MID-SIZE FUEL INJECTED ENGINE
The Grizzly 550 is powered by a fuel injected 558 cc 4-stroke engine, making it one of the most powerful middleweight ATVs on the market. It is fuel injected for easy starting and crisp throttle response, and will automatically compensate for temperature and elevation changes.

EXCELLENT POWER TO WEIGHT RATIO
Power is nothing if it comes with a bunch of additional weight. Considering the Grizzly 550 is lighter than many of the competitors in this class and this bear's power to weight ratio offers some hefty advantages over some of the bigger and bulkier ATVs. Less weight has an effect on everything from handling and acceleration to hill climbing and mud prowess.

ULTRAMATIC TRANSMISSION
Revolutionary Ultramatic™ fully automatic transmission is the first automatic transmission to feature true engine braking. All four wheels receive engine braking in 4WD mode. Dual-range transmission with reverse. Low range has approximately 1.5 times the pulling power of high range.

ON-COMMAND 4WD
Push-button servo-controlled "On-Command" system allows you to switch between 2WD, limited-slip 4WD and fully locked differential 4WD - all with the simple push of a dash mounted button. Real 4-wheel drive when you need it. With Diff-lock engaged, there's no need to wait for one wheel to spin. You have traction to all 4 wheels, immediately. This puts you in total control... you decide when you need 4 wheel drive... the machine doesn't decide for you.

4-WHEEL DISC BRAKES
Slowing your big-bore ATV down shouldn't involve standing on the brake pedal while squeezing the lever with all your might. 4-wheel disc brakes combined with full-time engine braking means slowing this Grizzly down requires less effort. And since the front and rear brakes can be operated independently, you have more control over how you brake depending on the situation.

MASS CENTRALIZATION AND LOWER CENTER OF GRAVITY
A full tank of fuel carries a lot of weight with it. So we located the tank under the seat and the airbox up high where the tank used to be. This lowers the center of gravity which improves handling, stability and hill climbing capability. But it also raises the airbox reducing the chance of water and debris from getting into the engine.

V-BELT DUCTING
High mounted airbox, V-belt intake and exhaust ducts, reduce the opportunity for water and debris to enter the V-Belt housing.

REVERSE MOUNTED REAR SUSPENSION
The wheel center does not change but allows for a shorter frame which improves approach/departure angles, and allows the use of stronger ball joints (more clearance)
