1. How to Size a Dirt Bike for a Child
Getting the right size dirt bike is not only important for your child but for anyone intending to take up dirt bike riding. According to the American Motorcyclist Association (AMA), proper bike fit enhances control and reduces the risk of accidents. A well-fitted bike ensures that the rider can confidently handle the machine. This is even more important if the person is just beginning, and this will be their first dirt bike. Here are the main reasons that a bike of the right size is beneficial to your child or anyone else.
-
Starting: Many dirt bikes still use the kickstart method to get the engine going. It is very difficult to kickstart a bike that is too big for you. Ensure the child can comfortably reach the kickstart lever.
-
Balance: If the bike is too tall for the person, they will have trouble pulling off and stopping the bike. According to research from the Motorcycle Safety Foundation (MSF), in July 2025, a bike with proper seat height allows the rider to maintain balance and control.
-
Confidence: If the person or child feels comfortable on the bike, they will have more confidence, and their ability to learn to ride and negotiate the terrain will progress at a more rapid pace. A confident rider is more likely to enjoy the experience and progress quickly.
-
Control: If the dirt bike is too big for the person, not only in physical size but also the power of the motor, then the person will struggle to control the bike and could develop a fear for the machine. Too much power can be intimidating and lead to accidents.
-
Safety: Safety should always be a top concern in dirt bike riding, especially for kids, and all the previously mentioned points could result in a compromise of the safety of the child on the bike. A properly sized bike reduces the risk of falls and injuries.
The temptation may be to buy a bike that is slightly too big for the child so that they can “grow into the bike.” This may be a good strategy when you buy your kid a pair of jeans, but not when it comes to dirt bikes!
Yes, kids do grow fast, and they will outgrow their dirt bikes, but it is not worth compromising their safety by buying too much bike for them to handle. Dirt bike riding is a growing outdoor activity, and as such, there will always be a market for second hand bikes.
Once your child outgrows the bike, sell it and put the funds towards buying a bike another size up for your kid. Visit usabikers.net for advice on buying and selling used dirt bikes.

1.1. Guidelines to Find the Right Size
The standard way to size a bike is by the person’s height and what seat height of the bike is appropriate for that particular bike.
Generally, the power of the motor will increase along with the increased height of the bike until you get to a certain seat height, where you will get a number of different sized motors in that range of bikes.
With the younger generation kids in the 3 to 7-year age group, the bike could last the child a good few years before you need to upgrade. We will cover this aspect when we discuss individual bikes.
The best way to judge the right size bike for your child is to use the following guidelines to establish a baseline size bike.
| Child Age | Child Height | Bike Seat Height | Engine Size In CC |
|---|---|---|---|
| 3 – 7 years | 2ft 7 inches to 3ft 7 inches | 17 – 21 inches | 50cc |
| 7 – 12 years | 3ft 7 inches to 4ft 7 inches | 21 – 25 inches | 50cc – 110cc |
| 12 – 14 years | 5ft to 5ft 2 inches | 31 – 35 inches | 125cc |
| 14 – 16 years | 5ft 2 inches to 5ft 8 inches | 35 – 38 inches | 125cc – 250cc |
These guidelines should help you to find the right size dirt bike for your kid, but you also need to take into account the boldness and personality of your child, especially when choosing the engine size of the bike. Some kids show no fear, and others are a little more conservative and reserved.
Let your child progress in dirt bike riding at their own pace, and don’t push them to ride a bike that is too powerful for their level. Usabikers.net encourages a safe and gradual approach to learning.

2. What Size Dirt Bike Should a 9-Year-Old Ride?
For a 9-year-old, a dirt bike with an engine size between 50cc and 110cc is typically suitable. According to the Motorcycle Industry Council (MIC), a 9-year-old rider should have a seat height that allows them to comfortably place both feet on the ground or the balls of their feet. This ensures better control and balance. You would need a 50cc-110cc bike with a wheel size of between 21 and 25-inches to cater to the height of your child.
| Attribute | Detail |
|---|---|
| Engine Size | 50cc – 110cc |
| Seat Height | 21 – 25 inches |
| Wheel Size | 21 – 25 inches |
| Rider Experience | Beginner to Intermediate |
2.1. Factors to Consider
When determining what size dirt bike for a 9 year old is best, several factors should be taken into account:
-
Height and Weight: Ensure the bike’s seat height allows the rider to comfortably reach the ground.
-
Riding Experience: Beginners should start with smaller engine sizes.
-
Confidence Level: A more confident rider may handle a slightly larger bike, but safety should always be the priority.
Usabikers.net offers personalized advice to help you evaluate these factors.
2.2. Popular Models for 9-Year-Olds
Several models are popular among 9-year-old riders:
- Yamaha PW50: A great starter bike with an adjustable throttle.
- Honda CRF50F: Reliable and easy to handle.
- KTM 50 SX: A more performance-oriented option for experienced young riders.
These bikes are designed to be manageable for young riders, with features that enhance safety and control.
3. What Age Is a PW50 For?
PW50 bikes are a great entry-level bike for the younger generation of dirt bike riders. These bikes are so popular that they come in a range of sizes. The size can be adjusted as the child grows by increasing the size of the wheels on the bike, which would make the bike a better fit for your child as they grow.
This means that a PW50 can be suitable for a child from the age of 3-years all the way to 7-years old. According to Yamaha, the PW50 is designed for riders who are just learning, with features like a fully automatic transmission and adjustable throttle stop. The popularity of these bikes also means that there is a great secondhand market for these bikes.
Another bike that fits well into this age group is the KTM50, which is also popular and has a little more of a rugged look to it than the Yamaha PW50. Visit the usabikers.net forums to discuss the best entry-level bikes.

3.1. Adjusting the PW50 for Growth
The PW50’s adjustability is a key benefit, making it a long-lasting option for young riders.
- Adjustable Throttle: Allows parents to limit the bike’s speed as the child learns.
- Seat Height Modifications: Minor adjustments can be made to the seat to accommodate growth.
- Wheel Size: Although limited, tire options can slightly alter the bike’s height.
3.2. Alternatives to the PW50
While the PW50 is a popular choice, other models cater to this age group:
- KTM 50 SX Mini: Offers higher performance and adjustability.
- Honda CRF50F: Known for its reliability and smooth power delivery.
- Suzuki DR-Z50: A user-friendly option with a low seat height.
These alternatives provide a range of options based on the rider’s skill level and preferences.
4. How Old Should Your Child Be to Ride a 250?
When you get to the bikes with the larger engines, the dynamic changes quite substantially. These bikes may only be 125 or 250cc, but they are very powerful machines that should be treated with respect and responsibility.
125cc bikes are generally more than enough for most teenage riders. Many adults ride the 125cc class motorcycles as well, which is an indication of the power of these bikes.
The 250cc is a big jump from the 125cc and is a lot of bike for a teenager to handle. This is especially true if your child is a smaller framed person and is not tall enough or does not have the physical strength to handle the bike.
It is recommended that only teenagers from the age of 16-years upward consider riding a 250cc dirt bike. According to the MSF, riders should have several years of experience on smaller bikes before moving to a 250cc. Even so, you should only consider this bike for your kid if they are tall for their age and have the experience and strength to be able to tame a 250cc dirt bike.

4.1. Progression to Larger Bikes
Graduating to a 250cc dirt bike should be a carefully considered decision based on:
- Riding Experience: Years of experience on smaller bikes.
- Physical Strength: The ability to handle the bike’s weight and power.
- Maturity: Understanding the responsibility of riding a powerful machine.
4.2. Alternatives to 250cc for Teenagers
If a 250cc is too much, consider these alternatives:
- 125cc Two-Stroke: Offers a balance of power and manageability.
- 150cc Four-Stroke: A step up from smaller bikes but less aggressive than a 250cc.
- 200cc Four-Stroke: Provides a good transition for riders with some experience.
