With full-length skidplates as standard, almost 10-inches of ground clearance, and independent double wishbone suspension including adjustable shocks, the Yamaha Kodiak 450 EPS SE is ready to take on rugged terrain without breaking a sweat—and with rider comfort that makes long rides a joy, too.

The Kodiak 450 EPS SE, unlike many other middleweight utility ATVs, isn’t simply a smaller engine hidden under a full-size body. The Kodiak 450 EPS SE was designed from the ground up to provide riders with a small chassis for excellent trail handling and agility like in 2020 Yamaha Kodiak 450 EPS SE.

The ergonomics of the Kodiak 450 EPS SE have been intended to let riders of all sizes get the most out of it. Thanks to a long, comfy seat and broad floorboards, riders of all sizes have plenty of space to move about. The handlebar bend of the Kodiak 450 EPS SE is designed for riders of different heights to enhance comfort.

From the new tool-less air filter design and oil drain ports to the high-attached air intakes and marine-grade electrical connections, the Kodiak 450 EPS SE utilizes various features to enhance longevity and serviceability, much like other Yamaha ATVs and side-by-sides.


The Kodiak 450 EPS SE has 9.6 inches of ground clearance and full-length composite skid plates for optimum underbelly protection in a range of conditions.

Yamaha’s Electric Power Steering offers the most acceptable combination of steering help and positive feedback in the industry by monitoring gear position, 4WD mode, and speed in real-time to adapt to terrain conditions.

Yamaha designed the Kodiak 450 EPS SE with a compact body design that is considerably less bulky than competing models for accurate handling and confidence-inspiring riding in various terrain situations.

The torquey 421cc SOHC engine on the Kodiak 450 EPS SE is intended to offer a mix of immediate power and smooth character for extended rides with minimum strain. Easy cold starts and faultless fuel delivery in almost any circumstance are made possible with Mikuni® fuel injection. At the same time, liquid cooling and a high-volume fan system guarantee dependable, consistent performance for years to come.

The Ultramatic® gearbox has a gated shifter, park, dual-range (Hi/Lo) drive, and reverse gear and is designed to offer lower cruising rpm for smooth and quiet operation. The location of the gated shifter was also carefully studied, and it was relocated forward to give more space for the rider.

The On-Command® 4WD technology on the Kodiak 450 EPS SE enables you to choose between 2WD, limited-slip 4WD, and completely locked differential 4WD with the press of a button. An override button allows the engine to attain maximum rpm in full diff lock mode. This driver-controlled technology avoids the stuttering or sliding that may occur while waiting for computer-controlled systems to activate, as seen in specific rival models.

The sealed rear brake is shielded from dirt, pebbles, and mud, while the hydraulic front disc brakes provide a reliable and robust feel and braking performance. The Kodiak 450 EPS SE adds style and trail-proven toughness to the rolling stock. Rugged 25-inch tires with an aggressive tread pattern provide a mix of accurate steering and optimum comfort to maximize available traction, while robust but light aluminum wheels will last for years.

Steel cargo racks with wide diameters and a durable wrinkle paint finish can carry a total of 264 pounds. The Kodiak 450 EPS SE comes equipped with a heavy-duty ball mount, allowing it to pull up to 1,322 pounds.


The Kodiak 450 EPS SE has the same spacious riding posture as the bigger Kodiak 700. Every element of the Kodiak 450 EPS SE was intended to offer class-leading levels of refinement to the middleweight 4×4 ATV category, including tall handlebars, a long and plush seat for enhanced rider comfort for extended work days, big textured floorboards, and a more oversized thumb throttle.

The Kodiak 450 EPS SE has specially designed rubber engine mounts that isolate engine bay vibrations and provide one of the smoothest rides ever offered in a utility ATV.

The independent double-wishbone suspension on the Kodiak 450 EPS SE provides an optimized vehicle stance, light steering, and better shock feel throughout the full range of travel. Even in the most challenging terrain, the Kodiak 450 EPS SE offers excellent rider comfort with 6.7-inches of front wheel travel and 7.4-inches at the rear.

With predictable steering assistance that adjusts to changing riding circumstances for an incredible sense of control, Yamaha’s Electric Power Steering substantially decreases fatigue.

The additional halogen work light placed on the handlebar beneath a body-color-matched cowl provides increased visibility and lighting to Kodiak 450 EPS SE users. In a contemporary and small design, a tiny all-LCD instrument cluster provides the rider a clear view of speed, gearbox condition, fuel level, and more.

Over a long riding day, a conventional 12V power connection makes it simple to keep electronics charged. During your trip, you may store different things in the undersea storage compartment.


Yamaha’s Ultramatic® gearbox earned its reputation as the most dependable on the market. A sprag clutch delivers Yamaha’s famous all-wheel engine braking, while an automated centrifugal clutch maintains consistent belt tension for decreased belt wear.

The Kodiak 450 EPS SE includes high-mounted air intakes to prevent water and debris from entering the drive system or engine air cleaner, as well as a reusable foam air filter for the engine side that is reachable without tools. These air passages provide lots of fresh, clean air to the engine and keep the V-belt cool even under the most extreme circumstances. Yamaha ATVs include marine-grade waterproof connections for optimum weather protection, as well as increased durability and serviceability.

The powertrain of the Kodiak 450 EPS SE is intended to make servicing and maintenance as straightforward as possible. The airbox provides tool-less access to the air filter element, and the engine and differential provide handy oil drain holes. Vehicle electronics are placed high on the chassis beneath the front center panel for easy access. Uniquely textured, injection-molded fenders guard against rock and debris damage and keep looking good season after season, taking design elements from Yamaha’s industry-leading line of big-bore ATVs.

The Kodiak 450 EPS SE is ready to be customized to fit almost any task, from towing and field work to hunting and leisure riding, with winch wire pre-installed at the factory and a selection of Genuine Yamaha Accessories, developed in conjunction with the machine. In Newnan, Georgia, USA, Real World ToughTM was assembled.

With a factory-installed WARN® VRX 2500 winch, the Kodiak 450 EPS SE further improves rough terrain capabilities and confidence, increasing rider confidence in the most challenging circumstances.

To maintain appropriate temperatures, the Kodiak 450 EPS SE gearbox has its cooling intake, a more oversized belt to withstand the torque of the enormous engine, and Yamaha’s innovative sprag clutch to keep belt tension constant. The final result is a powertrain designed to provide years of trouble-free service and is guaranteed by the industry’s first 10-Year V-Belt Limited Warranty.
