers better shift feeling, with gear
shifting being more positive.
Exhaust System
H A pipe catalyser and secondary air system ensure clean emissions.
H The muffler is also equipped with a spark arrester, meaning the
KLX250S can access designated off-road public riding areas.
Compact High Capacity Radiators
H Dual high-capacity Denso radiators like those used on our KX motocross bikes deliver superior cooling
efficiency and contribute to space and weight savings. The radiators are very slim and feature tightly packed
cores and a fin design for excellent heat dispersion. Powering the cooling fan is a thin print motor.
CHASSIS
Frame and chassis components based on those of the KLX300R are the source of the KLX250S’s high-level
of off-road performance.
Frame
H The KLX250S’s box and tubular-section high-tensile steel perimeter frame creates a slim, lightweight
package. The 26.5 degrees caster angle and short wheelbase contribute to quick handling, while the
high rigidity of the frame ensures straight line stability.
Suspension
H The 43 mm inverted cartridge-style front fork comes with 16-way compression damping adjustment. The
cartridge provides consistent damping force by minimising aeration of the fork oil. KX style fork guards
protect the inner tubes from rocks and brush.
H Uni-Trak rear suspension provides great road holding ability and bump absorption.
The gas-charged shock with remote reservoir has 16-way compression and rebound damping and fully
adjustable pre-load.
Swingarm
H The lightweight, highly rigid aluminium D-section swingarm contributes to reduced unsprung weight.
H KX racing-type chain adjusters allow precise adjustment of chain slack, helping to minimise drive train
power transfer loss.
Wheels/Tyres
H Wheel rigidity care of thick spokes (4.0 mm) contributes to light, smooth
handling and offers greater
durability for off-road riding.
H Tyres feature smaller blocks for longer tyre life and increased grip on asphalt.
KX Style Petal Discs
H Front and rear disc brakes offer impressive stopping performance.
H A twin piston caliper grips a 250 mm disc up front. At the rear, a single-piston caliper
operates a larger
240 mm rear disc.
Ergonomics
H The relaxed riding position makes the bike easy to ride and control.
H Footpegs are positioned close to the bike’s centre line for a slim riding position
conducive to both on and
off-road riding.
Agressive Styling
H The KLX250S features aggressive styling that is sure to turn heads whether riding in the city or off
the beaten path.
Bodywork
H Front and centre, a new front cowl and headlamp design give the KLX an aggressive image.
H Radiator shrouds are two-piece like those on our KX
motocrossers.
H An off-road style rear fender is a two-piece unit.
H Sharp tail light design offers increased visibility and
further contributes to the KLX’s aggressive new styling.
All-digital Instrumentation
H All-digital instrument console gives at a glance
information.
H Features include a digital bar-graph tachometer, digital
speedometer, clock, and dual trip meters.
