How Long is a Dirt Bike?

Are you trying to figure out what size of dirt bike you will need, or are you just curious to know about the length of your dirt bike? Here are some crucial facts to know before shopping for a dirt bike.

There are many factors to consider while selecting an ideal dirt bike, but what makes it comfortable is its height and weight based on your needs. 

Let’s explore some major features of a dirt bike before you spend your money on it. After all, it doesn’t come cheap. 

Dirt Bike Length 

Are you planning to get a bike for yourself? Or are you thinking of purchasing it for your child? 

In either case, you might be wondering about the size and measurement of the dirt bike. However, you can find an answer by taking some measurements.

You can measure the length of the dirt bike from the front tire tread to the back tire thread. Here we have shared all the measurements for you. 

  • When it comes to adult bikes, the average length of the bike is 82.8 inches. 
  • For children’s bikes, the approximate length is 52.9 inches.
  • If you are buying a dirt bike for your kid who is 12 years old and 5 feet tall, then a 110cc dirt bike can be a perfect choice. It has an overall length of 52.8 inches and 24.8 inches in width.
  • Also, choosing three-speed transmission and automated clutches will make your child used to two wheels. However, it can be suitable for 15 to 18 years old as the CC models are best for handling a dirt bike.

Various Sizes of Dirt Bike

Dirt bikes come in a variety of sizes, from 20-39 inches seat heights to 20-25 inches. The size of the bike can be 20 to 25 inches for little kids, while children of 10 to 12 years old can use 26 to 30 inches seat heights. Then there comes the seat height of the middle dirt bike, which falls between 29 to 35 inches.

Some bikes feature full-size wheels (21 inches in front and 18 or 19 inches in back), but others are significantly smaller. Due to being a few inches less in height than a full-size bike, these motorbikes are considered medium or midsize bikes. 

Moreover, they make every ride easier for a short-height person.

Size of a Medium Dirt Bike

As the sizes vary from one bike to another, there isn’t a standard size of a medium dirt bike. 

We can guess by looking at regular dirt bikes that come with a seat height of around 21 to 30 inches. Even some bikes have 35 to 38 inches of seat height, which is too tall for a  person with a short height.

Seat Height and Your Height 

Your height is as important as that of a dirt bike. It is also essential for your safety and comfort. First, you need to consider your total height. By doing so, you will get the idea of choosing the suitable bike according to your width and height. 

Another thing you can do is to get on the bike and see if your feet can touch the grounds. Some people have shorter legs and longer arms, so by having a test ride, they can get the idea of riding the desired size bike.

In addition, if you are a newbie, the seat height is crucial as you want to be able to put your feet on the ground when you come to a halt. You will also gain confidence since you won’t have to worry about tipping over.

Why Should You Consider Bike Length?

While measuring the length of your bike, you need to make sure the size isn’t too big to handle. Big size bikes are heavier and are difficult to handle, so we would suggest avoiding them initially. 

Moreover, if you are an inexperienced person you should also ignore them until you have become used to heavy wheels.

Although bigger bikes look cool, they might be the wrong choice for a first-time user.


Dirt bikes are considered comfortable bikes only when they are according to your size. Their particular riding style is best suited for off-road and rugged terrain. However, big-sized dirt bikes have cool looks, but sometimes bigger ones may get you in trouble. 

Therefore, always be safe while riding on a bike and avoid too much weight and powerful bikes. You can check your height and find the best dirt bike that goes with your leg height.
