Vehicle Information
Yamaha Kodiak 400 ATV (1993-2006)
The Yamaha Kodiak 400, produced from 1993 to 2006, established itself as a reliable and versatile ATV, ideal for utility tasks and trail riding. Throughout its production, it consistently featured a 401cc single-cylinder, 4-stroke engine, known for providing ample power for its intended use. A significant evolution occurred in 2000. Models from 1993 to 1999 were equipped with an air-cooled engine and a 5-speed transmission. From 2000 onwards, the Kodiak 400 received a major update, introducing an all-new liquid-cooled engine for quieter operation and increased power. This update also brought Yamaha's innovative Ultramatic™ transmission, offering superior engine braking and durability. Four-wheel-drive models from 2000 also benefited from the On-Command™ push-button 2WD/4WD system, along with upgraded hydraulic disc brakes and improved suspension. Q: How do I ensure I select the correct parts for my Kodiak 400? A: Due to significant changes in transmission and cooling systems, always use the year and trim selector on this page to find parts specifically designed for your ATV.
Q: Are parts interchangeable between early and later models? A: No, many components, especially for the engine and transmission, are not interchangeable between pre-2000 air-cooled models and post-2000 liquid-cooled Ultramatic models. Please use the selector.
