Dirt Bikes for an 8 Year-Old Kid: A Complete Guide


Dirt bike riding can be enjoyed as early as eight years old. It’s all about selecting the proper dirt bike model that matches their physical features to ensure their safety and comfort.

You can pick a good dirt bike for an 8-year-old by checking the correct seat height and proper engine size. The best dirt bikes for an 8-year-old include Razor MX350 Dirt Rocket Electric Motocross Bike, XtremePowerUS Mini Pocket Motorcycle, and XtremePowerUS Mini Pocket Motorcycle.

How To Know The Correct Seat Height

There are many different dirt bike models for kids. Each model may vary in terms of seat height and wheel size so there’s no fixed recommendation for all eight-year-olds. The best you can do is bring your child to the bike shop and have him try out a couple of models.

Check his feet. The feet should neither be flat on the ground nor tiptoes. Being flat-footed means that their knees will bend and the seat is too low for them, hence making balancing difficult. This means they can’t grip the gas tank and it will make them sit too far back which is tricky when going up a hill. Similarly, being on their toes means the seat height is too high. This will make it challenging for them to maintain an upright posture when they can’t stabilize themselves. For a more detailed guide, refer to the chart below:

5’ 2″ (157cm) – 31 to 35″ seat height

5’ 4″ (162cm) – 33 to 36″ seat height

5’ 6″ (167cm) – 34 to 37″ seat height

5’ 8″ (172cm) – 34 to 38″ seat height

5’ 10” (178cm) – 35 to 39″ seat height

6′ (182cm) or taller – 37.5″ or taller seat height

Get The Proper Engine Size

It’s important to start small when teaching your child how to ride a dirt bike. He may start with a 50cc engine which is very manageable for short kids. After he becomes familiar with the basics of riding a dirt bike like maintaining balance and how to conquer rough terrains, he can proceed to a more powerful engine. It’s recommended to try out 110cc engines for eight-year-olds. 110cc bikes have the correct seat height that will suit eight-year-olds. The power is also challenging at first but becomes gradually manageable after sufficient practice sessions.
