If there is an ATV that has proven its overall effectiveness as a workhorse and multifunctional recreational vehicle, that’s going to be the Yamaha Kodiak 400. Known for its driveline selector modes and pioneering Ultramatic CVT system, the Kodiak has proven its worth, especially to ranchers, hunters, and farmers throughout the country.
The Yamaha Kodiak has garnered the respect of the ATV community because of its versatility and impressive qualities, such as its efficient and user-friendly features, among others. With its four-stroke, 401-cc, single overhead cam (SOHC) engine, this quad is a beast when you’re traversing across grassy plains, hard packs, or even snowy and muddy terrains.
Placing the easy-to-operate Ultramatic transmission on the left side of the vehicle earned the appreciation of the public because this design kept the rider’s right hand on the throttle lever. Also, the Kodiak’s combined use of the sprag and centrifugal clutch provided a smoother operation and reduced belt wear when upshifting and downshifting. These features gave the Kodiak 400 the recognition it deserves against other competing quads.
First launched in 1993, the Kodiak is first marketed as a multipurpose, hardworking quad. With its remarkable off-road and heavy-lifting capability, coupled with its reliable handling and innovative transmission system, this four-wheeler can step alongside the ranks of the Trail Boss, Rancher, or the FourTrax. Furthermore, the vehicle’s on-the-fly 2WD and 4WD drivetrain selector enables operators to traverse any terrain with ease, making the quad an all-around machine for trail explorations and other adventurous activities.
The more superior Yamaha Kodiak 450 took over the lineup as the 400 closed the curtains in 2006 after a lengthy 13-year production run. Nevertheless, the Yamaha Kodiak 400 continues to charm its admirers with its convenient and cutting edge controls, reliable and durable design, and a lasting legacy that can compete with any off-road during its heyday.

Primarily built as a transport and towing quad for hunters, ranchers, and other hardworking folks, the Yamaha Kodiak 400 also catered to people who enjoy exploring trails. With a near-bulletproof engine, great handling capability, and a single-speed constant mesh transmission system, the Kodiak proves that it’s a heavy-duty vehicle for grunt work.

Additionally, this all-terrain vehicle requires a fuel stabilizer if you plan to store your Kodiak for a long period without draining out the fuel. The amount of fuel stabilizer required per litre of fuel is 1.0 fl. oz. (7.5 cc).
For the Yamaha Kodiak 400’s wet-sump lubrication system, the engine uses Yamalube 4 or SAE 10W-30 oil. The oil should have a JASO T903 MA, MB classification, API grade. Other oil types, such as the SAE 5W-30, 20W-40, are ideal alternatives. However, the usage of these oil variants is dependent on the outdoor temperature. Make sure that the engine oil does not have the “Energy Conserving II” label on it.
For the differential gear oil, using SAE 80 API GL-4 Hyploid gear oil is recommended. If the GL-4 classification is not available, GL-5 or GL-6 are also acceptable alternatives for the Kodiak.
As for the Kodiak’s amount of oil required, a periodic oil change requires 2.3 litres (2.4 US quarts) and a filter change necessitates 2.4 litres (2.5 US quarts). On the other hand, 2.6 litres (2.7 US quarts) is needed when conducting an overhaul.
The Yamaha Kodiak 400 uses an electronic starter switch, which is connected to the capacitor discharge ignition (CDI) system. Additionally, the quad is also equipped with a supplementary recoil pull starter, which serves as a backup in case the battery does not work.
This rec-utility ATV has an AC magneto as its generator system and uses an NGK DR8EA spark plug with an electrode gap specification of 0.6 (0.02 inches) ~ 0.7 mm (0.03 inches). As for the battery, the Kodiak uses YTX20L-BS with a 12 V, 18 Ah capacity.

The Yamaha Kodiak 400’s reliable handling comes mainly from its superior suspension system. This mean machine has an independent, dual A-arm, double-wishbone front suspension, while the rear suspension has a steel, swing arm design. The front A-arm suspensions of a stock Kodiak has front skid plates, which offer better protection.
Each suspension system is fitted with a pre-adjustable fork preload with coil spring and oil damper. The front wheel has 6.3 inches (160 mm) of travel. The rear wheel, on the other hand, has 7.1 (180.3 mm). Additionally, the 400 has a decent turning radius of 9.8 feet.
A stock Yamaha Kodiak 400 is fitted with a set of puncture-resistant, tubeless KT123 Dunlop AT 25 x 8-12 front tyres, while the KT127 Dunlop AT 25 x 10-12 for the rear. Both the front and rear tires require the same air pressure, which should be 25 kPa (0.25 kgf/cm2, 3.6 PSI). It is recommended that the tyre air pressure should be changed accordingly in case the tyres have been exposed to cold temperatures.
During instances in which the air pressure should be decreased, the minimum tyre air pressure for each tyre should not go below 22 kPa (0.22 kgf/cm2, 3.2 PSI). Furthermore, when seating the tyre beads, the tyre air pressure should not go below or higher than 250 kPa (2.5 kgf/cm2, 36 PSI). Note that the process of inflating the tyres should be done carefully and slowly or the tyre might burst.
The Kodiak 400 is equipped with a dual hydraulic disc front brake, which can be operated using the right-hand lever. The sealed drum disc rear brake, on the other hand, can be operated using a left-hand lever or right-foot pedal.
Load and Towing Capacity

The maximum capacity of the hitch tongue is 33 lb (15 kg). Apart from this, both the front and rear tube racks can handle 88 lbs. (40 kg) and 176 lbs. (80 kg), respectively. The quad also has a storage box that can take in 4.4 lbs. (2 kg). This quad has a dry weight of 514 lbs. (233.2 kg) and a curb weight of 584 lbs. (265 kg).
The Yamaha Kodiak 400 has an overall length of 78.1 inches (1,984 mm), a height of 44.1 inches (1,120.1 mm), and a width of 42.7 inches (1,084.6 mm). This one-seater has a seat height of 32.6 inches (828 mm). The quad’s wheelbase is 48.5 inches (1,231.9 mm), while the ground clearance comes in at 9.7 inches (246.4 mm), which isn’t much of a tall order, considering that the Kodiak is a massive off-roader.
The quad’s steel chassis and plastic body are equally durable, much to the appreciation of Kodiak enthusiasts. The Kodiak’s frame has a caster angle of 4° and a 21-mm (0.83-inch) trail. While the Yamaha Kodiak 400 has different colour options, the units with a camouflage pattern are exclusive only to special edition models.
The Kodiak’s handlebar controls consist of a light switch with high and low beam options, an engine stop switch, and a start switch. The front and rear brake levers, speed limiters, and the 2WD/4WD driveline selector switch are also located in the quad’s handlebar.
Moreover, this 514-pounder also has a rear brake pedal, floorboards, and indicator lights for the water temperature and drive select switch. Apart from that, the stock 400 comes with front and rear fenders, bumpers, as well as a front bash plate, and skid plates for the dual A-arms.

How Fast Can a Stock Yamaha Kodiak 400 Go?
On a dirt road, a bone stock Yamaha Kodiak 400 can go from 45 to 55 miles an hour. Conversely, this utility workhorse can go from 65 to 67 mph on a hard-pack trail. However, there are several outside factors that can affect the quad’s speed regardless of the terrain.
Often, the type, size, and weight of the tyres can affect the Kodiak’s performance. In addition, the upgrades or mods installed in the four-wheeler also play a huge role in the 400’s output.
For anyone keen on upping the speed to their Yammie 400, experts and vets would typically recommend a usual concoction of aftermarket components for utility ATVs. These mods involve high-quality K&N air filters, slip-on exhausts, and a jet kit. The only tradeoff, if you have these upgrades on your Kodiak, would be a louder engine.
What Are the Pros and Cons of the Yamaha Kodiak 400?
There isn’t much that can be said about the Yamaha Kodiak 400 considering that it’s an exceptional utility ATV that can be used in different activities. Whether you like to ride and explore trails or perform a lot of heavy work, the 400 is the perfect quad for these occasions.
However, this heavy-duty vehicle isn’t blessed with the best of both worlds. The more these flaws will become more noticeable since we’re dealing with old ATV variants. With that said, below are some of the pros and cons of the Yamaha Kodiak 400.
Robustness and conquering virtually impassable terrains aren’t just this four-wheeler’s forte, as the Kodiak has several conveniences hidden under its sleeve. One of these surprising features is the seat. Several owners are always blown away at how comfortable this all-terrain vehicle can be—a feature that many riders can attest even to this day. Also, the Kodiak 400 has a no-maintenance driveshaft, which gives operators one less thing to worry about.
High Ground Clearance
As a utility off-road vehicle, high ground clearance is definitely a plus for the Yamaha Kodiak 400 as this feature allows the quad to traverse across any rough terrain. Whether you are headed to a muddy or rocky trail for a hunting trip or leisurely exploration, the Kodiak is sure to get you to your destination and back.
Apart from the ground clearance, the Kodiak 400’s superb handling is worth noting just as its ability to clear out any trail, thanks to its superior suspension system. The dual A-arms and the swing arm work well with the vehicle’s powertrain, giving the rider a smoother, reliable ride throughout.
No Front Differential
With its impressive handling capabilities and reliable suspension system, the Kodiak can be a great quad for mudding and other activities. However, these terrains may require more traction capability, something which the Yamaha Kodiak 400 might struggle with as it has no limited front differential. Though the lack of which can pose a problem to some owners, it takes a highly experienced rider to get out of any sticky situation.
Choke Cable Freezing Up
A lot of owners have complained about the choke cable getting frozen up in cold weather. Though a frozen choke isn’t supposed to be a problem in most cases, this can be an issue in cases of emergencies. That’s because a blocked choke would end up with you either running rich or lean, which is not good for the Kodiak’s engine.
In case this happens, you can turn the quad’s engine on and warm up the cable. You may also place the ATV in a warm area, such as in a shed or garage. A blow dryer can also do the trick.
