There is no definitive answer when it comes to finding the best size dirt bike for a 12 year old. It will depend on their individual height, weight and riding experience. However, there are some general guidelines that can help you choose the right bike for your child.

As a general rule, the smaller the bike, the easier it will be to control. This is especially important for younger or inexperienced riders. A 50cc dirt bike is usually the smallest size available and is a good choice for most 12 year olds. If your child is particularly small or has very little riding experience, you may want to consider a smaller bike such as a 40cc or even a 30cc.

Remember that your child will eventually grow out of their bike. If you think they may want to continue riding when they are older, it’s worth investing in a bike that they can grow into. A 70cc or even an 80cc dirt bike would be a good choice for most 12 year olds with an interest in motocross racing.

When choosing a dirt bike for your child, it’s also important to consider their level of experience and confidence. A more experienced rider will be able to handle a larger and more powerful bike than a beginner. If your child is new to riding, it’s best to start them off on a small and easy-to-manage bike. They can always move up to a bigger model once they have perfected their skills.

The Different Sizes of Dirt Bikes

There are many different sizes of dirt bikes. The size that is best for a 12 year old depends on the child’s height, weight, and riding experience. If the child is new to riding, a smaller bike might be best. If the child is taller or heavier, a bigger bike might be better.


The 50cc dirt bike is the smallest size available and is usually recommended for kids aged 5-8 years old. This bike will have a top speed of around 30mph. If your child is a beginner, this would be the ideal size for them to start off with as it’s not too powerful and easy to control.


The 65cc class is the smallest of the motocross bikes. These bikes are built for kids ages 6 to 9 years old (or up to about 4’10” tall). They weigh about 85 pounds, have a seat height of about 26 inches, and most have less than 10 horsepower. The smaller size and power make them easier to control than larger motorcycles.


The 85cc dirt bike is a great option for a 12 year old. It has plenty of power to tackle any terrain, but is still small and light enough to be manageable.


125cc dirt bikes are great for kids who are just starting to ride. They’re light and easy to maneuver, and they have enough power to get your child up and down the trails. If your child is serious about riding, a 125cc bike will give them the foundation they need to move up to a larger size.

Which Size is Best for a 12 Year Old?

There are many factors to consider when purchasing a dirt bike for a 12 year old. The most important factor is the size of the bike. The wrong sized bike can be dangerous and cause injuries. Another factor to consider is the skill level of the child. A beginner will not need as much power as an experienced rider.


50cc dirt bikes are perfect for kids aged 6-12 years old. This is because they are lightweight, easy to control and have low power output. 50cc dirt bikes will travel at speeds of up to 30mph, which is perfect for young riders who are still developing their skills.

If your child is aged 6-8 years old, then a 50cc dirt bike will be the perfect size for them. The 50cc engine will provide them with enough power to keep up with their friends, but not so much that they will get into trouble.

If your child is aged 9-12 years old, then they may be ready for a bigger bike. If they have outgrown their 50cc bike and they are showing signs of being ready for more power, then you could consider shifting them up to a 65cc or 85cc bike. Just be sure to start them on a smaller bike so that they can get used to the power and the weight.


At the age of 12, most kids are ready to move up to a bigger bike. They may have outgrown their 50cc starter bike, or they may be ready for more power and speed. A 65cc dirt bike is a great choice for many 12 year olds.

A 65cc dirt bike is powerful enough to keep up with traffic, but not so powerful that it will be unmanageable for a young rider. These bikes are also light enough to be easily maneuverable, yet durable enough to withstand the rigors of off-road riding.

There are a few things to keep in mind when shopping for a 65cc dirt bike. First, consider the rider’s skill level. If the rider is new to dirt biking, look for a bike with an automatic transmission and electric start. These features will make the learning process easier and less frustrating.

Also, be sure to check the weight limit on the bike. Most 65cc dirt bikes have a maximum weight capacity of around 220 pounds. If the rider is close to this limit, consider upgrading to a larger size bike.

Finally, make sure to get a good deal on your 65cc dirt bike. These bikes can be expensive, so it’s important to shop around and compare prices before making your purchase.


An 85cc dirt bike is going to be the best size for a 12 year old. The power is manageable but still enough to have some serious fun on. This is going to be a great bike for your child to learn on and develop their riding skills.


The 125cc dirt bike is the most popular choice for 12 year olds. It is the perfect size for them to learn on, but still has enough power to keep them entertained. The 125cc bike will also be big enough for them to grow into, so they won’t need to upgrade to a larger bike for a few years.


After carefully considering the options, we believe that the best dirt bike for a 12 year old is the Suzuki DR-Z125. It has just the right mix of power and features to suit a wide range of riders, and it’s also very affordable.
