As CFMoto’s highest-performance utility vehicle, the UForce 1000 makes for an excellent all-around UTV with its combination of power and speed.
And adding a few of the most popular CFMoto UForce 1000 accessories will turn it into a real beast.
But even in stock condition, its V-Twin 963cc engine puts out around 79 horsepower, giving it plenty of oomph to tackle any terrain or work task.
And a comparison of the CFMoto UForce 1000 vs Can Am Defender shows these models to be neck and neck as some of the fastest UTVs you can find.
So how fast can the UForce 1000 go?
This guide will detail the CFMoto UForce 1000 top speed and why the speedometer may trick you into thinking you’re going faster than you are.
CFMoto UForce 1000 Top Speed
While the CFMoto UForce 1000 top speed will likely show 75 mph on the speedometer, this is not accurate.
The more realistic top speed of a CFMoto in stock condition is around 65 mph, which still makes it one of the fastest utility side-by-sides available.
Why is the speed inaccurate?
The speedometer displays speed based upon the tire circumference setting in the system, and a known flaw with the CFMoto 1000 is that the factory tire circumference setting is generally not accurate.
Owners should check to ensure the tire circumference is set correctly and calibrate the speedometer if not.
Tire Circumference Setting
To check your tire circumference setting, hold down the “Select” button on the left side of the digital display in the dash for a few seconds. This should send the screen from normal mode to calibration mode.
You should see a number at the bottom, which will be the circumference of the tires you are running. The problem lies in that the factory set circumference doesn’t usually match up with the size of the stock tires.
As the UForce 1000 is installed with 27-inch stock tires, the circumference number at the bottom of the display should read 84.8 inches.
However, the factory circumference is usually set at 100+ inches, aligning more closely with 31 or 32 inch tires.
This means the speedometer thinks you are riding on much bigger tires than you actually are, which inflates the speed shown on the speedometer.
While this error leads to an inaccurate speed reading, it will also lead to your odometer showing that your vehicle has traveled more miles than it actually has.
This can shorten the length of your warranty and negatively affect the resale value of the vehicle.
To fix this, owners should calibrate their speedometer. For reference, below is a graph of the correct circumference by tire size.
| Tire Size | Circumference |
| 25 inches | 78.5 inches |
| 26 inches | 81.6 inches |
| 27 inches | 84.8 inches |
| 28 inches | 87.9 inches |
| 29 inches | 91.1 inches |
| 30 inches | 94.2 inches |
| 31 inches | 97.3 inches |
| 32 inches | 100.5 inches |
| 33 inches | 103.6 inches |
Calibrating The Speedometer
To calibrate the speedometer, follow the same process described above for navigating to calibration mode by holding down the Select button on your digital display.
Once the screen moves to calibration mode, long press the Select key again until the first digit in the circumference setting begins to blink.
Long press again to get to the second digit and once flashing, short press to the correct number. Repeat this long pressing and short pressing for the remainder of the digits until you’ve input the correct circumference.
After doing this, both the speedometer and odometer should reflect more accurate readings.

Increasing The UForce 1000 Top Speed
For those looking to increase the speed of the UForce 1000, there are a couple of modifications that can be made to do just that.
Re-clocking Secondary Clutch
Owners may want to start by re-clocking the secondary clutch, which contains an adjustable spring. This spring has a number of different settings that affect the power, speed, and overall performance.
The UForce 1000 will be set at the B-1 setting out of the box. For more top end speed, owners can move to the A-1 or C-1 setting.
Doing so should help relieve the jerkiness known to occur when accelerating as well.
Add A Clutch Kit
The clutch in the UForce 1000 is known to be problematic, resulting in a jerky take-off when throttling from a stopped position.
But it can also affect the speed and power of the vehicle. Some owners report a lack of throttle response and the power fading out when climbing steep hills with two or more passengers.
There are a number of aftermarket clutch kits available that can correct these issues with the stock clutch. These clutch kits will upgrade the spring, weights, and helix of the clutch system.
RNG Performance and Main Street Cycle both offer highly recommended clutch kits for the UForce 1000, which are said to greatly increase the performance of the vehicle.
Tune The Electronic Control Unit
As a safety feature for the engine and for riders, the UForce has an electronic speed limiter in place.
Owners can delete this speed limiter by sending in their ECU to be tuned. An ECU tune will remove this speed limiter, but will also benefit your UForce in some other ways.
A tune will recalculate the vehicle’s optimal air to fuel ratios and update them within the ECU, which will give your UForce better throttle response and horsepower across all RPM levels.
This should result in more power and top speed for your vehicle.
Additionally, a tune will usually reprogram the radiator fan to engage at lower engine temps, which will help to avoid any instances of overheating.
Main Street Cycle offers a highly recommended ECU tune specific to the UForce 1000.
An ECU tune is also essential if you plan to upgrade your air intake and/or exhaust system.
Upgrade The Air Intake
The air intake system is responsible for providing the UForce’s engine with plenty of clean air so it can breathe properly.
The more air in and out of the engine, the more power and speed it will be able to generate.
By upgrading the intake components such as the airbox and air filter, you’ll increase the amount of airflow into the engine.
Both UNI Filters and K&N Filters make highly recommended intake upgrades for the UForce 1000.
Upgrade The Exhaust
The second half of increasing the air circulation to the engine is to provide an efficient escape for the increased airflow into the engine once it has been used up.
This can be achieved through an upgraded exhaust system.
An upgraded exhaust should benefit your UForce by providing more torque, horsepower, and speed throughout the RPM levels.
And let’s not forget about the enhanced growl it will provide your vehicle while riding.
Both Whiskey Bent Motorsports and RJWC Powersports offer aftermarket exhaust upgrades for the UForce 1000.

CFMoto UForce 1000 Top Speed Not Reachable
If your UForce 1000 has been properly broken in and the speedometer has been calibrated but does not seem able to reach a top speed of around 65 mph, there are some ways to overcome this.
Work Mode vs. Normal Mode
For owners of 2022+ models, there is a switch on the dash that offers both Work and Normal mode.
Normal mode is for more casual driving, so the acceleration and speed will be dampened. In Work mode, the vehicle will be able to reach its full potential in terms of acceleration, speed, and power.
Ensure your UForce is in Work mode and High gear to achieve a top speed of around 65 mph.
Bigger Tires
The UForce 1000 comes equipped with 27-inch stock tires. Replacing these with bigger aftermarket tires will increase the achievable top speed.
Many owners have made the jump to a tire somewhere in the 28-inch to 30-inch diameter range and experienced positive results.
Tire Pressure
Ensure the tires are set at the recommended tire pressure. Per the owner’s manual, the 26-inch stock tires have a recommended PSI of 14 in the front and 18 in the rear.
Drive Belt
Check the drive belt to make sure it is not worn or fitting loose. This can have a negative effect on the UForce’s top speed.
The inferior clutch can cause issues for the drive belt, so it’s important to ensure no damage has been caused by it. Making sure the drive belt fits tightly and is fresh will ensure better performance and speed.
High Octane Fuel
Running 91 or 93 octane fuel in your UForce 1000 is highly recommended. This will result in better overall engine performance and a potential higher speed, and you’ll definitely be able to tell a difference in how it runs on high vs. low octane fuel.
Check Spark Plugs
Check to ensure the spark plugs are not corroded or fouled. If inspecting them and the tips appear to be a dark gray or black color, this indicates fouling.
The spark plugs should be replaced with a high performance iridium spark plug for better engine performance.
Break-In Period & Top Speed
For owners of a brand new UForce 1000, it’s essential to adhere to the break-in period outlined in the owner’s manual to ensure your new vehicle eventually reaches its top speed and peak engine performance.
The owner’s manual states that this break-in period is the first 20 hours of operation or the first 466 miles of operation, whichever comes first.
During the break-in period, the engine components wear themselves to their proper operating clearances so it is essential to avoid excessive engine heat during this time.
Before operating the machine, owners should check the engine oil level to ensure it has been properly filled.
Upon first starting the machine, owners should also let it idle for 1-2 minutes before throttling.
To avoid much engine heat, it is highly recommended that owners avoid operating at more than ½ throttle for the first ten hours of use and ¾ throttle from between ten and twenty hours.
It’s also important to vary throttle positions and not operate the vehicle at a sustained throttle position or sustained idle for too long.
CFMoto advises against pulling or hauling any heavy loads during this time as well.
At the end of the break-in period, be sure to change the air filter and engine oil.
However, you should be checking the air filter, oil level, and coolant level periodically throughout the break-in period as well to ensure they are correct.
Failure to properly break in your UForce 1000 can result in the engine never quite reaching peak performance and your top speed suffering as a result.
Conclusion
While the CFMoto UForce 1000 top speed will likely show 75 mph on the speedometer, owners will need to calibrate it to get an accurate speed and mileage reading.
The actual top speed of a UForce 100 in stock condition is closer to 65 mph.
Owners who want to reach a higher top speed can make some modifications or ensure that certain components of the vehicle which affect the speed are in top shape.
