What Is A Dirt Bike?
Today, the bike has become one of the most popular vehicles in the world due to its versatility and environmental friendliness. There are many different types of bikes on the market such as street bikes, gravel bikes, mountain bikes, hybrid bikes. Each type has a unique function to cater to the diverse riding needs of bikers.
If you are adventurous and want to explore the most rugged roads, there’s no reason to turn down a dirt bike. A dirt bike looks like a motorcycle but they are actually not the same thing.
Besides being both two-wheeled vehicles, dirt bikes are designed with completely different characteristics and purposes from motorcycles. You can easily distinguish an off-road bike from a motorbike by looking at five outstanding features including the tire, size, frame, seat, and suspension.
How important is it to choose the right dirt bike size?
Selecting the right dirt bike size is very significant. Not only is it a smart way to spend money to satisfy your riding hobby, but above all, it is also a necessity to protect yourself on the road.
Imagine what if you were sitting on a dirt bike that was too tall with a powerful engine? You might be uncomfortable along the way or more seriously, you could lose control of your vehicle. No one wants that to happen. Thus, before buying a dirt bike, don’t forget to measure your weight and height as well as consider your riding level to find out the best size for your own.
How can you look up your dirt bike size?
The first step to choose the right dirt bike size is measuring its physical size and engine size.
The physical size of a dirt bike is also known as the seat’s height. Depending on your height and riding posture, you can get a suitable position when sitting on this bike.
The engine size is rated in “CC” units or cubic centimeters. The bigger the CC number is, the higher power you will get. In general, experts will choose the big CC engine since it brings them a sense of conquest and is ideal for performing tricks. In terms of novices, smaller engines might be the better choice.
The next step you should do to select a suitable size for your dirt bike is considering some factors relating to your body and driving skill.
You need to pick a dirt bike that has the seat height matching your overall height. For the most accurate experience, I highly recommend you to actually sit on the bike.
If you don’t know what is the suitable dirt bike physical size, these tips might be very beneficial. In case you could stand on a dirt bike with your foot completely on the surface, this bike is too low for you. On the other hand, if you could not feel the balance on your foot when standing on a dirt bike, this one is also not for you.
In addition, your weight plays an important role in picking the right bike size. You should choose the volume of suspension and the dimension of an engine by weight. For example, riders weighing 150lbs and 225lbs will need two different dirt bike sizes. The higher your weight is, the more powerful the engine you should get.
However, a dirt bike size calculator just made by height and weight is not enough. You have to choose a dirt bike depending on your experience level. In other words, when you sit on a dirt bike, you have to make sure that you can handle it easily. If you are a novice, the low CC-rating is more suitable than the high ones. In general, dirt bikes with 250CC or lower are recommended.
What are dirt bike sizes for 4 – 6 year old?
For small kids, a dirt bike with a low seat height and a small engine is the most ideal option. The best dirt bike size for 6 year old is around 18.7 inches seat height. With this size range, your kids could have a comfortable posture and keep the balance when riding. Also, this size would fit smaller kids like 4 year old and 5 year old.
Since children of these ages are just getting started with this type of bike so they could not handle too much power. A dirt bike equipped with a 50CC engine is suitable for them.
Additionally, for these very young riders, their parent’s supervision is necessary. Some dirt bikes with added safety features such as training wheels, throttle limit, an automatic transmission will be more useful for your kids.
What are dirt bike sizes for 7 – 9 year old?
For children aged 7 years old, 21 inches dirt bikes might be a great choice for their height and weight. At this size, they could sit comfortably on this bike and have an upright posture.
The dirt bike size for 8 year old and the dirt bike size for 9 year old are a little bit higher. You could pick a model with a seat height range from 24 inches to 28 inches. Depending on the specific height of riders, the dirt bike size could be varied.
In terms of engine, the most suitable start point for this age range is from 70cc to 90cc. You could decide what is the best deal for your kids if you know clearly their dirt bike experience level.
What are dirt bike sizes for 10 – 12 year old?
If your 10 year old or 11 year old kids want to ride a dirt bike, what size you choose? In general, the dirt bike size for 10 year old will start from 26 inches. Since each rider’s height is different, you need to know exactly your child’s measurements to pick the best seat height.
If you are searching the dirt bike size for 11 year old riders, you could consider 27 – 29 inches ones. For 12 year old children, 30 – 31 inches seat height is an ideal consideration. Make sure that when your kid stands on the dirt bike, his feet could touch the ground.
The most appropriate number of CC you should get for this age range is under 125cc. This type of engine is not too strong for children’s movements. If your child is a newbie, you could choose a 90cc or 110cc engine for more security.
What are dirt bike sizes for 13 – 15 year old?
Once you head over to the dirt bike size for 13 year old, I will highly recommend you to get a 30 – 32 inches seat height since this range could match the typical height of your 13 year old kid. If your children are taller and heavier than the general range, they could try out 33 – 34 inches in size.
In case you want to choose a dirt bike size for 14 year old, 33 – 35 inches seat height is a great choice. Meanwhile, the best dirt bike size for 15 year old is between 35 inches and 37 inches.
For 13 to 15 year old riders, you should choose the engine with a CC number that is higher than 110CC since they need a more powerful dirt bike. The 125CC and 150CC models are outstanding options. If your kid has been familiar with dirt bikes for a long time, he can also try the 250CC engine models.
What are dirt bike sizes for adults?
If you are looking for a dirt bike for adults, the seat height between 31 inches and 37.5 inches is the way to go. Based on your specific height and weight, you could choose the right physical dirt bike size.
If your body is shorter and smaller than the general body type, the recommended seat height is from 31 inches to 33 inches. For those who are 5’4” and 5’6” in height, let’s go to the dirt bike with seat height around 33 – 35 inches. In case you are taller than 5’8”, then I will suggest you move to 35 – 37 inches dirt bike size.
In addition, your weight will decide which type of engine you need. For lightweight riders, 250CC or 350CC could offer the best riding experience. They could run smoothly but still strong enough for cool tricks. If you are heavier in weight, a more powerful engine like 450CC and 500CC might serve you better.
However, don’t forget to consider your riding skill. Even when you weigh over 300lbs but you are a newbie, 450CC might be overwhelming for you. Work out one step at a time and start with lighter engines like 350CC.
How to adjust the dirt bike height?
If you are reading this article after purchasing a bike that isn’t the size you expect, here are tips to help you improve its comfort.
In terms of this dirt bike is quite higher than your body size, you could lower its height by reducing the seat size. The simplest method to do is to cut the foam inside the saddle. It will not make a big change or reduce the comfort when you sit on this bike.
If you feel your dirt bike is too low then you should increase its height. You just have to make the foam in the seat thicker and higher by your way to fix this problem.
The Ultimate Guide To Choosing What Size Dirt Bike Do I Need
When you finish the step of choosing the right size, you have to consider other factors to buy a good dirt bike.
The first thing you should keep in mind is your budget. The cheapest version of dirt bike that you could get has the price range of $200 – $500. For a two–stroke engine dirt bike, you might spend about $2000 to purchase it. The more powerful an engine is, the higher price you have to pay.
