DO-IT-ALL ATV. With an Ultramatic® automatic transmission, On‑Command® 2WD/4WD and fuel injection, this ATV packs big performance into a mid‑size machine.
The Ultramatic® transmission is specifically tuned to provide lowered cruising rpm for smooth, quiet operation, and features a gated shifter with park, dual-range (Hi/Lo) drive and reverse gear. Even the position of the gated shifter was carefully considered, being moved forward to provide a roomier rider area.
COMFORT
The Kodiak 450 offers a riding position with the same roomy feel as the larger Kodiak 700. With tall handlebars, a seat that is long and plush for improved rider comfort, and large textured floorboards, every aspect of the Kodiak 450 was designed to bring class-leading levels of refinement to the middleweight 4x4 ATV segment.
CONFIDENCE
Yamaha ATVs feature marine-grade waterproof connectors for maximum weather-proofing, increased durability and improved serviceability.
CONFIDENCE
The Kodiak 450 transmission uses its own cooling intake to maintain proper temperatures, an oversized belt to handle the torque of the large motor and Yamaha’s unique sprag clutch to maintain constant belt tension. The end result is a drivetrain built for years of trouble-free service that leaves the competition in the dust, and is backed by the industry's only 10-Year V-Belt Limited Warranty.
