How Fast Does a 250cc Dirt Bike Go

Updated on August 18, 2022

A 250cc dirt bike can go 55 to 80 mph or around 90 to 113 km/h, although it depends on the gear. 250cc bikes can accomplish above 80mph of speed, but they can’t get past 100mph under usual circumstances due to their limit established for street riders. So, you’ll normally find these dirt bikes limited to roughly 80 mph.

If you’re thinking about making the switch to a four-stroke motorcycle, you might be curious in the top speed of this model. It all depends on the model, as well as other variables.

Suzuki’s RM-Z250 4-stroke dirt bike, for example, can reach a top speed of 85 mph. Power, speed, and manoeuvrability are the primary goals of this bike’s design. These, of course, have reasons, including changes to the bike’s engine.

As a newbie, you can expect to put out up to 249 cubic inches of displacement from the four-stroke engine. With the five-speed transmission, this will undoubtedly increase the speed to around 85 mph.

Factors that Affect Dirt Bike Speed

Increasing the speed of your dirt bike can be accomplished through a variety of methods, all of which we’ll examine in this article.

Dirt Bike Brand, Weight and Tires

In the market, there are a variety of 250cc dirt bikes to choose from. Each of these varieties has its own distinct modifications and characteristics. The top speed of your 250cc dirt bike will be determined by the brand of your bike.

An Apollo 250cc dirt bike, for example, has been engineered for top speeds of 60 miles per hour, while the Roketa 250cc dirt bike is capable of speeds between 55 and 60 miles per hour.

You may make a few modifications to your 250cc dirt bike to boost its speed. Even if you have a lot of money, don’t mess with with the bike’s original structure. As a result, some of these changes include:

Weight of the Tires

When it comes to your bike’s top speed, your tyre weight is a major factor. With lighter tyres, you’ll go faster than you would with heavier ones.

It is possible to alter the weight of your tyres by removing tyre slime or mousse from the tyres. The increased danger, though, is the same as riding a bike.

Weight of the Seat

Increasing your dirt bike’s top speed is as simple as reducing the bike’s overall weight. Seat covers and lighter seats are options if you don’t mind replacing the one that came with your bike.

Speeding up your bike is only one benefit of using this method, but you may also be able to reach a more personalised and comfortable speed.

Exhaust system

Other modifications you can make to your bike to make it lighter include replacing your aluminium or steel exhaust system with a titanium exhaust system.

Compared to aluminium and steel, titanium is more affordable, but you’ll have to spend more money to get it.

Rider Experience and Skill

Even if you have the most up-to-date or costly dirt bike on the market, if you don’t know how to ride it, you won’t get the most out of it. It’s not enough to know how to balance a dirt bike or how to get it started.

When it comes to learning how to ride a dirt bike, though, practise is the key. With Constant, it will be easier for you to shift and stop your bike as well as lean into corners and go with your bike at a good speed without having to worry over making judgments.

Spend more time honing your skills and gaining experience to be the fastest on mountain tracks.

Rider Weight

Your dirt bike’s speed will increase if you reduce its weight. However, your weight as a rider will have an impact on the pace at which you may ride your 250cc dirt bike.

Even if you have a lot of expertise and a lot of technique, your weight will have an impact on your final place in a dirt bike race, whether you finish first, second, or last.

Motocross track layout

Depending on the type of dirt on the track, the outcome of the race can vary dramatically. Each motocross track’s obstacles will dictate how fast you can ride your dirt bike.
Depending on how smooth and what kind of soil is on the ground, the speed will vary whether it is a natural track in the mountains or an artificial track in a field or your backyard. If you’re going to build a motocross circuit for your riding pleasure, keep these things in mind:


Your motocross course should be laid out on clay dirt. As a result, the clay-based track will require little to no maintenance.

Dirt will have to be brought in regardless of whether you are building on a flat field or relying on the natural contours.

Jumps and Obstacles

A motocross track’s layout is made more fascinating and difficult by the inclusion of jumps and whoops. If you don’t want to use dirt, you can fill in the leap with wood logs.

In order to keep the riders from being thrown around, make the jumps as long and wide as possible.

Access and Parking

Prior to constructing the motocross circuit, evaluate whether or not you will be able to accommodate spectators or visitors.

Ideally, the parking area should be situated on a level surface.. As a bonus, you can use this area to access bulldozers and excavators that you’ll need to build the track.


Designing a motocross course with correct drainage is an important part of making a great one. When it rains, clay can easily get compacted, so it only soaks up a small amount of water. The insufficient drainage system in your track means that even a light rain can create floods.


Is a 250cc dirt bike fast?

Is a 250cc dirt bike too big?

Is 250cc good for a dirt bike?

Yes. Inexperienced riders or those who prefer a decent mix between power and manoeuvrability might consider a 250cc engine.

When selecting a convertible motorbike, engine size is an important issue. The amount of air the engine can take in determines the size of the engine, which in turn indicates how much power it will create.

Is a 250cc dirt bike good for beginners?

Yes. A 250cc dirt bike is a fantastic choice for novice riders who are looking for a low-maintenance and easy-to-ride machine. To get the most out of the experience, a 125cc motorcycle may be the best option.

Final Thoughts

Consider the variables listed above while shopping for a new dirt bike. The thrill of a dirt bike ride comes at the cost of a little extra time and caution. Spend your money on something you know nothing about before you end up with a clunker that can’t keep up with your demands.
