Children and safety

A size chart ensures that you pick the right height and perfect dirt bike with reliable engine power and size. However, if interpreted with the rider’s needs and requirements in mind, a size chart benefits the rider more with its recommendations.

In this guide, we intend to highlight the significance of the dirt bike size calculator or chart and help you pick the perfect dirt bike and with the regulated motor capacity for your children as well as yours.

Manufacturers design 50cc capacity engines for kids aged between five and seven years. You can also use the information as a standard for choosing the perfect dirt bike size for any other rider.

Before allowing your kid to start racing on a dirt bike, ensure that you first train them appropriately on the importance of safety gear and how to stack up when riding.

Even with the right safety gear, children will hardly learn to ride their bikes properly if the bike sizes do not suit their needs.

Make sure you find the engine capacity recommended for your child’s age. A powerful engine can pose numerous riding challenges and high safety risk for a kid with zero riding experience.

Multiple brands by designers suit different riders’ tastes and preferences because of their customer-tailored specifications.

Besides, the bikes come in different engine sizes; you only need to crosscheck your most comfortable size with your requirements on a size chart to determine the best fit for you and your kids.

All in all, ensure that you remind your children to put on quality safety gear when riding their motorcycles.

If you look at a size chart, you’ll quickly understand and identify the most recommended model for you because the list comprises all sanctioned dirt bike heights and their respective engine sizes.

Dirt bike height charts vs. dirt bike size charts

The designers of dirt bike height charts often encounter numerous challenges when matching seat elevations with different kids’ heights because children differ in body types, lengths, and sizes.

A kid with longer legs can comfortably ride a dirt bike with a taller seat, while those with shorter limbs cannot. Making a comprehensive size chart to accommodate all children’s heights takes a lot of time and effort.

However, some designers created detailed charts that indicate the different dirt bike sizes corresponding with the right children’s heights.

The charts do away with the common confusion that creates a problem for customers as they choose the perfect bike sizes for their children and themselves.

Dirt bike charts will help you significantly when choosing the right bike sizes for you or your family because you’ll know what to look for or avoid.

The tables also give you exact height specifications and the right dirt bike for the owner regardless of their age. Incorporating a size chart in your hunt for the perfect motorbike can significantly affect your choice by offering you better insight.

It would help if you chose a 50cc dirt bike for a child aged three to 8 years. Eight to ten-year-olds should use 110cc bikes, and 10 to 12-year-olds should ride 110cc to 125 cc dirt bikes.

5”2” to 5”10” riders should pick between 125cc to 250cc bikes, while 6-foot tall motorcyclists need to pick 450cc models.

You can estimate the rider’s approximate height or age and compare it to the corresponding dirt bike size to know precisely the right design for you. When choosing dirt bikes for kids, use the same assessment criterion as well.

Riders should study height and size charts and use them as reference points when selecting motorbikes. Each category of riders will find the recommended engine size, as indicated in cubic centimeters.

When choosing the right dirt bike size, you should look at two critical factors: the location of a seat on a dirt bike in connection to the rider’s height and comfort.

High seats often make it too uncomfortable for younger or shorter kids because they can hardly gain better control of the handlebars due to their arms’ short height.

How to find the right dirt bike size for your kid

When rummaging through warehouses in search of the right bike for your children, please tag them along so that they can try out different bikes.

Dealers allow children to sit and test their rides to see if they suit their needs. However, parents can also customize taller or shorter bike seats to fit their children’s riding and comfort needs.

Why do we recommend that kids physically try out different dirt bikes before making the right pick? Children often express their honest feedbacks about new experiences, unlike adults who can sometimes hardly express their honest encounters.

Taking your children out with you on the search for the appropriate dirt bike guarantees the right selection. After getting the riding or comfort experience from your child, you can subsequently refer to the size chart to determine the perfect model for your kid.

Dirt bike riding gets fun when you use the right design, so make sure you pick the right size for either you or your loved ones.

Basic interpretation of a dirt bike size chart

Primarily, a size chart will outline for you the critical factors you ought to consider when choosing your motorcycle.

Understanding the factors and keeping them in mind during acquisition will guarantee easy selection and keep you from making poor decisions in your investments. Motorbikes don’t come cheap, so buying the right one will save you from flushing your pennies down the drain.

Consider these factors when researching and purchasing motorbikes for you or your kin:


Before considering their height or ages, consider first your children’s safety and the right ways of keeping you and your kids safe during riding. Children start learning how to ride bikes at tender ages – they lack experience and a keen eye to watch out for obstacles on the road.

You should provide your children with safety lessons and gear to protect them from frequent falls and crashes because they could easily get into accidents, even with the best dirt bikes.

We recommend parents only to allow their kids to ride unsupervised once they know for sure that nothing can get between their safe riding and the thrilling adventure of motorcycling.

Youth and adult riders should also adhere to safety recommendations, even though we emphasize more when it comes to children. For example, a five-year-old won’t comprehend the risk of riding unsupervised or without safety gear.

As a parent, you owe children duty and responsibility to keep them safe and ensure they don’t get injured while riding by setting up all the necessary measures that warrant their protection.

Some experts even advise parents not to purchase bikes for their children aged under three years. Children aged three years and above can thus ride bikes but only under strict supervision for younger children.

You can start training your ten-year-old kids to ride dirt bikes by getting them the 50 or 110cc bikes. Small engine designs will offer safety while giving your children a glimpse of what it would feel like to ride a real and powerful dirt bike.

If you don’t know the proper safety guidelines to follow when instructing your children on their riding, make sure you get a copy of the beginner bike guideline.

You can also refer to dirt bike size charts because they provide accurate and detailed information on all riders’ safety requirements.

Parents can get more powerful bikes for children aged eleven years old and above because their experience level allows them to control more dynamic engines than their ten-year-old counterparts.

Also, don’t forget to use the dirt bike size chart when acquiring different children’s bikes because choosing the wrong design could cause you or your child harm.


Choose the right bike by comparing the rider’s height to the bike’s tallness. Considering the bike and rider’s height guarantees comfort and makes the riding experience more fun and adventurous.

Your children will appreciate it if you considered height when purchasing their dirt bikes. The right bike height should match your child’s body length and height because of their differing and small sizes.

Don’t rely on guesswork if you want to avoid returning after every couple of hours to try out a different dirt bike for your kid. Instead, visit the bike warehouse with your child and allow them to mount different bikes and determine their most perfect rides.

Don’t purchase an extremely low or high bike in comparison to your kid’s approximate height. If they sit on the bikes themselves, you’ll see the bikes that suit their heights.

Many beginners make the mistake of purchasing short bikes for their children. Don’t fall into the category of unknowing buyers. Parents most likely assume that shorter designs make comfortable rides for their children.

A shorter bike won’t guarantee the safety of your child. Aside from causing common muscle complications, the models can cause severe injury to the child.

A dirt bike height chart will make your purchasing more manageable because it indicates the right information about children’s heights and their recommended bike heights.

Besides, you can consult a size chart or size calculator to get the best estimation of motorcyclists’ heights in connection to their bike sizes.


Rugged terrains make it critical for riders to consider comfort in their bikes. An uncomfortable ride will make traversing rocky terrain harder and tiring. Make sure you pick a dirt bike that guarantees comfort throughout the riding experience.

Some bikes come with excellent functionality, performance, and durability but lack specifications for comfort.

When purchasing a dirt bike, please ensure that it comes with relaxation features such as thickly-padded shock absorbers that can disseminate impact and keep your ride comfortable.

The seats should contain thick foam linings that won’t bulge or cause you any discomfort when riding on any terrain. Before purchasing the dirt bike, try out the impact absorbers to ensure they work correctly and withstand potholes, different grounds, rough paths, and bumps.

It would be best if you considered finding more comfortable alternatives for children because, unlike grownups, kids lack the strength to withstand frequent impacts and thus need bikes that warrant them topmost comfort at all times.

Children can gain better confidence and experience as future riders if they trust that their bikes will give them assured and prolonged comfort.

A size chart lists the nature and size of dirt bike seats and provides enough information to help you choose the most comfortable rides for your kids and yourself.

Adjusting the height of a dirt bike

Some riders hardly know how to regulate their dirt bike heights. You might purchase a dirt bike that seems taller but return it to the manufacturer only to learn that you can adjust its height.

Height adjustability can provide the right comfort needed when riding. Riders can either raise or lower their motorcycle heights without any difficulties.

  • Lowering dirt bike heights

You can lower dirt bike heights by adjusting seat heights. A motorcyclist can reduce the seat height by chopping off some of the foam. Slicing a small quantity won’t affect your comfort but will regulate the bike height and suit some of your riding needs.

Besides chopping foam, you can replace the original one with softer modified foam to guarantee better comfort. If the dirt bike seat contains thicker and heavier foam, riders can drill holes into the seats to create a sinking sensation every time someone sits on the bike.

Lastly, riders can regulate the slump on the bike’s lower moratorium. The slump allows riders to make suitable adjustments depending on their needs and preferences.

  • Raising dirt bike heights

You can add a hard or thick foam on your seat to raise its height and suit your demands. Rigid foams can add up to two extra inches on top of the existing height.

When adding foam to your bike seat, make sure you carry out the process correctly and that the attained height suits you perfectly.

Slump settings on rear suspensions work best in increasing dirt bike heights. Despite its effectiveness, slump adjusting can cause slight adjustments on your steering.

After replacing foam seats with taller ones, look for taller handlebars that will make slight alterations to your bike and improve overall steering and comfort.


A dirt bike size chart will help you choose the right bike for you or your kids by indicating all the seat heights and engine sizes corresponding to different riders’ heights and needs.

When picking children’s motorcycles, you should consider their comfort, heights, safety, ages, and experience. A 5-year-old cannot ride the same bike as an eleven-year-old. Besides, older children can ride more powerful bikes with 50 to 110 cc engines, while their younger siblings cannot.

Remember to test different dirt bikes in the market by mounting them to feel comfort levels offered by bike seats. When purchasing kids’ bikes, take them along and allow them to try out various bikes before picking the right ones.

After getting their feedback, reference your children’s heights with the right dirt bike sizes before approving their motorcycle choices.

Aside from choosing the best bike, make sure you adhere to safety recommendations by putting on the right equipment when riding.

You should primarily ensure that your children understand the importance of safety gear, keep them geared up during all rides, and monitor them when riding. Also, don’t purchase bikes for young children below three years.

All in all, ensure that your bike choice suits your riding needs and gives you comfort when riding, especially on rugged grounds.

Riders should stay up to date with dirt bike types and occasionally review the size and height charts for professional recommendations on the best bikes to acquire.
