How Fast Does a 125cc Motorcycle Go?

One of the most common questions people ask when looking at a motorcycle is the maximum speeds it can reach. Without a doubt, a 125cc engine is small for a motorcycle and will limit its acceleration and top speed significantly.

The maximum speeds that most 125cc motorcycles will reach is between 110 and 130 mph (177 to 210 km / h), this depends a lot on the type of motorcycle. Most sports motorcycles that are 125cc were closer to speeds 130 mph top speed and the other types were closer to the 110 mph mark.

So as you have seen, 125cc motorcycles are really not as slow as most people think. They can reach relatively high speeds that will satisfy any beginner rider. The good thing is that they are very safe and cheap, you the perfect choice for beginner riders.

You want to know more about the maximum speeds of 125cc motorcycles and how You can reach higher speeds, the factors that affect your motorcycle’s speeds, and the islands 125cc motorcycles are right for you, so keep reading.

What are the factors affecting 125cc motorcycle speed?

Level of wind resistance

Maybe the factor that most affects the maximum speeds you can reach with a motorcycle Your 125cc is the level of wind resistance that your motorcycle has, while there are models that have more wind protection and there are models that have no wind protection at all.

The wind really slows down your motorcycle while riding, and there are even riders who, if most were beginner and inexperienced riders who had a tough to impossible ride. In strong winds and not only that, it isn’t easy when riding in strong winds. Your motorcycle speed will decrease significantly, so you must make sure that you had wind protection on the motorcycle.

But do not worry, your motorcycle does not have a wind-facing system installed, so you can always try to install it yourself.

Advanced motorcycles compared to low motorcycles

The sad truth is that motorcycles at higher prices were significantly faster than cheap motorcycles, and there are lots of parameters and differences between cheap and expensive. They are also the smallest, while motorcycle companies add more features to their expensive models that improve their performance, so you will always know that a more expensive motorcycle will give you more value.


Weight is super important and influential when it comes to reaching maximum speeds with Your motorcycle. The weight you weigh will affect the maximum speed you can reach and the weight of your motorcycle, which in most cases will affect the speeds even more.

So if you do not, believe me, I will give you an example you will compete in a race against a rider. You have the same type of motorcycle, but you weigh 120 pounds, and it weighs 90 pounds, so be sure that your opponent, who weighs 30 pounds, is faster than you, and chances are you will win and reach much higher speeds than you.

Number of cylinders

In my opinion, the factor that most affects your motorcycle speed is, without a doubt a number The of cylinders that are inside your motorcycle while the purpose of the cylinders is to compress and burn the fuel to turn energy into heat, which greatly affects the maximum speeds you can reach while riding.

  • In general, there are 3 types of cylinders. The first type is cylinder 1, which you need less Take care when it comes to 125cc motorcycles since only 1-cylinder SUVs are available.
  • The second type you need to know about is 2 cylinders in all motorcycles with engines below 500 cc, which means that most 125cc motorcycles had 2 cylinders.
  • And the third type is 4 cylinders that are only inside motorcycles with engine volumes of over 500cc.

2-stroke engines versus 4-stroke engines

Every 125cc motorcycle has two types of engines or 2 beats or 4 beats, each of which has different features.

2-stroke engines

2-stroke engines are very lightweight and consume as much fuel and oil as you will need to Add to it often. In contrast, these engines are super powerful and much faster than 4-stroke engines, but the disadvantage of 2-stroke engines is that their lives are quite short and destroyed relatively quickly. Hence, it is important to take this into account.


  • Very fast and powerful
  • Lightweight


  • Require a lot of maintenance
  • Short life

For whom it is recommended – recommended for advanced riders

4-stroke engines

4-stroke engines are the complete opposite of 2-stroke engines, while 4-stroke engines are Will require significantly less maintenance. Their longer life is heavier and much slower than 2-stroke engines, making you perfect for beginner riders.


  • Require less maintenance
  • long life


  • slow
  • Heavy

For whom it is recommended – recommended for beginner riders

As you have seen you want to get the highest speeds when riding so 2 stroke engines were more suitable for you, but on the other hand, you want to be more Sure, and you are a beginner rider so I will more recommend you a 4 stroke engine that will suit you better.

Riding skills

At the end of the day, you also had the fastest and most advanced motorcycle on the market for as long as possible You do not have enough skill and experience when riding a motorcycle. Hence, chances are you will not be able to reach a quarter of a day that a fast motorcycle has to offer, so this is why it is important that you first get a motorcycle that suits your level and then valid for faster motorcycles.

How to get the highest speeds from a 125cc motorcycle?

The speeds that a 125cc motorcycle can reach do not satisfy you, so do not worry Because the truth is that there are some things you can do to successfully reach the highest speeds while riding.

  • Lose Weight – The best and most effective way you can lower your motorcycle load and reach higher speeds is, without a doubt, your weight loss, while there are 2 main ways you can lower it. Your weight is through diet and the second way is to use lighter protective equipment while taking into account that lighter protective equipment will cost you more money, but it is worth it.
  • Do not ride with a full fuel tank – your fuel tank is a very significant part of your motorcycle that adds a lot of weight and load to your motorcycle, which greatly slows you down when riding. Hence, the best thing you can do is make sure you do not ride with a fuel tank Full and instead ride with a half-full fuel tank, which will give you already a few pounds less when riding.
  • Clean the air filter – Your air filter may be a small part of your motorcycle. Still, it is among the most important and significant parts, and it greatly affects the speeds Of the motorcycle, so you must make sure to clean the air filter after each ride so that the engine can work properly.
  • Install a wind protection system – you do not have a wind protection system. I am very Recommended that you install it so that you can deal with the wind while riding better and more efficiently, allowing you to reach higher speeds.

For who 125cc motorcycles are intended?
