Sun Coast Cycle Sports carries used OEM parts for the Yamaha Kodiak, the utility ATV family Yamaha has produced since 1993. The Kodiak name spans several displacement classes across its history: the original Kodiak 400 (YFM400, 1993-2006), the Kodiak 450 (YFM450, 2003-2014), and the current Kodiak 700 (YFM700, 2016-present). All have been positioned as dependable work-oriented 4x4 ATVs with Ultramatic CVT transmissions, selectable 2WD/4WD, and shaft drive. The Kodiak 400 won ATV Magazine's "ATV of the Year" in 2000 and helped establish Yamaha's reputation for bulletproof utility quads. Parts from our inventory are inspected by our Odessa, Florida technicians and listed with individual photos.
Kodiak models and parts compatibility
| Model | Years | Engine | Notes |
|---|
| Kodiak 400 (YFM400) | 1993-2006 | 401cc liquid-cooled single | Ultramatic CVT, selectable 2WD/4WD, shaft drive. Also available in 2WD |
| Kodiak 450 (YFM450) | 2003-2014 | 421cc liquid-cooled single | Enlarged Kodiak 400 engine, IRS on later models, optional EPS |
| Kodiak 700 (YFM700) | 2016-present | 686cc liquid-cooled single | Shares 686cc engine with Grizzly 700, EPS standard or optional |
The Kodiak 400 and Kodiak 450 share the same engine family at different displacements. Some engine internals and chassis components may cross between the two, but the 450 received progressive updates including independent rear suspension that the early 400s lacked. The Kodiak 400 engine is also related to the Big Bear 400 and Wolverine 450 platforms. The Kodiak 700 is an entirely different platform sharing its 686cc engine with the Grizzly 700, Viking 700, and Wolverine 700. The Kodiak 700 has consistently used the 686cc engine even during the 2016-2018 period when the Grizzly briefly used the 708cc Subaru variant. Within each Kodiak model (400, 450, 700), parts interchange freely across all production years of that specific displacement.
Common Kodiak failure points and replacement parts
CVT belt wear (all models): The Ultramatic CVT belt is the primary drivetrain consumable across all Kodiak models. Work-duty use with heavy loads, plowing, and towing accelerates belt wear. Regular inspection and proactive replacement are essential maintenance.
Starter clutch wear: The one-way starter clutch can wear over time on all Kodiak models, causing the starter to spin without engaging the engine. This is a known Yamaha ATV issue and requires flywheel cover removal for replacement.
Carburetor issues (Kodiak 400/450): The carbureted Kodiak models are susceptible to ethanol damage and stale fuel buildup. Machines that sit between seasons frequently need carb service to restore proper running.
Wheel bearings and CV joints: The 4WD system's wheel bearings and CV joints wear under off-road conditions, especially in wet and muddy environments. These are routine replacement items on any Kodiak with significant trail hours.
Commonly replaced Kodiak parts
- CVT drive belt and clutch components
- Starter clutch and starter motor
- Carburetor rebuild kits (400/450) or fuel injection components (700)
- Wheel bearings and CV joints/boots
- Brake pads and brake calipers
- Plastics, fenders, and racks
- Shaft drive seals and differential fluid
- EPS motor and controller (EPS models)
Frequently asked questions
Q: Does the Kodiak 700 share parts with the Grizzly 700?
The Kodiak 700 and Grizzly 700 share the same 686cc engine family, Ultramatic CVT, and On-Command 4WD system. Many engine, transmission, and drivetrain components interchange between the two. The Grizzly is positioned as the more trail/recreation-oriented model while the Kodiak is work-focused, with differences primarily in suspension tuning, accessories, and trim levels rather than core mechanical components.
Q: Are Kodiak 400 and Kodiak 450 parts interchangeable?
The Kodiak 400 and 450 share the same engine family at different displacements. Some engine and chassis components cross between the two, but the 450 received updates including independent rear suspension on later models. Confirm specific part numbers rather than assuming full compatibility.
Q: Does the Kodiak share parts with the Big Bear?
The Kodiak 400 and Big Bear 400 share the same engine family and some chassis components. Many parts cross between the two models. The Kodiak was generally positioned slightly upmarket from the Big Bear with more features and refinement, but the mechanical underpinnings overlap significantly.
