Key Features:

” 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.
” 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 ATV-ing. An automatic centrifugal clutch maintains constant belt tension for reduced belt wear and sprag clutch for all-wheel downhill engine braking in 4WD mode.
” Steel Blue model includes cast aluminum wheels.
” 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 undercarriage protection.
” 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.

” 421cc liquid-cooled, SOHC four-stroke single is rugged and powerful.
” Electric Power Steering system lightens steering for superior comfort and less rider fatigue.

” Large-capacity aluminum radiator provides maximum cooling efficiency and is positioned high in frame for optimal protection.
” Compact engine design features a 45-degree cylinder angle for maximum ground clearance and lower seat height for quick, responsive steering and agility.
” Gear-driven crankshaft balancer and rubber-damper engine mounts reduce vibration.
” Specially designed drive system air intake vent helps prevent overheating and keeps water and mud from entering drive case.
” Tool-free air filter box for easy access and quick maintenance.

” Lightweight chassis features outstanding durability with superior rigidity for class-leading agility and handling.
” Light steering and a class-leading turning radius combine for increased comfort and incredible maneuverability-even in 4WD.
” Fully independent four-wheel suspension features a double-wishbone suspension front and rear delivering 6.3 inches and 7.1 inches of travel.
” Using a newly-designed multi-disc system running in gear oil, the sealed rear wet brake combines strong, consistent stopping power and greatly reduced maintenance requirements.
” Large-diameter ventilated hydraulic front disc brakes deliver tremendous stopping power in a variety of conditions.
” Direct front shaft drive eliminates U-joint for greater durability and more efficient power transfer when engaged in 4WD.
