1991 Kawasaki KX motocrossers
~-------,
The all-new KX80 gets a tubular perimeter frame similar to
the ones introduced on the
KXI25 and 250 last year. Like
its bigger brothers, the 80's fuel
tank dips into the frame for a
lower center of gravity. A single radiator hides behind the
shroud, while the exhaust goes
up the other side. Other chassis
changes include an improved
swingarm, revised-ratio UniTrak linkage and improved
damping in the rear shock.
The engine now has an
electrofusion-coated cylinder
with improved porting and a
five-bolt cylinder head for rigidity. Kawasaki will once again
have the KX60 in its lineup for
the younger riders.
Both the KXI25 and 250
.share the same improvements such as broader
powerbands, microcomputer controlled digital
ignitions, larger-diameter
inverted forks, dual-piston
front disc brake calipers,
lighter wheels, improved
perimeter frames, revised
Uni-Trak suspension linkage attached to more rigid
swingarms, aluminum rear
subframes, recessed chain
adjusters and sintered metal
brake pads. The KX250 gets
a new exhaust pipe to
improve top-end power
as well.
The KX500 still didn't get the
perimeter frame and is relatively unchanged for 1991.
Like the 125 and 250 it gets
larger-diameter inverted cartridge forks , dual-piston front
brake caliper, lighter wheels
and recessed chain adjusters,
plus a recalibrated rear shock.
For the off-readers, the
KDX200 returns to the Kawasaki lineup in 1991 with only
slight graphic changes.
