Grizzlys don't come any tougher than this

Tackles tough terrain and even tougher chores with a host of Yamaha exclusive features including fully automatic Ultramatic transmission, On Command 2WD/4WD with Diff Lock, rear sealed wet brake and more, all in the great handling package.

Key Features

• Grizzly 450 Automatic 4x4 has many of the same great features as big brothers Grizzly 700 and 550, including four-wheel independent suspension, and it's powered by a fuel-efficient, liquid-cooled engine.

• 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 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 inches 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.

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

• Pushbutton electric starting.

• Stainless steel muffler and header design provides superior power characteristics, exhaust sound and durability.

• Left-side–mounted (Hi/Lo/N/R/P) shift lever is easily accessible.

• 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.

• Heavy-duty composite front carry bar and CV joint guards help prevent damage to boot covers and won't dent or rust.
