2011 Yamaha Kodiak 450 4×4 EPS

Need big-ATV capabilities without the big size? Take a look at our versatile 2011 Yamaha Kodiak 450. Designed with the same great features found on our larger Grizzly models, this midsize ATV is more manoeuvrable without sacrificing power and performance.

We engineer our Kodiak 450 every bit as rugged as our Grizzly’s.

And for 2011, this tough mid-size ATV becomes even more manoeuvrable with the addition of Electronic Power Steering. Cradled within the steel frame you’ll find a powerful 421cc, 4-stroke, SOHC, liquid-cooled engine complete with Yamaha’s unbeatable reliability and durability. Pushing power through Yamaha’s exclusive Ultramatic transmission – featuring both high and low range – with true engine braking to give you added control when descending steep hills. At the push of a handle-bar mounted button, you can select between 2WD, 4WD and Diff-Lock 4WD, using the On-Command system to suit the terrain under your wheels. The long-travel suspension 10.8 inches of ground clearance and high-traction tires round out the characteristics of this midsized ATV.

Key Features:

Excellent Power to Weight Ratio

Power is nothing if it comes with a bunch of additional weight. Even with the addition of EPS, Yamaha’s 2011 Kodiak 450 is almost 10 lbs lighter than the ’09 Kodiak 450 making it one of the lightest in its class. With this improved power to weight ratio comes a hefty advantage over some of the bigger and bulkier ATVs. Less weight has an effect on everything from handling and acceleration to hill climbing.

Electronic Power Steering

The introduction of EPS dramatically reduces steering effort, especially in 4WD. It also helps isolate the rider from external forces acting on the front wheels, which means you can worry less about the terrain and focus more on enjoying the ride. This speed and torque sensitive EPS system 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
* Variable assist is 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

On-Command 4WD

Push-button servo-controlled On-Command system enable you to switch between 2WD, limited-slip 4WD and fully locked differential 4WD – all with the simple push of a dash mounted button. Real 4WD when you need it. With Diff-lock engaged, you have traction to all 4 wheels, immediately. You decide when you need 4WD, the machine doesn’t decide for you.

Ultramatic Transmission

The fully automatic Ultramatic transmission is not only versatile and easy to use, it is also known to be one of the most reliable transimissions in the ATV business. That’s because all Ultramtics are designed to maintain constant belt tension. This means the belt does not have to slip for the ATV to come to a stop, which dramatically improves belt reliability and durability. It also means that Ultramatic transmissions provide continuous and predictable off-throttle engine braking, which can really help when negotiating difficult terrain. The Kodiak 450 also comes with an automotive style transmission lever with a parking lock mechanism, so you don’t have to worry about setting a separate parking brake every time to get off the ATV.

Cooling System

The high-capacity cooling system with high-mounted fan-cooled radiator delivers consistent engine performance, excellent durability and protection from sticks and rocks.

Independent Rear Suspension

Independent rear suspension with sway bar for limited chassis roll provides great terrainability.

Speed Override

Differential lock speed override switch (forward only) allows the rider to override the speed limiter for certain conditions.

Electric Start

Convenient electric starting from any gear.


The new computer-designed steel tube frame is now one piece, and comes with a new rear sway bar that is 20% stiffer for improved handling and cornering. This frame is 6 lbs lighter and retains the rubber engine mounts for a rugged, durable design and reduced vibration.

LCD/LED Information Centre

Digital information centre LCD display for speed, odometer and On-Command functions, as well as LED warning lamps.

DC Terminal

12-volt D.C. terminal provides a convenient power source for accessories such as cellular phones, handheld lights or GPS.

Rear Wet Brake

Rear wet brake uses friction plates immersed in an oil bath and is sealed to keep out water and debris. This provides consistent braking performance, regardless of riding conditions. And since the braking force is amplified through the gear ratio so less effort is required.

Additional Features

Internal engine counterbalancer minimizes engine vibration to rider

Spin-on oil filter simplifies oil changes

High-positioned carb air intake and clutch intake and exhaust vents prevent water from entering carb or V-belt cover

4WD front differential lock. Positive mechanical lock-up for maximum traction in 4WD.

Wide Grizzly type front fenders and new bumper design with excellent mud and splash protection

Dual 30-watt sealed headlights with replaceable bulbs provides excellent lighting, prevents water penetration and simplifies maintenance and reduces cost

25-inch tires with aggressive tire tread pattern for great traction and excellent durability

Sealed marine-style electrical connectors prevents water from entering electrical components and wiring
