2010 Yamaha Grizzly 550 FI EPS Camo AP HD

The 2010 Yamaha Grizzly 550 EPS comes fully equipped with a powerful fuel injected 558cc 4-stroke engine, On-Command 4-wheel drive, 4-wheel disc brakes, the fully automatic ULTRAMATIC transmission, and electric power steering. The combination of these key features and Yamaha’s proven durability and reliability, contrinue to make the 2010 Yamaha Grizzly one of the best selling ATVs in Canada.

Following in its bigger sibling’s path, the 550 comes with all the same great features as the famed 700.

All 550 Grizzly’s come standard with powerful fuel injected engines for easy cold starting, superior ground clearance to get you over any terrain, and 4-wheel disc brakes combined with full-time engine braking means slowing the Grizzly down requires less effort. “EPS” versions are available with the latest Electric Power Steering technology for the ultimate in low fatigue ride comfort. Throw in Yamaha’s exclusive Ultramatic® transmission and On-Command drive selection and these Grizzly’s are the ultimate in all terrain vehicles.

“In our annual 550 Shootout, the Grizzly took top honours for ride quality against formidable competition … picking your way over gnarly trails or opening it up on fire roads, this is a superb engine and tranny combo.” – All Terrain Vehicle magazine



Mid-sized 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.


Electric Power Steering

With EPS we’ve been able to dramatically reduce steering effort, especially in 4WD. At the same time, EPS helps isolate you the rider from external forces acting on the front wheels. This means you can worry less about what the terrain looks like, and focus on enjoying the ride. Did we mention it’s speed and torque sensitive? EPS could be the single most important improvement to your off road experience in decades!

reduces steering effort in all situations, helping to reduce rider fatigue while enhancing rider confidence and ease of operation

speed and torque sensitive

improves stability on virtually all types of terrain at a wide range of speeds

helps isolate the rider from external feedback from obstacles that come in contact with the front wheels.


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)


Additional Features

Aluminum cylinder with ceramic composite plating for improved durability

Roller bearing rocker arms for reduced friction and improved engine performance

Forged piston and carburized Chrome-Moly connecting rod for improved durability

Revised intake and exhaust ports

New throttle lever for reduced lever effort

Airbox design has centrifugal debris trap to improve air flow

Flat type foam air filter for easy cleaning

Straight drive shaft layout for reduced vibration and improved durability

Gull-wing front a-arms for improved ground clearance

Polyethylene ball joint boots, front and rear

Air cushion seat to provide comfort on those long rides.

Floor boardwith large holes for mud evacuation, and special rugs to avoid buildup from underneath.

Water resistant storage

Centralize wiring layout, positioned for improved protection against the elements.

LCD Gauge includes Odometer, Trip 1, Trip 2, Clock, Fuel gauge and Gear position

Warning indicators: Engine, Water Temp., Reverse, Neutral, Parking, High Range, Low Range and LCD Drive / Differential Lock map .

35W Halogen headlight bulbs

Neodymium hi-power magnet for improved output, charging capacity and light weight.

Oil fed stator for improved cooling and reliability

Forged Aluminum steering knuckle

Gate type transmission shifter for improved shift feel.

Cartridge type oil filter located to the front of the engine for improved cooling and simplified maintenance
