Riding dirt bikes is a fun hobby that you can engage in with friends, family or alone. As you tear up the trails while exploring new places and immersing yourself in this new hobby, you will realize how therapeutic it is to ride a dirt bike.

However, before riding your 250cc dirt bike on mountain terrains and motocross track, remember you will require a bit of practice to reduce the chances of getting yourself into an accident.

If you are a pro at dirt bike riding and you want to experience real power while riding, then get a 250cc dirt bike. 250cc dirt bike delivers powerful acceleration with high performance.

Depending on the type of engine, a 250cc dirt bike comes at a maximum speed of between 55 to 70 mph (90-113 km/h).

Factors that Affect Dirt Bike Speed

Many factors affect the speed of a dirt bike, and we are going to look into those factors and how you can increase your dirt bike’s speed.

Dirt Bike Brand, Weight and Tires

There are different types of 250cc dirt bikes available in the market. Each of these types has their own alterations and specifications that make them unique. The brand of your bike will determine how fast your 250cc dirt bike will go.

For instance, an Apollo 250cc dirt bike has been designed for a maximum speed of 60 mph, while a Roketa 250cc dirt bike goes for a maximum speed of 55 to 60 mph.

To improve the speed of your dirt bike, there are a few alterations you can perform on your 250cc dirt bike. However, remember not to tamper with the original structure of the bike, which can affect your bike’s stability. Some of these alterations include;

Weight of the Tires

The weight of your bike’s tyres will affect the speed of your bike. Lighter tires result in faster speed compared to heavier tyres.

You can change your tyres weight by not adding tire slime or mousse to the tyres. However, remember this comes with increased risk, but so does riding a bike.

Weight of the Seat

Cutting down the general weight of your dirt bike is a sure way of increasing its speed. While the seat you bought your bike with is okay, you can opt for a lighter seat and seat cover.

This will not only help to increase your bike’s speed, but you could also get a more customized and comfortable speed.

Exhaust system

Other alterations you can perform on your bike to make it lighter include changing your exhaust system from aluminum or steel into a titanium system exhaust.

Titanium is lighter compared to aluminum and steel, but be ready to dig deeper into your pocket.

Rider Experience and Skill

You may have the best, most recent or expensive dirt bike, but if you do not know how to ride it, then you will not experience the fullest potential of the bike. Riding a dirt bike does not only entail knowing how to balance the bike and general knowledge starting it.

However, skill and experience is what you gather over many days of practicing how to ride your dirt bike. Constant will help you to shift, brake, lean in turns, and move with your bike at a good speed in a matter of nature and reaction and not an action that requires you to sweat as you try to make decisions.

So if you want to be the fastest on the mountains trails, then invest more hours in gathering more experience and skill.

Rider Weight

Cutting down the weight of your dirt bike will improve its speed. However, as sad it is, your weight as the rider will also have an impact on the speed at which you can ride your 250cc dirt bike.

Even with great experience and technique, while racing on a dirt bike track or a trail, your weight will affect your final position, winner, first runners up, second runners up or no placing at all.

Motocross Track Layout

There are different types of tracks, each with its own type of dirt, which determines greatly how the race turns out. Obstacles put up for each motocross track will determine how fast you are going to ride your dirt bike.

Whether it is a natural track on the mountains or an artificially constructed track on a field or on your backyard, the speed will vary with how smooth and the type of dirt on the ground. While constructing a motocross track for your dirt bike riding experience, remember:


Clay is the best-based dirt for building your motocross track layout. The clay-based track will not need much maintenance because it does not develop potholes easily.

Whether you are building on a flat field or depending on natural contours, you will definitely have to bring in some dirt.

Jumps and Obstacles

Jumps and whoops make a motocross track layout interesting and more challenging. You can use logs to fill in the jump rather than using dirt.

Make the jumps long and wide so that they do not throw off the riders around.

Access and Parking

If you intend to open up your motocross to the public for racing, then consider having access and parking space before you fill out the entire area with the track itself.

The parking space should be preferably on flat land. Additionally, this space can also be used as access for machinery such as bulldozers and excavators that you will be using to construct the track.


A good motocross track should be designed with proper drainage. Clay can get compacted easily when it rains, hence soak little water. Therefore, a little downpour can cause flooding in your track with poor drainage system.

2 Stroke vs 4 Stroke Dirt Bikes – Which is Faster?

2 stroke dirt bikes have an engine that has two main functions, compression and combustion. 2 stroke dirt bikes are lighter and cheaper compared to 4 stroke bikes.

4 strokes on the other hand have engines that have four main functions, combustion, exhaust, intake and compression.

There is no comparison between the two in terms of functionality. Each has an advantage over the other.

Riders are looking for high performance engines that will allow them to ride the bike faster without any hustles. The question of which is faster or better between the two lies on the rider, their preferences and skill.

Wrapping Up

Dirt bike riding is a fun activity. Most riders will tell you the faster the better. If you would like to move at a good speed while keeping safe, then get yourself a 250cc dirt bike.

However, remember, the speed at which you move will greatly depend on a number of factors, including the rider’s experience and skill.
