| Engine: |
- This 558cc 4-stroke SOHC 4-valve liquid-cooled engine is derived directly from the industry-leading Grizzly 700 powerplant.
- Compact engine design features a 35-degree cylinder angle for ground clearance and lower seat height for quick steering and maneuverability.
- Ceramic-composite cylinder liner provides outstanding durability and heat dissipation; 92mm forged piston is light and strong and rides on a carburized chrome-moly connecting rod.
- Two-lobe overhead cam and a pair of needle-roller rocker arms reduce friction by 50 percent for increased fuel efficiency and torque.
- Gear-driven crankshaft balancer shaft and 4-position rubber engine mounts reduce vibration.
- Yamaha Fuel Injection uses a Mikuni® 40mm throttle body and idle speed control valve to provide easy cold starts and flawless fuel delivery in nearly any condition, from below sea level to 15,000 feet.
- Pushbutton electric start with seven-disc torque-limiting damper assembly to protect the starter motor.
- Straight driveshaft layout eliminates U-joints for reduced friction, noise, vibration, and maintenance.
- Stainless steel exhaust system features aluminum heat shields and a screen-type spark arrestor for great power with minimum noise output.
- High-capacity aluminum radiator with fan motor delivers maximum cooling efficiency and is positioned high in the frame for optimal protection.
- 5-position shift lever with L, H, N, R and P gates has a light shifting feel with easy engagement, providing positive Ultramatic® transmission control.
- Override button allows engine to make maximum rpm in full Diff. Lock mode.
- Electronic servo-activated 2WD/4WD/Diff. Lock via the On-Command® system.
- Sealed drive case keeps out water and debris to help increase durability.

| Chassis/Suspension: |
- Electric Power Steering. This assist feature, pioneered by Yamaha on the Grizzly 700 FI EPS, lightens steering for superior comfort and terrainability.
- 5.3-gallon fuel tank is located under the seat for excellent mass centralization and handling; there’s a 4.8-liter waterproof storage compartment under there, too.
- 11.8 inches of ground clearance and full-length composite skidplate deliver maximum underbelly protection while enhancing terrainability.
- 25x8-12 front and 25x10-12 rear Dunlop® tires provide responsive steering and handling and excellent comfort.
- Rugged injection-molded front bumper and CV joint guards protect against rock and debris damage.
- Full-size chassis provides the same high level of comfort enjoyed by Grizzly 700 riders.
- Five-way preload-adjustable shocks provide a comfortable ride, whatever the load or trail conditions.
- Front and rear lower A-arm guards offer excellent protection —and Grizzly 550 features WideArc™ front A-arms for outstanding ground clearance that’s 5 inches wider than that provided by ordinary designs.
- Four-wheel hydraulic disc brakes serve up consistent, long-lasting braking power.
- Direct driveshaft design efficiently transfers power while providing outstanding durability with less vibration.
