Despite the fact that it comes with a relatively small engine, the Yamaha Grizzly 450 has the same tough character as its bigger siblings.

At the heart of the ATV lies a 421cc, 4-stroke, liquid-cooled single, SOHC engine paired with Yamaha’s fully automatic Ultramatic transmission. It is also worthy of being mentioned that the transmission features a sprag clutch for all-wheel downhill engine braking in 4WD mode and reverse.

In its off road adventures the ATV is helped by a generous ground clearance (10.8 inches) and a fully independent long-travel four-wheel suspension with front and rear double-wishbones. You also get a tough plastic skidplate for protection.

The rider is met by a modern digital instrument panel which features a speedometer, odometer, dual tripmeter, hour meter, 4WD status, transmission position and clock.

The Yamaha Grizzly 450 Auto 4x4 is offered with a starting price of $7,249.

  • 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.
  • 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 and reverse.
  • 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 composite 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 gear oil inside a sealed unit. This keeps out the elements (such as mud and water) while providing powerful, consistent stopping power and greatly reduced maintenance.
