The Kodiak 450’s ergonomics were designed to allow riders of all sizes to get the most out of it.

For precise handling and confidence-inspiring riding in various terrain conditions, Yamaha developed the Kodiak 450 with a compact body design that is much less bulky than rival models.

The Kodiak 450’s torquey 421cc SOHC engine is designed to provide a combination of rapid power and smooth character for long days of riding with little effort. Mikuni® fuel injection allows for easy cold starts and flawless fuel delivery in virtually any situation. At the same time, liquid cooling and a high-volume fan system provide reliable, consistent performance for years to come.

The Ultramatic® gearbox has a gated shifter, park, dual-range (Hi/Lo) drive, and reverse gear, as well as low cruising rpm for silent operation. The position of the gated shifter was also carefully considered, and it was moved forward to offer the rider more excellent room.

On-Command® 4WD is a Yamaha-exclusive function. With On-Command® 4WD technology, you can switch between 2WD and limited-slip 4WD with the push of a button on the Kodiak 450. This driver-controlled technology eliminates the stuttering or sliding that may occur while waiting for computer-controlled systems to turn on, as observed in certain competitor vehicles.

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 under-seat 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 has high-mounted air intakes to prevent water and debris from entering the drive system or engine air cleaner. The engine side has a reusable foam air filter that can be accessed 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.

With design elements taken from Yamaha’s industry-leading line of big-bore ATVs, the fenders are uniquely textured and injection-molded to guard against rock and debris damage and keep looking good season after season.

The Kodiak 450 is ready to be customized to fit almost any task, from towing and fieldwork to hunting and leisure riding, with winch wire pre-installed at the factory and a variety of Genuine Yamaha Accessories, developed in conjunction with the machine.
