Now let’s take a deeper look at how this exciting machine performs on trails and off-road.

Kawasaki Mule SX Top Speed

One of the most impressive specs on the Mule SX is its top speed for a UTV. However, this side-by-side can reach up to 25 mph at top speed.

That makes it one of the reliable rec-utility UTVs you can buy from a major manufacturer like Kawasaki.

The Mule SX achieves its performance thanks to the 401cc single-cylinder engine. This motor provides good low-end power and torque, which helps this model to power through most mud, sand, puddles and up steep hills.

Paired with the engine is a continuously variable transmission (CVT) for smooth shifting. Switching between high and low gearing is easy to manage your speed over different terrain.

In addition, the Mule SX has 2WD and 4WD modes. Use 2WD on firm trails to go faster by reducing drivetrain drag. Flick on 4WD whenever you need maximum traction in mud, snow, or sandy surfaces.

The combination of a less-powerful engine and a speed governor restrict it to a top speed of 25 MPH.

Kawasaki Mule SX Engine Specs

Now let’s look under the hood and break down the engine powering this side-by-side.

The Mule SX runs a 401cc air-cooled 4-stroke single-cylinder engine. This OHV motor provides good low-end power and torque while meeting current emissions standards.

Here are the key engine specs:

• Displacement: 401cc
• Cooling: Air-cooled
• Valvetrain: OHV (overhead valve)
• Fuel System: Nikki 6C1026
• Maximum Torque: 21.4 lb-ft @ 2400 rpm

That amount of torque gives you strong acceleration whether climbing steep hills or traversing trails. The single-cylinder design results in a reliable engine character that’s easy to maintain.

The engine uses a wet sump lubrication system for better durability when riding over bumpy terrain and inclines. Oil flow keeps everything lubricated.

To handle engine heat, there’s a large fan directing air over the engine. Air flow keeps operating temperatures stable even when working hard.

Overall, the 401cc single has the performance to deliver reliable speed and acceleration for the Mule SX. This motor is designed for durability and ease of maintenance.

Kawasaki Mule SX Chassis And Towing

In addition to a powerful engine, the Mule SX needs a robust chassis and drivetrain to handle rugged recreational riding. Kawasaki built this side-by-side to last on the trails.

The Mule SX features a compact steel frame that provides rigidity and strength. Steel construction ensures durability for taking abuse from rocks, ruts, and jumps.

Suspending the chassis are MacPherson Strut/3.1 in front suspension and Unit Swingarm/3.1 in rear suspension.

In terms of ground clearance, the Mule SX gives you 8.1 inches. That’s ample room for clearing obstacles like rocks and fallen tree branches on the trail.

Other drivetrain specs include:

• Front Tires: 26×9.00-12
• Rear Tires: 26×9.00-12
• Fuel Capacity: 4.2 gal
• Turning Radius: 11.8 ft

Now let’s discuss towing capacity, which is important if you need to pull a trailer with camping gear, dirt bikes, etc.

The Mule SX can tow up to 1,100 pounds. That’s enough for a loaded single-axle trailer. A standard 2 inch hitch receiver allows you to equip a ball mount and wiring.

The sturdy chassis, quality suspension, and towing power make the Mule SX ready for off-road adventures far from civilization. You can rely on this side-by-side to get you there and back safely.

Kawasaki Mule SX Comparison with Polaris RZR and Can-Am

The Mule SX is a direct competitor to sporty recreational models from Polaris and Can-Am. Let’s see how it stacks up.

Polaris RZR 800

The Polaris RZR 800 runs a slightly smaller 760cc twin-cylinder engine with 46 HP. It’s down on power compared to the Mule SX, which has a 401cc single-cylinder engine.

On the plus side, the RZR 800 has better high-speed suspension tuning and 13.5 inches of ground clearance. It handles rough terrain at speed better thanks to its long travel Walker Evans shocks.

The RZR 800 is wider at 64 inches versus 52.6 inches for the Mule SX. And it can carry more cargo weight. But it tows less at 1,500 pounds max compared to the Mule SX’s towing capacity of 1,100 pounds.

For a starting MSRP of $13,399, the RZR 800 costs around $500 more than the Mule SX. You get upgraded suspension for that extra bump in price.

Can-Am Defender HD8

The Can-Am Defender HD8 runs a smaller and slower 799cc twin-cylinder engine. The Defender HD8 is geared more for utility work than recreation.

But it does offer excellent cargo and towing capacities of over 1,500 pounds. And size-wise the Defender HD8 slots between the 2-seat and 4-seat Mule SX models.

One advantage of the Defender HD8 is better ride quality at high speeds thanks to its advanced high-end shocks. It also comes standard with nice features like power steering.

The Defender HD8 starts at an MSRP around $15,000. So you’ll pay over $2,000 more than a base 2-seat Mule SX. But some buyers prefer the Defender’s utility capabilities and plush ride comfort.

Overall the Mule SX holds its own against these two competitors. It offers superior engine power, speed, and acceleration compared to the RZR 800 and Defender HD8.

The Mule SX is the sporty high-speed recreation choice. Go with the RZR 800 if you value extreme terrain handling or the Defender for utility strength.

What Owners Are Saying About The Kawasaki Mule SX

With the Mule SX being a brand new model, longer term owner reviews are limited. But initial reactions from new buyers have been overwhelmingly positive.

Here’s what owners like about the Mule SX:

• “This thing rips! Hit 25 mph on first ride. More than enough power bombing through trails and mud holes.”
• “Suspension eats up bumps pretty well. Ride is nice and plush until speeds get above 40 mph.”
• “No problems hauling deer during hunting trips. Hauls a heavy load and trailer with no issues.”
• “Quality is typical Kawasaki – seems very well built. Runs smooth and strong even when working hard.”
• “Great bang for your buck. More capable than expected given the price point.”

Some constructive feedback from owners includes:

• “Steering is too heavy at low speeds without power steering. Can wear you out turning tight.”
• “Shocks are underdamped when hitting bumps and G-outs over 40 mph. Bounces and shakes more than expected.”
• “No engine braking can make it tricky driving downhill. Rolls faster than you may want.”
• “Check valve clearance and adjust as needed after break-in. Easy maintenance.”

Overall owners praise the Mule SX as a fast, nimble, and affordable recreational UTV. They love having single cylinder power and speeds over 25 mph.

Ride quality at higher speeds and lack of power steering are drawbacks. But most accept the trade-offs given the friendly MSRP.

Common Kawasaki Mule SX Problems and Fixes

While too new for widespread long-term reliability data, here are a few potential issues to keep an eye on with the Mule SX.

1. Engine surging at low RPM

Some owners report stumbling and surging from the engine at low RPM, especially when cold. This can cause jerky power delivery until the engine warms up.

• Potential Causes: Lean fuel mixture, low idle speed
• Fix: Adjust air/fuel mixture screw, raise idle RPM setting

2. Engine overheating on long climbs

Climbing steep grades for extended periods can lead to elevated engine temps. Loss of power may occur.

• Potential Causes: Insufficient coolant, plugged radiator screen
• Fix: Top off coolant, check radiator screen and clean if needed

3. Driveline vibration at high speeds

Driveshafts may vibrate excessively at speeds over 50 mph. This causes shaking and rattling sensations.

• Potential Causes: Unbalanced prop shaft, worn U-joints
• Fix: Rebalance or replace prop shaft, check U-joints

4. Rough suspension and handling

Hitting bumps and choppy terrain at high speed can unsettle the UTV and produce a harsh ride.

• Potential Causes: Underdamped shocks, improper tire pressure
• Fix: Upgrade to aftermarket shocks, adjust tire pressure

5. Steering wanders and drifts

Letting go of the steering wheel causes the UTV to wander instead of tracking straight.

• Potential Causes: Misaligned front end, loose tie rods
• Fix: Realign and adjust front end, check tie rod ends

Like any machine, stay on top of maintenance and fixes to maximize reliability. But overall the Mule SX models have proven very durable so far.
