Ultimate Dirt Bike Size Chart and Seat Height Guide

The dirt bike seat height and other dimensions of the bike are important selection criteria for many riders looking to buy a dirt bike. The height and weight of the rider may also set additional requirements for the dirt bike size.

Riders should also focus on few other things, such as the riding style and rider experience, when choosing the perfect first dirt bike—or the next one or whichever the number of your bike is.

This in-depth dirt bike size chart and selection guide will help you to find the correct dirt bike size based on the type of dirt bike riding you are planning to do and based on your experience and skill level. We will also explain how to tune the selected dirt bike to your height and weight and, if necessary, how to lower the seat height to your liking.

What Dirt Bike Size Is a Good Fit for You?

You may be asking yourself: what size of dirt bike do I need? Well the answer is actually quite simple and these dirt bike size charts will help you find the ideal fit.

Let’s start by going through few important selection criteria for your dirt bike and how the dirt bike seat height can help you find the ideal dirt bike for your height.

In addition to the dirt bike size, dirt bike dimensions, and the seat height, you should select the dirt bike from the correct type of off-road motorcycles that fits your riding style and skill level.

If you are planning to do enduro, single track, or trail riding, choose a dirt bike from the cross country or trail lineup. If you ride motocross, stick with dirt bikes designed for track or motocross.

Different manufacturers use different terminology and model names and sometimes it’s difficult to know exactly which dirt bike model or dirt bike category is the best for you. For this reason, we gathered the most common dirt bikes into dirt bike size charts based on the riding style and skill levels.

Additionally, think about the overall weight of the dirt bike. Many beginner riders struggle the most with the weight of the dirt bike at the beginning. Among other things, you need to be able to load your dirt bike into a truck or a trailer and unload after a long day at the trails.

Dirt Bike Size Charts

Below, you will find generic dirt bike size recommendations based on your height, matching skill levels, and riding styles.

1. Beginner Dirt Bike Sizes for Trail Riding

Beginner riders looking to buy their first trail riding dirt bike should stick with cross country models.

Additionally, when selecting the correct model, do not let the engine size scare you or drive the decision process too much. Typically, these beginner models are tuned in such a way that they are more forgiving and mellow, which helps with getting started and learning the basic techniques. The available low-end torque is more important than the engine size in CC (or cubic centimeters).

A great example is Beta XTRAINER. While it has a 300cc two-stroke engine, the engine is tuned to a very mellow and tame power delivery curve. It makes it hard to stall as well as very easy to control and learn the proper clutch operation. It also has a lowered dirt bike seat height and a lighter overall weight compared to other full-size Beta models.

Engine Size as Selection Criteria

Another misconception is that small engine dirt bikes make great beginner dirt bikes. This is not necessarily true.

For example, if you have ever tested the Yamaha YZ125X or KTM 150 XC-W models, you know what we mean. They both are very-difficult-to-learn beginner dirt bikes for few reasons. First of all, the YZ 125 dirt bike seat height is 38.6″ or 98cm. KTM 150 XC-W has a seat height of 37.8″ or 96cm. In short, these are tall dirt bikes.

Secondly, think about the clutch and the low-end torque. Small engines, such as those in the above-mentioned dirt bikes, do not have a lot of low-end torque available. This means that learning how to operate the clutch is more difficult than let’s say with the Beta Xtrainer. Basically, this means that in order not to stall the dirt bike, you need to use more gas to rev the engine much more and this can be dangerous and difficult when learning the basic skills.

Next, let’s take a look at our recommended dirt bike height chart for beginner trail riders.

2. Beginner Dirt Bike Sizes for Motocross

Motocross dirt bikes are commonly four-strokes and have larger rear wheel sizes. This also affects the overall dirt bike height.

Full-size cross country or trail bikes have 18″ rear wheels, whereas full-size motocross models use a 19″ rear wheel size. Furthermore, they also sit slightly higher in seat height due to a longer suspension travel for bigger jumps and deeper sand.

Modifying the Dirt Bike Size or Seat Height To Fit You

The correct dirt bike ride height is one of the most important factors when it comes to dirt bike ergonomics. You want to feel comfortable on your dirt bike and a stable footing might just give you that little extra confidence with learning new techniques—especially when you are a beginner rider.

If you don’t yet have a dirt bike, you should start by choosing the right dirt bike for your height. That’s probably the easiest way to get the dirt bike ride height spot on. So, hop on as many dirt bikes as you can and see how they feel like.

Keep in mind that dirt bikes by design try to maximize the clearance and therefore sit much higher than street bikes or most adventure bikes. And there is a solid reason for this: they are made for off-road riding and for more challenging terrain.

A rule of thumb for beginners; the ball of your foot should touch the ground at least on one side.

We are both 5′ 8″ and in our opinion, this is the minimum height for most full-size dirt bikes, such as KTM, Husqvarna, Beta, GasGas, Yamaha, and similar brands.

However, don’t worry if you are shorter than that and cannot find a dirt bike that fits you—there are few ways to quickly lower the dirt bike ride height. We will tell you all about them shortly!

Finding the Correct Dirt Bike Seat Height

Sit centered on your dirt bike with your body in a neutral position and your arms slightly bent.

In this position, when the dirt bike is standing straight, are you able to touch the ground at least with the ball of your foot on one side? If yes, you’re good. You don’t need to reach the ground with both of your feet or with the heel.

If you cannot reach the ground with the ball of your foot on one side, consider lowering your dirt bike seat height by modifying the suspension or modifying your seat.

Adjusting the Dirt Bike Seat Height

If you already have a dirt bike but it feels too tall for you, there’s no need to call it quits. Instead, let’s focus on making it fit you better.

If you are shorter than 5′ 8″ or you feel like getting a stable footing would make it easier to learn beginner techniques, you should look into lowering kits. However, there are few things you can do before that to affect the ride height and overall dirt bike size.

Setting the Dirt Bike Sag and Tuning the Suspension Is Important

Firstly, you should set your dirt bike sag and tune the suspension properly. You should do this even if you don’t need to adjust the ride height. The sag affects how the dirt bike performs and reacts to different riding conditions and it is an easy way to ensure your dirt bike is performing well.

Setting the sag will affect the active ride height. So, you should set the sag correctly before deciding to further lower the bike. Make sure to check out our detailed guide on how to set dirt bike sag.

Secondly, take a look at your seat. Setting the dirt bike seat height is an affordable and simple solution to fine-tune your ride height as well as the overall ergonomics of your dirt bike.

Shaving the dirt bike seat is probably the easiest way to make a dirt bike 1 to 3 inches lower. You can also change the seat to a completely different one.

There are seats that lower the ride height up to one inch. However, these seats can be a bit harder because they typically contain less cushion material in order to achieve a lower profile. They may become uncomfortable in some riding styles but are a great option for adjusting the ride height instead of lowering the dirt bike.

Read our tips for choosing the perfect dirt bike seat to further tune the overall seat height.

Okay, so these tricks weren’t enough for you? Then, let’s take a closer look at the lowering kits.

Can you lower a dirt bike is a question we hear often. The simple answer is yes. You can do that yourself with aftermarket parts that fit inside the front fork legs and rear shock or ask the shop to lower it for you before buying the dirt bike. You can also look for used dirt bikes that are already lowered.

One of the most efficient ways to lower the dirt bike ride height is to install a lowering kit.

Lowering the seat height of a dirt bike with a lowering kit is an easy and efficient way to lower the overall dirt bike ride height. It can drop the ride height and dirt bike size even up to few inches. However, lowering kits can be a bit pricey so that’s why we recommend trying out the other tricks first.

Here are few example lowering solutions that we can recommend especially for beginner riders:

These lowering kit doesn’t require changing springs, which makes it an affordable option. You can find similar options for other models by searching “lowering kit” on your favorite parts sites. Note that when lowering the seat height of a dirt bike, the rear shock will need to be lowered at the same time to keep the dirt bike balanced and riding well.

Raising the Ride Height for Taller Riders

What about if you’re a taller rider and your dirt bike size feels too small for you? Again, no need to worry. There are some easy tricks to raise the dirt bike ride height as well!

Firstly, you can get a taller seat. Assuming you have set the sag correctly, the seat height is one of the ways to make the dirt bike more comfortable for your height. Reaching the ground is not an issue for taller riders, but the seat height might need adjusting for some riders.

Secondly, you can get handlebars that have a taller profile. Furthermore, you can modify the handlebar setup in different ways. Handlebars themselves come in various sweep and height dimensions and it can help many taller riders with a longer hand reach. Another thing is to adjust the handlebar position in the triple tree. There are commonly four settings in the triple tree to move the bars more forward. You can also add taller handlebar risers on the triple trees to lift the bars to your liking.

Thirdly, you can change the shock pre-load. Some forks come with a spring preload adjustment and adjusting it to your weight class will ensure the front end will be on the correct active ride height.

Fourthly, you can adjust the fork height in the triple tree clamps. This is more of a fine-tuning method. Just don’t forget that the height affects the riding characteristics of the dirt bike. Make sure that you keep the active ride height level with the rear so that the dirt bike is balanced.

Dirt bike size chart for the model year 2023: off road dirt bikes for enduro, motocross, cross country, and trail riding

Common FAQs Answered about Dirt Bike Sizes

What size dirt bike do I need?

In addition to the dirt bike size, engine cc, dirt bike dimensions, and the seat height, you should select the dirt bike from the correct category that fits your riding style and skill level.
If you are planning to do enduro, single track, or trail riding, choose a dirt bike from the cross country lineup. If you ride motocross, stick with dirt bikes designed for track or motocross. Next, choose the seat height and engine size based on your height, weight and skill level.

Is a 125cc dirt bike too small for adults?

No. The riding style, rider level, track / trail type defines the ideal dirt bike engine size for you. Many advanced adult riders enjoy 125cc dirt bikes and outperform bigger dirt bike riders in any trail.

How tall do you need to be for a 125cc dirt bike?

You can find 125cc dirt bike models for most rider heights. Tall, full size dirt bikes, such as the popular Yamaha YZ125X, have relatively high seat height of 38.2″ (970mm), making it ideal for riders 5′ 8″ or so. But you can easily find lower seat height dirt bikes and even lower them. Take a look at this post for more available options for your height.

Is a 125cc dirt bike good for beginners?

Yes. When choosing the correct dirt bike model, the 125cc dirt bikes make great beginner dirt bikes. They are light, easy to master and relatively affordable. However, choosing the 4 stroke model for beginners can help learn clutch and basic operation easier as it has more stall proof low end torque.

Are there any adjustments or modifications I can make to a dirt bike to accommodate my size better?

Yes, you can lower the dirt bike suspension or raise the handlebars and adjust to seat height to mention a few. Read more in this post to learn how to find the fit and how to adjust and tune your current dirt bike to fit your height.

Conclusions

Finding the best dirt bike size on the correct dirt bike category is important when choosing a new dirt bike.

When testing different dirt bikes for size, you should be able to touch the ground with the ball of your foot on one side when you are sitting on the dirt bike. Do not lower you bike too much just so that you can reach the ground better. Sure, it is important to be able to touch the ground but a ground clearance is even more important when it comes to trail riding, enduro, and motocross.

And if your current dirt bike feels too tall or small for you, there are luckily few ways to adjust the dirt bike ride height. Just make your dirt bike fit for you and hit the trails or tracks!
