Introduction
The Next Step for Future Champions
With an impressive power-to-weight ratio and a compact, nimble
chassis, it's no wonder that the KX™85 is the bike of choice
for riders getting serious about motocross competition. The 85cc
class has long been the proving ground for many of the top riders,
and the KX85 has helped them gain mastery of the track.
This little rocket ship is powered by a two-stroke, 84cc engine
that puts out eye-popping power. Among its race-proven features
are an advanced chassis package with a 36mm cartridge fork that
has 18-way compression damping adjustability and settings designed
to tame the nastiest, most challenging tracks. The UNI-TRAK®
shock in back features fully adjustable spring preload, compression
and rebound damping for superior rear wheel control.
Surrounding all that suspension goodness is a black-painted,
high-tensile steel perimeter frame with a specially designed
fuel tank sitting inside the cage to keep the fuel load and,
thusly, the center of mass as low as possible for improved handling.
All this is wrapped in lime green body panels, with lightweight
black aluminum wheels and aggressive graphics. The result is
a factory-look racer with factory-like performance.
The engine bay features some factory-like tricks of its own,
including an electrofusion-coated cylinder with a narrow squish
band, a large-volume combustion chamber to boost top-end power,
and a 28mm Keihin carburetor featuring a crescent-shaped slide
that positions the needle closer to the intake ports, optimizing
fuel atomization and delivering smoother fuel delivery throughout
the powerband. Further enhancing the KX85's tractable power are
the Kawasaki Integrated Power-valve System (KIPS®) and tuned
exhaust pipe that provides better drive out of corners and a
linear power delivery for young riders of varying skill levels.
The KX85's six-speed transmission delivers smooth and positive
shifting along with enhanced durability thanks to hard chrome-finished
shift fork ends, a thick base on the clutch basket housing and
an additional bushing on the input shaft.
Those who race their KX85 at designated events are eligible to
receive support from Team Green™, Kawasaki's amateur racing
support program. Each year, Team Green provides regional support
vehicles and highly trained technicians at more than 100 events
throughout the United States, offering technical information
and assistance to those who race Kawasaki products. Kawasaki
also offers a comprehensive contingency program for amateur and
professional riders who place well at designated events.
Authentic Kawasaki Accessories are available through Arizona
