One of Kawasaki’s most-loved supporting vehicles is the Kawasaki Prairie 300 4×4. Considered a niche quad, it catered to off-roaders and nouveau riders who preferred to enjoy the outdoors on a practical, no-shift wheeler with tons of power.
The Kawasaki Prairie 300 4×4 is a rec-utility vehicle that was introduced to the public in 1999. Designed to supplement its bigger-displacement siblings, it featured a fully-automatic V-belt transmission, impressive hauling capabilities, and 2WD/4WD modes with a limited-slip front differential.
Aside from these features, the Prairie 300 was also known for its hardy stance, dependability, and rugged aesthetics – qualities that avid Kawie followers loved. Read on and learn about the specs, features, and other endearing attributes of this uncomplicated, no-nonsense four-wheeler.
About the Kawasaki Prairie 300
The Kawasaki Prairie 300 4×4 was launched alongside the successful Prairie 400 – from 1999 to 2002. The idea behind this 300-class machine was to offer big-bore features to enthusiasts and general consumers who preferred something smaller that was not gear-driven but could still function as a rec-utility vehicle.
The Japanese manufacturer introduced the 4×4 to the public as one of its value ATVs to increase its market share in the industry’s largest sales segment.
Often compared to the Bayou 300, the Prairie 300 used a similar 290-cm3 4-stroke SOHC engine, chassis, tire-wheel system, and suspension components. Its drive system consisted of the same belt drive torque converter (later called Kawasaki Automatic Powerdrive System or KAPS in 2011) as in the Prairie 400 but tuned to specifically match the quad’s power output. Shared features with its siblings include front and rear composite game racks and full-time 4WD with a lockable front differential.
Despite having a short production run, the Prairie 300 left such an impression with the off-roading community that Kawasaki ended up releasing a revamped version of the vehicle – the Kawasaki Prairie 360.
This machine sported K-EBC™, a bigger engine displacement, and improved top-end speed while retaining its predecessor’s other rock-solid features. For many, the 360-cm3 vehicle seemed to be a compact version of the V-Twin behemoths. But for knowing Kawie riders, it was more reminiscent of the Kawasaki Prairie 300 4×4.
Kawasaki Prairie 300 Specs & Features
The 4×4’s engine is powerful and has a fuel capacity that is not very far from the tank capacity of its 360-class successor, given the difference in engine displacement.
Like other Kawasaki ATVs, the machine requires a fuel stabilizer mixed with gasoline, especially when storing the Prairie 300 for long periods, to prevent fuel oxidation and gummy deposits.

|Turning Radius||3.5 m (11.5 ft) – KVF300-A; 3.4 m (11.2 ft) – KVF300-B|
|Front Suspension Type, Travel||MacPherson Strut, 170 mm (6.7 in)|
|Rear Suspension Type, Travel||Aluminum swingarm w/ 5-way adjustable spring preload, 180 mm (7.1 in)|
Because the Kawasaki Prairie 300 is slightly shorter than the Prairie 360, minimum clearance is closer to the ground and may not always be ideal for steep, rock-crawling sections.
A quick remedy to this dilemma is getting a 2-inch lift kit (view on Amazon) or a full skid plate to protect the underside of your quad.

You will find that most good shape units have been exclusively used in the farm or for enforcement patrol. They have fresh tires and come complete with front and rear cargo racks. Some have sturdier aftermarket drop baskets (view on Amazon).
For those who already own a Kawasaki Prairie 300 and are in the middle of a build project, you can find old quads online being sold for parts for $300 or less.
Kawasaki Prairie 300 Problems
Secondhand wheelers usually carry this problem, which manifests through different symptoms. Some owners may notice that their vehicle is not turning over or idling erratically. Others may experience fuel leaks and abrupt power loss while riding or after releasing the throttle.
While this problem can affect any pre-loved quad, Prairies with engines that are either modded or swapped out (for a variant meant for a different ATV make and model) and those that have sat for a while have a higher tendency to experience it.
If you suspect having this dilemma, there are a few things you can check to narrow down the problem source:
- Does your machine rev freely without being in gear? If so, the problem might be CVT-related. Pull off the clutch cover and inspect if your belt is in good shape.
- Has your vehicle had a lot of frequent use? If so, check on the primary clutch spring, ramps, and weights of your quad, and see if these Kawasaki Prairie 300 parts are correctly functioning.
- Do you have any fluid in the floats? To answer this, you will need to check if your machine’s float adjustment is according to spec (so that fuel does not overfill), especially if it has gone through a carb rebuild.
Knowing whether the vehicle was stored with fuel inside the tank or not would tremendously help in this situation, too. This would involve a complete disassembly of the Kawasaki Prairie 300 carburetor, removing all jets and internal components, thoroughly cleaning these parts with a tested carb cleaner and a fine copper wire (to unclog the circuitry above the pilot jet and behind the air screw). If the steps above don’t solve the issue, then the probable cause is likely a compression issue.
Resolving a carb issue sometimes leads to this problem, which leaves Prairie owners perplexed since they have just done a thorough cleanup of their carb and its components.
Unluckily, the thing with Kawasaki Prairie 300 carburetors is that they do not have a replaceable float needle valve seat. Hence, any scratches or erosion on the valve seat may lead to flooding. Either that or the small clip that fits on the float tang and connects to the needle valve is not installed the right way.
It is also possible that the float and float needles themselves are severely worn, or the float tang has been bent when working on the carb.
There are cases when fixing a flooded engine is not enough, and the issue with your Prairie 300 turns into misfiring/backfiring. While we all easily conclude incorrect valve timing or a poorly tuned carb to be the issue, the fix could just be to replace the spark plug.
Bear in mind (with any ATV) that a spark plug with spark is not guaranteed to work properly. Checking if the spark plug gets wet when starting the vehicle will tell you this. Otherwise, you may want to check your fuel valve, filters, and carburetor float level all over again. By this time, you may need a different set of eyes to help you diagnose the problem.
Steering Knuckle Issue
Kawasaki voluntarily recalled about 155,000 units of Prairie 300/300 4X4, Prairie 360/360 4X4, Prairie 400/400 4X4, Prairie 650 4X4, Prairie 700 4X4, and Brute Force 650 4X4 (2001-2005 models) due to an assembly flaw affecting the front wheel of the ATVs. The ball joint of recall-affected models tends to separate from the steering knuckle, resulting in loss of steering control and potential rider hazard.
A total of 39 warranty claims and three personal injury claims are related to the said issue. As a fix, dealers nationwide replaced the ball joints and steering knuckles on KVF300A/B and KVF400A/B versions and the ball joints, steering knuckles, and lower A-arms for all other models.
