Finding the perfect dirt bike can be tricky—especially if you're new to the sport or buying for a young rider. One of the most important factors to consider is the right dirt bike size for your age and height. Whether you're a kid looking for your first ride or an adult ready to hit the trails, getting the right fit ensures safety, comfort, and better control.

At Arlington PowerSports, we offer a wide variety of dirt bikes for all ages and skill levels. Here’s a helpful guide to help you select the right dirt bike size based on your height, age, and riding experience—plus a few great models from our collection to get you started.

Why Dirt Bike Size Matters

Choosing a dirt bike that fits your body is not just about comfort—it's about riding safely and confidently. A bike that’s too tall or too heavy can be intimidating or dangerous, especially for beginners. On the other hand, a bike that's too small can limit your control, performance, and growth as a rider.

Key factors to consider:

• Seat Height

• Engine Size (cc)

• Weight and Handling

• Rider’s Age and Experience Level

How to Check the Right Seat Height

Here’s a simple test to check if a dirt bike is the right size:

1. Sit on the bike with both hands on the handlebars.

2. Your feet should touch the ground on the balls of your feet (not flat-footed).

3. You should feel balanced—not tip-toeing or overly bent knees.

If you're shopping online and unsure about seat height, just check the specs listed on each product page at ArlingtonPowerSports.com or contact us for guidance.

Final Tips Before You Buy

• Test ride if possible (visit our Arlington store!)

• Choose a bike with a warranty and easy-to-find parts

• Think long-term: Buy a bike they can grow into, not out of in 6 months

• Prioritize safety gear like helmets, gloves, and boots
