A perfect blend of comfort, capability and ruggedness with a new rear sealed wet brake.

” Almost 20 pounds lighter than previous Grizzly 450 models, providing awesome power-to-weight ratio.
” Industry-exclusive, fully automatic Ultramatic® transmission is the most advanced drive system in ATVing. An automatic centrifugal clutch maintains constant belt tension for reduced belt wear and 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.

” 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.

” Semi-oval slide 33mm BSR Mikuni® carburetor and high-output DC-CDI ignition deliver fantastic throttle response and engine performance at all rpm.

” 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.

” 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.
