How to Increase Top Speed of 125cc ATV?
There are several ways to increase the top speed of a bike which we will discuss below:
1. Changing Tire Dimension:
Big tires have large circumstances. It means the tire travels farther per revolution, effectively increasing the bike’s top speed.
You should install a clutch kit if you wish to increase the tire diameter by more than a couple of inches. If you do not attempt this step, you might lose a lot of power and may face belt slipping and burning belts issues.
2. Changing The Gearbox Gearing Ratio:
You can change one of the sprockets to increase the top speed. Bile holds a gearbox with sprockets and chains and commonly helps reduce the top speed and improves acceleration by installing a smaller sprocket.
3. Installing a Racing Clutch:
You can choose to install a racing clutch that uses different dimensions of clutch sheaves. It can alter the bike’s top speed according to your desires and needs.
4. Improving the Engine Power Output:
You can improve the top speed of ATV by increasing the power output of the bike’s engine.
5. Removing the Speed Limiter:
You should install a speed limiter if you desire to improve top speed, but be aware of yourself and don’t break or void the law regarding this.
You can reprogram the bike to disable the limiter if your bike has an electronic speed limiter. Mechanical speed limiters can be removed easily as they can be slightly disassembled and can remove the part which can limit your throttle.
6. Changing the Gear Ratio:
It is easy to alter the top speed if your bike has an open sprocket and chain. A higher top speed can be attained after increasing the size of the front sprocket and reducing the size of the rear sprocket.
You can tweak the gearing ratio to find out the optimal setup for each track into quad racing. Higher top speeds are required for the tracks having long stretches and at the expense of higher top speeds.
7. Reflashing the ECU:
Most bikes have an electronic speed limiter which prevents the riders from attempting speeds at a much higher pace. It has been reported that people have reached speeds in the range of 100mph after installing the flash of new software to their bikes’ ECU.
The limiters installed on Polaris Scrambler XP 1000 have shown a speed of about 80mph. The Scrambler XP 850 has a higher stock top speed with a limiter set at 83 mph.
Engine Sizes and ATVs:
Engine size is the amount of cc mentioned along with the name and type of each ATV. cc is cubic centimetres and is the cylinder’s volume. If we talk about 125cc ATV, it holds a cylinder volume of 125 cubic centimetres.

Weight Holding Capacity of 125cc ATV:
The right size engine depends on how much weight a quad can hold, and the majority of the people forget about this thing during their search.
Adult-sized ATVs can carry up to 250 pounds of cargo, and the maximum load capacity of 125cc ATVs is 132 pounds.

Power of 125cc ATV:
This type of ATV is considered a moderately powerful ATV and holds a general speed of 40MPH. But it is guaranteed that you will feel speed and power when you go on full throttle. 125CC engine size is considered best for the older teens and adults in the beginning stage of operating ATVs.
125cc is equipped with many safety features such as a remote kill switch, an electric start, and flexible tire size.
The 125cc engine size models having four-by-four tractions are more expensive, and you can climb at any hill through muddy roads without any single problem.
