| Key Features: |

- 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.
