So, you want to know more about 125cc Dirt Bikes? Need help?

Well, luckily, you’re in the best place for help. Today, you are going to learn a few things about the 125cc dirt bike including: 

  • The speed
  • The height 
  • The amount of horsepower 
  • If you are the right size and age
  • If a 125cc bike is suitable for beginners

  • Let’s dive straight into it.  

    Is a 125cc Dirt Bike Good for Beginners?

    If you’re new to riding dirt bikes, you may wonder what is the best bike for me. One that won’t injury me or, worse, put them off racing. This is something that all new riders consider, and you will be pleased to know the 125cc dirt bike will be the perfect bike for you. 

    For adults, the 125cc 4-stroke bike will offer you a good amount of power (but not too much), the right amount of comfort and the best experience whilst learning. It is an excellent bike for tall kids and smaller and lightweight adults. It offers the correct seat position needed for a comfortable ride. 

    Younger kids may need a smaller engine and may find the 125cc too powerful and too tall for them. In that case, it would be best to look at shorter bikes like a 50-80cc, so the ride is comfortable. 

    No matter what bike you go for, the most essential part of beginning to ride a dirt bike is to have the proper protective equipment.  

    How Fast Can a 125cc Dirt Bike Go?

    125cc Dirt Bikes have a top speed that ranges, depending on certain factors, from 55 to 70 miles per hour. But this can be increased by the terrain you are riding on. For example, suppose you are tearing down a track; you will go quicker than riding on really rugged terrain.  

    Other factors that can affect the top speed of your bike are:

  • The Size of the Engine: Bigger Engine = More Horsepower! 
  • Your Sprocket Gearing: These are capable of changing the performance.
  • Any Modifications You Make: By replacing stock parts, you can increase or decrease your top speed (Why would you want to decrease it?)  
  • The best way to test the speed of your personal bike is to take it to a time trial. This type of event is one of the best ways to know the top speed of your bike and have a fantastic time.

    What Age is a 125cc Dirt Bike for?

    A 125cc Dirt bike is an excellent option for a large range of ages. If you are a kid moving up from a lower class of engine or an adult looking to learn, the 125cc bike will offer good performance and racing for all. 

    Younger kids moving from 50cc may want to try an 80ccc bike before moving onto 125cc, as the jump may be too big for some. Never put a kid into a situation that will terrify them as this will put them off for life – nobody wants this. 

    For adults, the 125cc is perfect for learning the ropes and finding the limit of your ability. You also may feel the lower seat offers a better riding experience for you. However, keep in mind that if you are stocky, you may find that the 125cc bike doesn’t offer enough power to race to the best of your abilities.  

    Try them out though, you will never know unless you try. 

    How Fast Does a 125cc 2 Stroke Go?

    The maximum speed of a 2 Stroke is around 70 miles per hour, much faster than the 4 strokes, in which the max speed is around 50. Of course, this will depend on which model you purchase, as not all of them have the same top speed. The average speed of 70mph is taken from a wide selection of the different models. 

    If you need to know the top speed of the specific bike you are looking at, ask the retailer or research that model online and look at the specs.  

    2-strokes being a lot faster than 4-strokes (when comparing similar size models) means that they are perfect to race with. This fact may be something you want to keep in mind when looking to purchase a dirt bike. 

    It really all depends on what you, as a buyer, are looking for and what you want to get out of your dirt bike experience.

    How Much Horsepower Does a 125cc Have?

    Some Dirt Bikes with an engine capacity of 125cc tend to have horsepower ranging between 33hp and 36hp, with revolutions per minute (rpm) of around 13,000. The engines feature a single piston with 2 cycles per stroke.

    A four-stroke engine completes four different, separate strokes whilst the crank handle turns. The term “stroke” refers to the full travel of each piston in the cylinder – this can be in either direction. They are:

    • Intake:The piston pulls the Air-fuel mixture into the cylinder.
    • Compression: Air-fuel mixture is compressed by the piston to prepare for the ignition. 
    • Combustion:The mechanical work is produced here – the engine turns the crankshaft. 
    • Exhaust:Air-fuel mixture is expelled through the exhaust valve. 

    In terms of Dirt Bikes, horsepower refers to how much force the bike puts down with the rate at which the same force is applied. Thus, horsepower is a result of rotations per minute combined with torque. 

    A general formula you can use isHorsepower = Torque x RPM.

    How Tall Should You Be to Ride a 125cc Dirt Bike?

    Your height is a big part of choosing the right size Dirt Bike. For 125cc bikes, the height of your child (or whoever is riding) should be around 5 foot 5 to 5 foot 11 (about age 12-15 years old). These are approximate values, and the best way to test is in person. 

    When looking for a Dirt Bike, there are three things you should consider: 

  • Safety: To keep the rider safe and well whilst racing 
  • Height: To make the riding experience fun and fulfilling 
  • Comfort: To make the experience comfortable (especially over rough ground). 
  • Getting the right bike for the correct height isn’t just about the most adrenaline-filled ride but also about safety. Safety should be your number one thought when buying a dirt bike. We want them to race, have a fantastic time, and go away safe – ready to race another day. 

    What is the Height of a 125cc Dirt Bike?

    The height of a dirt bike ranges massively. You can find shorter bikes with a seat height of 20 inches to taller bikes with a seat height of 38 inches. This is all depending on the bike manufacturer and how the suspension is currently set up as this is an area that can be adjusted. 

    The best way to see if the bike you are looking at is the correct height is to physically get on one and test it. By actually sitting on the bike, you are saving yourself a lot of hassle in the future trying to adjust the seat to become more comfortable for the rider.
