As the highest performance model in the line of Kawasaki Brute Force ATVs, you would expect the Brute Force 750 to be able to move.
But as this model is not technically a sport ATV, can it actually hang with the fastest ATVs in the industry?
This guide will review the Kawasaki Brute Force 750 top speed and several ways to maximize it, along with how it stacks up against the other Brute Force models.
You can also check out where the Brute Force models land on the list of best ATVs for the money and comparing their speeds.
Kawasaki Brute Force 750 Top Speed
Powered by a 749 cc V-twin engine with around 50 horsepower, the Kawasaki Brute Force top speed is 74 to 75 mph.
This top speed is specific to the 2015 and later models, as models manufactured before 2015 may only reach speeds up to 71 mph.
It is speculated that the 2015+ models are slightly more responsive due to a new fuel system, hence the ability to reach higher speeds.
While this top speed is impressive, the acceleration is good as well. Loaded with low end torque, the Brute Force 750 can go from 0-55 MPH in a matter of 8-10 seconds.
This low end torque gives the quad plenty of towing/hauling power as well, with a towing capacity of up to 1,250 lbs.
How Does It Compare?
How does the Brute Force 750 stack up with its fellow Kawasaki Brute Force models in terms of speed?
Kawasaki Brute Force 650 Top Speed
Just a slight step down from the Brute Force 750 is the 650. The Kawasaki Brute Force 650 is powered by a 633 cc V-Twin engine with around 47 horsepower and can reach a top speed of 69 to 70 mph.
Kawasaki Brute Force 300 Top Speed
The Brute Force 300 is not technically a Kawasaki, but it sure moves like one.
Powered by a 271 cc single-cylinder engine with around 22 horsepower, the Kawasaki Brute Force 300 top speed is 50-52 mph.
Factoring in the difference in engine displacement and horsepower, this top speed is pretty impressive.
Increasing The Brute Force 750 Top Speed
For owners who want to make their Brute Force 750 a good bit faster, there are several modifications that can be made. And these modifications usually result in added horsepower and better overall performance as well.
Upgrade The Air Intake
Consisting of the airbox and air filter, the air intake system funnels air into the engine and ensures that air is clean.
By upgrading the air intake, you’ll maximize the amount of airflow able to make its way to the engine so that your ATV runs better.
But this added airflow into the engine means there will be added airflow that needs to exit once used up, which is where upgrading the exhaust system comes into play.
Upgrade The Exhaust
By upgrading the exhaust, you’ll maximize the amount of exhaust fumes that can escape the engine once used up.
This combination of an upgraded intake and exhaust system will result in more air in and out, which results in the ability to feed more fuel to the engine, which results in the engine being able to generate more horsepower, torque, and speed.
A few of the highly recommended aftermarket exhaust systems for the Brute Force 750 are Empire Exhaust, HMF Exhaust, and EVO Exhaust.
Have the ECU Tuned
When upgrading the air intake and exhaust systems, it’s especially important to have your Electronic Control Unit tuned as well.
An aftermarket tuning device will monitor the air to fuel ratio and calculate the correct fuel adjustments needed to achieve optimal proportions. This will ensure the upgraded exhaust system gets the proper amount of fuel needed.
This tuning of the ECU will result in improved throttle response and an overall increase in performance by ensuring the optimal air to fuel ratio at each throttle position and RPM level.
It will also reset your radiator fan to trigger at a lower temperature to help prevent the Brute Force 750 overheating problem that affects these models.
Break-In Period Determines Top Speed
For brand new Kawasaki Brute Force 750’s, there is a strongly recommended break-in period that owners should comply with. While the Brute Force 750 owner’s manual cites a ten-hour break-in period, 25 hours is a safer bet.
During the first 25 hours of operation, the various parts of the engine wear and polish themselves to their correct operating clearances, so it is important to avoid excessive engine heat. This includes avoiding continuous operation above half throttle for the first ten hours of use and avoiding continuous operation above ¾ throttle from 10 to 25 hours.
While the owner’s manual states that momentary full-throttle operation during the break-in period should not harm the engine, it should be noted that the advertised top speed will likely be unreachable in these first 25 hours of use either way.
Properly breaking in a new Kawasaki Brute Force 750 is essential to both the engine and drive components in eventually reaching peak performance and the vehicle being able to achieve the top speed of 74 to 75 mph.

Brute Force 750 Not Reaching Top Speed
If your Brute Force 750 was properly broken in but fails to reach the top speed of either 71 mph or 74 to 75 mph depending upon the year of your model, there are a few ways to attempt to correct this.
Run a high octane gas in your Brute Force 750, preferably 91 or 93 octane. A higher octane gas will result in higher performance and speed in these models. You will absolutely be able to tell the difference in the way your quad runs on high vs. low octane fuel.
Ensure the tires are fully inflated as underinflation leads to less speed. Per the owner’s manual, the recommended tire pressure for the Brute Force 750 stock tires is 5 PSI in both the front and rear.
Check the drive belt and ensure it is not old and/or loose. This could be preventing your quad from reaching top speeds. Signs it may be time to replace this belt are the vehicle snapping forward when accelerating rather than accelerating smoothly as intended, or rough acceleration in general. While a belt check indicator on the dash should provide a notification when a belt change is required, going ahead with it if experiencing the symptoms above is a best practice as ensuring the drive belt is fresh and tight should have a positive impact on the top speed of the vehicle.
Check the spark plugs. If the spark plugs are worn or fouled, they may not be igniting fuel in the engine at the proper rate which can result in lower achievable speed and acceleration. If necessary, replace them with a high-performance iridium spark plug.
Conclusion
The Kawasaki Brute Force 750 is the fastest of the Brute Force models, offering impressive straightaway speed and acceleration.
With a top speed of between 71 to 75 mph depending on the year of the model, it’s not quite as fast as some of the sportier ATV models, but definitely holds its own in the speed department.
