Hard Hitting Fuel Injected Power
Fuel-injected 449 cc liquid-cooled,
4-stroke Single delivers
hard-hitting powerfrom low- through
high-rpm. The broad powerband and
responsive throttle offer a broad
spread of torquey response that
enables racers to get on the gas and
go even from down low. In addition
to the inherent benefits, fuel
injection contributes to the
KX450F’s lag-free acceleration,
especially after landing jumps.
New Bridge-Box Bottom Piston
New piston, featuring the same
design used on our factory racers,
offers improved performance at all
rpm. A revised profile with a
shorter skirt, reinforced external
ribs and the first mass-production
use of a bridged-box bottom,
featuring fully flush internal
bracing, results in a lighter,
stronger piston.
New Balance Factor Crankshaft
Wedge-shaped crank web increases
offsetting moment for high
crankshaft balance factor. At close
to 60%, the balance factor of the
’10 KX450F is on par with Ryan
Villopoto’s factory racer.
Factory Style Chassis Components
and Tuning
The KX450F’s slim aluminium
perimeter frame is a lightweight
construction composed of forged,
extruded and cast parts. Chassis
balance and settings were all set to
suit race-experienced riders. The
centre of gravity and key dimensions
(swingarm pivot, output sprocket and
rear axle locations) were chosen so
that the rear tyre would drive the
bike forward (instead of causing it
to squat).
Race-Oriented Suspension
Kayaba AOS (Air-Oil-Separate) fork
keeps oil and air in separate
chambers for stable damping
performance during long motos.
Low-friction fork seals contribute
to smooth action.
