2012 Yamaha Grizzly 450 Auto 4×4 EPS Highlights:
Key selling points:
Grizzly 450 Automatic 4×4 EPS has many of the same
great features as big brothers Grizzly 700 and 550,
including electric power steering, four-wheel
independent suspension, and powered by a
fuel-efficient, liquid-cooled engine.
Steel Blue model includes cast aluminum wheels.
Electric Power Steering system lightens steering for
superior comfort and terrainability.
Almost 10 pounds lighter than previous Grizzly 450
models, even with the addition of Electric Power
Steering, providing awesome power-to-weight ratio.
Industry-exclusive, fully automatic Ultramatic®
transmission is the most advanced drive system in
ATVs. An automatic centrifugal clutch maintains
constant belt tension for reduced belt wear and uses
a sprag clutch for all-wheel downhill engine braking
in 4WD mode.
Three-position On-Command® In/Out 4WD feature
lets you switch between 2WD, limited-slip 4WD and
a fully locked differential 4WD-all with the simple
push of a button. Override button allows engine to
make maximum rpm in full Diff. Lock mode.
Fully independent long-travel four-wheel suspension
features double-wishbone suspension front and rear.
Ground clearance of 10.8 and a high-impact
plastic skidplate provide terrainability and
Trick digital instrument panel boasts a
multifunction LCD display with speedometer,
odometer, dual tripmeter, hour meter, 4WD status,
transmission position and clock.
Rear wet brake is a multi-disc system running in
hydraulic fluid inside a sealed unit. This keeps out
the elements (such as mud and water) while
providing powerful, consistent stopping power and
greatly reduced maintenance.
