The CFMoto UForce 800 is a perfect UTV and you get your money’s worth. The UForce 800 has been on the market for several years now, and there are also used ATVs for sale. When you are in the market to purchase the UForce 800, you are certainly curious about its reliability and driving characteristics. That also includes the top speed.

The maximum speed of the CFMoto UForce is governed. The manufacturer claims that the CFMoto UForce 800 has a top speed of 43 mph (75 km/h), but the actual speed may vary depending on several factors.

I’ve gathered the numbers in this article from specs sheets and YouTube videos where the UForce is driven fast. We haven’t just collected theoretical data, we’ve also looked at how the UForce works in practice.

Additionally, we’ll give you 6 suggestions on how to ramp up your UForce and increase the top speed, so read on!

What Is The Top Speed Of The CFMoto UForce 800?

The top speed of the UForce 800 is set by the manufacturer at 43-45 mph. However, the UForce 800 can drive much faster because the engine certainly has the capacity for this. There are owners who achieve top speeds of 60 mph all the way up to 70 mph.

This can be reach by removing the speed limiter and by making adjustments to the engine and engine-related parts. Later in this article, 6 of these adjustments are discussed.

In addition, the UForce has a standard tire size. If other tires are fitted ex. factory, the speedometer will not display the correct speed. This is really one of CFMoto’s problems. If you want to measure the real speed, you will have to check the tire size and reset it if necessary.

The different in tyre size can give a speed deviation of up to 15%. Later in this blog, a video explains how you can change this setting.

How To Make Your UForce 800 Go Faster?

Many factors affect the top speed of your CFMoto, including horsepower, drivetrain, the weight of the occupants and cargo, the terrain and weather conditions, the altitude you ride at, and accessories on your vehicle.

If you still have a factory warranty on your UForce 800, I advise against ramping it up. Adjusting your CFMoto could void the warranty, meaning if you run into any major issues, you’ll likely have to pay for those yourself. So, first check your warranty before you make the alterations.

You can increase the power and top speed of your UForce 800 through the following:
(but remember, this is at your own risk)

1. Appropriate Size, Weight, and Pressure of Tires

Consider upgrading to larger tires in order to achieve a faster acceleration and a higher top speed. Bigger tires turn harder and go further every revolution of the wheel. Depending on the surface, tire pressure might also affect performance. Higher tire pressure is best for riding on flat, firm surfaces, but lower tire pressure is better for riding in sand or snow.

Large mud tire combinations and common wheels restrict your vehicle’s speed. You could consider getting lightweight aluminum rims and high-performance tires to make your UForce quicker. Pick the appropriate tire size for your work or hobby.

Factory Set Tyre Size Is Sometimes Not Accurate

It appears that the speed reading is incorrect on some UForce 800 ATVs. There are large differences in speed due to this. Although you may believe that you are driving very fast, there may be a deviation of 15%

This deviation is due to the tyre size (circumference), which is factory-set. The speed will be different if a different tire size is installed on your UForce 800. The speedometer displays a speed based on the tire circumferences.

You should watch the next video if you want to check which tyre size is factory set or if you intend to change the size. It explains step-by-step what to do.

2. Tweaking The ECU

The UForce 800 is equipped with an Engine Control Unit (ECU). Various engine functions, such as fuel injection, ignition timing, and throttle response, are controlled by the ECU.

You can change the ECU settings to improve the top speed. Modifying the ECU settings may void the warranty and may not be legal in some areas. Also, any changes to the ECU should be done carefully and with the right knowledge and tools.

You can use a diagnostic tool to change the UForce 800s ECU settings. Using the diagnostic tool, you can connect to the ECU and change the settings, such as the fuel map and ignition timing, to make the engine run better.

Here are the general steps to modify the ECU settings:

  1. Obtain a diagnostic tool that is compatible with the CFMoto CForce 800s ECU.
  2. Connect the diagnostic tool to the vehicle’s ECU according to the manufacturer’s instructions.
  3. Use the diagnostic tool to access the ECU’s settings and modify the parameters related to fuel mapping, ignition timing, and other performance-related settings.
  4. Save the new settings to the ECU and test the vehicle’s performance to see the improvements.

3. Choice Better Fuel

If you want to make your UForce faster and more powerful, switch to a higher-octane fuel. Since fuel with a higher octane level burns more thoroughly, your engine will run better. Furthermore, it offers superior fuel efficiency and protects your vehicle because the mechanical parts of the fuel system corrode less frequently.

A noticeable performance boost ought to be seen. Higher-octane fuel costs more than regular fuel, but it is exhilarating to press the accelerator. The octane level is often raised by rig owners because they prefer a healthier boost than what is offered at a gas station. Put a little fuel into the gas tank and shake your Commander back and forth to mix it thoroughly. You can also mix the fuel in a gas can before adding it to the gas tank to make sure your measurements are correct.

4. Working on the Gear Ratio

Gear reductions are incorporated into everything from the engine to the gearbox to the wheels. The gear ratios in the UForce 800’s drivetrain determine its torque and speed. Performance issues due to drivetrain inefficiencies can arise, and it is more difficult to characterize.

When designing gear reductions, the purpose of the machine is taken into account. On faster machines, smaller gear reductions are used to increase the top speed. The more significant gear reductions on working machines provide additional torque for pulling and hauling. The UForce and all of its variations fall somewhere in the middle.

Swap out your front or back sprockets to alter the gear ratio. Most owners gear down, which entails installing a larger rear sprocket to increase acceleration but decrease top speed. Decide whether to increase acceleration or peak speed. A clutch kit and sprocket may produce a significant improvement.

5. Install High-Flow Air Filters 

Your air filter needs to be checked and cleaned regularly. A dirty filter stops air from getting to the combustion chamber, which makes your engine suffocate while you drive. The replacement of the stock air filter with a high-flow filter can improve engine performance. The richer air-fuel mixture results in increased power, and an improved intake allows for more airflow to the engine. It is one of the most straightforward ways to increase the performance of your engine.

K&N is a trusted and industry-leading air filter manufacturer for almost all Powersports and automotive applications. You can get K&N high-flow air filters for between $15 and $125.

6. Upgrade The Exhaust

The UForce 800 exhaust system upgrade is a popular method for improving the UTV’s performance. It enables the engine to exhaust more, so more air is drawn in. This system performs better with a high-flow air intake setup.

A performance slip-on muffler is a viable alternative to replacing the exhaust system when time or financial constraints exist. It is the most common technique because it allows you to replace your stock muffler with a lightweight one. Also, slip-on mufflers have cores that have higher exhaust flow rates than standard systems with a lot of baffles.

The slip-on muffler delivers more power, but it is still considerably less than what you would get with a full-performance exhaust system. Combine a high-flow intake system with a slip-on or full exhaust system to make the engine more powerful.

Performance exhaust systems typically gradually increase in size or diameter over stock exhaust systems, frequently looking like cones. The cone shape lets more air get to the engine, and the richer air-fuel mixture makes a big power boost. CFMoto UForce 800 aftermarket exhaust systems range from around $400 to $900.
