Engine:

• This 558cc 4-stroke SOHC 4-valve liquid-cooled engine is derived directly from the industry-leading Grizzly 700 powerplant.
• 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.
• The cylinder head has been optimized to deliver excellent throttle response and low-end power, roller-bearing rocker arms to reduce friction for 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.
• 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.
• Five-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 prevent belt from slipping.

Chassis/Suspension:

• Full-size chassis provides the same high level of comfort enjoyed by Grizzly 700 riders.
• 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.
• Five-way preload-adjustable shocks provide a comfortable ride, whatever the load or trail conditions.
• CV boots are made of tough polyethylene for more durability than typical rubber boots.
• Four-wheel hydraulic disc brakes serve up consistent, long-lasting braking power.
• 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.
• 25×8-12 front and 25×10-12 rear Dunlop® tires provide responsive steering and handling and excellent comfort.
• Direct driveshaft design efficiently transfers power while providing outstanding durability with less vibration.
