As you can see, top speeds range from 25-45 mph across the Mule family. The PRO-MX and PRO-FXT are the speed demons of the bunch, while the PRO-DXT trades top speed for extreme durability and towing ability.

Below we’ll take a deeper look at the specs and capabilities of the fastest and slowest Mule models. First, let’s overview the key factors that influence Mule top speed and performance.

What Gives Mules Their Top Speed?

Several elements of UTV design determine how fast a Kawasaki Mule can ultimately go:

• Engine size – Measured in cc’s, larger engines produce more horsepower and acceleration. But they can also consume more fuel.
• Horsepower – More horsepower equals faster speed and towing capacity. But requires more engine maintenance.
• Drivetrain – Transmission, gearing, 4WD/2WD impact power delivery to the wheels.
• Vehicle weight – Heavier UTVs require more power to reach top speed. Cargo capacity adds weight.
• Suspension and wheels – Longer travel suspension and larger tires are built for speed over rough terrain.
• Intended use – Some Mules sacrifice outright speed for enhanced utility capabilities.

Next let’s see how these factors come into play for both the fastest and slowest Mule models…

Fastest Kawasaki Mule: PRO-MX Top Speed

The Kawasaki Mule PRO-MX ranks as one of the fastest UTVs in the Kawasaki lineup, with an impressive top speed of up to 45 mph.

Here are the performance specs that give it such speed and quick acceleration:

• Engine: 783cc 3-cylinder fuel-injected engine – The large engine displacement produces ample power. Fuel injection enhances throttle response.
• Horsepower: 48 horsepower – Strong horsepower output for a UTV helps achieve maximum speed.
• CVT transmission: The stepless continuously variable transmission keeps the engine in the optimal RPM range.
• 2WD/4WD modes: Switch between 2WD and 4WD as conditions require. 4WD adds traction to enable more speed off-road.
• Long travel suspension: Over 9 inches of wheel travel soaks up rough terrain at any speed.
• 25″ tires: Large diameter tires roll smoothly over obstacles to maintain momentum.

The PRO-MX packs performance to spare while still retaining a 1,100 pound towing capacity when equipped with Kawasaki’s tow package.

The muscular engine provides quick acceleration to get out ahead on the trails. And equal lengths front and rear suspension arms ensure stability at any speed.

While not the absolute fastest UTV, the Mule PRO-MX strikes an ideal balance of speed, power, and utility. Let’s compare it to another top performer in the Mule lineup…

Slowest Kawasaki Mule Model: PRO-DXT Top Speed

At the opposite end of the speed spectrum from the PRO-MX and PRO-FXT is the Kawasaki Mule PRO-DXT, with a top speed of just 25 mph.

But what it lacks in outright speed, it makes up for in brute strength and unstoppable off-road capability:

• 401cc single-cylinder diesel engine – More torque and low end power than gas engines. But less top-end speed.
• 18 horsepower – Modest power output keeps top speed low. Priority is on pulling power.
• Low range gearing – Excels at crawling over obstacles with maximum control.
• 2,500 lb tow rating – Massive towing capacity paired with diesel torque.
• Independent suspension – Soaks up rough terrain when slowly working or towing.

Clearly the PRO-DXT emphasizes torque and towing over speed. Low gearing gives it incredible control in tricky situations. Independent suspension provides a smooth ride under heavy loads.

And the diesel engine offers next-level durability to withstand backbreaking daily use. It’s built to consistently perform in harsh environments that would sideline lesser machines.

So if you need to tow heavy equipment around a work site or farm at low speeds, the PRO-DXT has the specifications and stamina to handle it. Just don’t expect to win any drag races!

Additional Factors Influencing Kawasaki Mule Top Speed

Beyond the engine and drivetrain, there are a few other elements that can impact how fast a Kawasaki Mule UTV can ultimately go:

Terrain and Conditions

All top speeds listed are approximate maximums in ideal conditions. Real-world terrain and environment will slow any UTV:

• Hills – Climbing steep grades or traversing side hills will require lower gears and limit speed.
• Surface traction – Loose dirt, mud, snow, and rocks reduce traction and cause slipping that slows acceleration.
• Cargo/passenger weight – More stored gear or heavier passengers add weight that the engine must overcome to reach top speed.
• Elevation – Thin air from high altitudes starves the engine of oxygen, reducing horsepower and speed.

Model Year Changes

Kawasaki continually makes minor tweaks and updates to their Mule models year-over-year. These small changes may alter top speed:

• Engine tuning – Adjustments to ECU settings, air intake, and fuel mapping can add or subtract a few HP.
• Updated components – New tires, wheels, suspension parts can enhance speed and handling or be more utility-focused.
• Reduced weight – Mules may drop a few pounds from year to year by using lighter materials. Less weight quickens acceleration.

Aftermarket Modifications

While stock Mule UTVs already offer strong performance, owners can choose to modify them for even more speed:

• Engine tuning computer – Aftermarket ECU reprogramming can boost horsepower above stock levels.
• Exhaust system – Install a less restrictive exhaust header and muffler for added high-RPM power.
• Clutch kit – Upgraded CVT clutch components optimize RPM ranges for faster acceleration.
• Wheel/tire upgrade – Larger aftermarket tires provide more traction and higher top speeds.

Of course such modifications will also reduce reliability and warranty coverage, so weigh the trade-offs carefully!

How Does Mule Top Speed Compare to Towing Capacity?

When choosing a Kawasaki Mule UTV, it’s helpful to consider top speed in the context of towing and hauling abilities. There’s often an inverse relationship at play:

High-speed models like the PRO-MX and PRO-FXT sacrifice some towing capacity (1,100-2,000 lbs) at the expense of achieving 40+ MPH top speeds. Their acceleration and handling is nimble unloaded.

Low-speed models like the PRO-DXT boast massive tow ratings (2,500+ lbs) but have working-grade top speeds around 25 MPH. Their torque excels at hauling heavy loads at slower controlled speeds.

Middle-ground models strike a compromise between speed and working utility. The PRO-DX tows 1,200 lbs at 40 MPH, while the 4010 tows 1,250 lbs at 40 MPH. This balance suits most owners’ needs.

So weigh your priorities for speed versus towing/hauling ability based on how you plan to use your Mule. Zooming around unloaded calls for a PRO-MX or PRO-FXT. Serious towing work is better paired with a PRO-DXT or PRO-DX.
