A 125cc dirt bike is a motorcycle that is designed for off-road riding. These bikes typically have larger engines than other types of motorcycles, which allows them to achieve higher speeds
When it comes to dirt bikes, one of the most common questions is, How fast does a 125cc dirt bike go? The answer to that question is not as simple as it may seem.
There are a lot of factors that can affect the top speed of a 125cc dirt bike, such as the weight of the rider, the terrain, and the type of bike.
How fast does a 125cc dirt bike go?
Generally speaking, a 125cc dirt bike will have a top speed somewhere between 50 and 70 miles per hour. However, there are some bikes that are capable of reaching speeds in excess of 100 miles per hour.
Factors That Add to the Speed of 125cc Dirt Bike
It is often said that “there’s no replacement for displacement” and this is especially true when it comes to dirt bikes. Larger engine size will always be faster than a smaller one, all else being equal. But there are other factors that can affect the speed of a dirt bike which we have listed below.
1. 2 stroke VS 4 stroke
The type of engine is one of the most important factors in determining the speed of a dirt bike. A 2-stroke engine is typically much faster than a 4-stroke engine of the same size. This is because a 2-stroke engine produces twice as much power with each revolution of the crankshaft as a 4-stroke engine.
The weight of the bike is also a factor. A heavier bike will be harder to accelerate, but once it’s up to speed, it will take more effort to slow down.
The gearing of a dirt bike can also affect its top speed. A bike with taller gears (higher numbers) will be able to go faster, but it will be harder to get it up to speed. A bike with shorter gears (lower numbers) will be easier to get up to speed, but it won’t be able to go as fast.
Finally, the rider’s skill level can make a big difference in the top speed of a dirt bike. A more experienced rider will be able to get more out of the bike in terms of both acceleration and top speed.
3 Tips to Make Your 125cc Dirt Bike go Faster
If you own a 125cc dirt bike, you may be wondering how you can make it go faster. While there are many aftermarket parts that can help increase speed, there are also some simple tips that you can follow to get more speed out of your bike. Here are a few simple ways that can help you speed up your bike without making any major modifications.
1. Install Exhaust
One of the most effective ways to make your 125cc bike go faster is to install a performance exhaust system. This will help your bike breathe better and allow the engine to rev up more quickly.
2. Fuel change
You can also try using a higher-octane fuel in your bike as it helps the engine run cooler and therefore make it more powerful. Just be sure to consult your owner’s manual before making any changes to your bike’s fuel system.
One of the easiest ways to make your 125cc bike go faster is to simply keep it well-maintained. Make sure to regularly check your bike’s tires, chain, and other moving parts to ensure they’re in good condition.
Regular maintenance will not only help your bike run better, but it will also help prevent breakdowns and other problems that could slow you down.
A clean bike is a fast bike, so make sure to clean your bike on a regular basis. This includes washing the bike, as well as cleaning the chain and other moving parts. A clean bike will run more efficiently and will be less likely to experience problems.
Follow the above tips and tricks, you’ll be sure to see a difference in the performance of your 125cc bike. Just be sure to ride safely and always wear proper safety gear.
As noted above the average 125cc dirt bike will travel between 60-70 miles per hour. However, there are many factors that affect the speed of a dirt bike such as the weight of the rider, the terrain, and the weather conditions.
