How Fast Does A 250cc Dirt Bike Go?


The speed of a dirt bike depends on its brand and engine quality. Although after tests on different bikes, it is found that a 250cc dirt bike’s speed lies between 70-85 mph, still many of motorcycle’s range 50-60 mph. For some special circumstances, these bikes can’t go up to 100 mph. Even there are few techniques to enhance its range from 50 to 80 mph. 

This is frequently asked question and asked by most of the dirt bike riders.

If you want to do a adventurous riding in a hilly area, you must go for lightweight and low cc motorcycles. And you need to know what are the factors responsible for the speed of any bike. 

What is a 250cc Dirt Bike?

Actually these low cc dirt bikes are recommended to the mediator riders who have experience of two to three months of riding.

It is never recommended for beginners, as these bikes can go so fast that it’s not good for the freshers.

Higher speeds can be dangerous for them, so learning a new skill of riding goes for a 125cc dirt bike. Also, you need more effort to control this bike, adults love such featured motorcycles. 

Factors on which dirt bike’s speed depends:-

Behind every performance, a list is there, it can be a list of hard work or techniques or reasons. Here, you will see the list of elements responsible for the bike’s speed. 

Brand of dirt bike: When you bought your dirt bike, you noticed a variety of bikes were available there. What you want will depend on how you plan to get the goal. Similarly, to get the highest speed for a 250cc dirt bike, keep your eyes open to see which one is fulfilling your desires. It’s not like that the branded one will always be best for speed purposes, there are plenty of options made for a faster 250cc dirt bike. 

Weight of seat: You should know your bike’s weight matters for its speed. You can make it lighter by changing the seat and its cover. A bike is an assembly machine of different parts, lighter parts means all over will decrease automatically. 

Weight of tires: It also affects the speed of the bike, but don’t invest in the cheaper one that’s so light. Yeah, replace the heavy tires with the lighter tires, but make sure they can run longer without putting your life at risk. 

Gearing system: Gearing is also an option that can enhance the speed of your bike, it affects the acceleration or top speed of your dirt bike. You can’t hit the maximum gear, do it part wise to achieve the required speed. If you don’t have knowledge about the gearing ratio, take help from others who have more experience than you. It is calculated how many teeth are in your rear sprockets and front sprockets, having a perfect ratio will maximize the grip by moving the tire rotation. 

Front and rear sprockets: A faster speed needs larger sprockets at the front and small sprockets at the rear. You follow this step if riding in a sandy or desert area, the following process will maintain higher speed. 

Whereas riding on a track or in a mountain area, switch the sprockets, the larger one with the smaller one and vice versa. These two procedures preserve the gearing ratio. 

Light exhaust system: An exhaust system contains some kind of metal to cover it for any damages. Usually, in the market, the exhaust system is covered with steel or aluminium metal that are heavier. You need to dig deeper for a titanium exhaust system which is too light and also stronger than the previous two metals. 

Rider’s experience: You may have the most expensive and branded dirt bike, but there is no meaning to buy such motorcycles if you don’t know how to ride it. You will never experience its highest speed until you know how to manage bike riding perfectly. Don’t take my words as someone who doesn’t know how to ride, it’s so easy. Let me clear you, riding a bike doesn’t mean to start a bike and balance it on the road. 

Until you know how and where you need brakes, shift, move with the speed without hesitation and how to lean yourself at turning. So, if you want to have fun riding in the mountains at the fastest speed, let’s gain more experience.  

Rider’s weight: Your single decision can affect your whole life, keep your weight balanced. You have a good racing dirt bike, the best experience to ride a bike and also techniques to make your 250cc motorcycle faster. But, what if you are a heavyweight, this will put you down. More weight means a lower speed of the bike. 

Motocross track: There are different types of tracks, mountain areas or artificial tracks. Also, what kind of dirt is used on such motocross affects the speed of a 250cc dirt bike. Obstacles are also there that resist the maximum speed of a dirt bike. While choosing or constructing a motocross track, must be aware of what is suitable for your motorcycle? 

A clay-based track is always great to enjoy riding. It does not produce potholes easily even in heavy rains, it can be seen after a long time. 

Many of the tracks were constructed with challenging obstacles or jumps, these should be longer so that no rider will fall. 

And the most important aspect of these tracks is their underground system. If there were drainage, this must be covered appropriately.

Clay can easily soaked down into the drainage when it rains and can create flooding in your track. These all four: track design, dirt, obstacles and drainage system subvene motion. 

2 Stroke Or 4-Stroke 250cc Dirt Bike?

Which one is best between a 2 stroke and 4 stroke dirt bike? Let me tell you these two are different in many cases, such as top speed, acceleration limit and other varieties too. 

Two-stroke engines are more comfortable as compared to the four-stroke engines.

You need less force to start these kinds of engines, only two pistons are required instead of four. The two-stroke starts its engine with a force to push down the air-fuel mixture until it reaches the exhaust.

And while it’s going down, extract the previous air-fuel mixture from the crankshaft and while coming upward, an exposed transfer port allows fresh mixture to be into the cylinder.

At the same time, the crankshaft starts moving and pushes back the piston upward. 

Piston blocks the exhaust and intake until the air-fuel mixture compresses. A 2 stroke engine takes less time to start but every time you use a piston to start the dirt bike, during the process it releases a few amounts of fuel.

Although a 2 stroke engine dirt bike needs more maintenance at a low cost as its parts are cheaper. It’s lightweight and faster as compared to the others and more torque at higher RPM. 

While we talk about a 4 stroke engine, it needs four-piston movements to complete an engine cycle: Intake, compress, power and exhaust. Four-stroke bikes are good for the beginners, it fires twice that delivers sufficient power.

A 4 stroke engine bike needs less maintenance as it works frequently well. These kinds of bikes are heavier and require more time for cleaning.

Also, you can’t go for a faster ride on hilly areas due to its heavyweight.   

All I want to say is, two strokes gives you a higher speed than four strokes. So, it’s one of the factors that affect how fast a dirt bike can go. 

How can you increase the speed of 250cc dirt bikes?

There are several techniques with which you can enhance your bike’s speed. I’m mentioning those modifications that can help your 250cc dirt bike to get the highest speed. 

  1. Replace the rear sprocket this will restrict the rear tyre to be failed soon. 
  2. Make your dirt bike lighter than its original weight. Once you do it, the bike will automatically pick up the highest speed. 
  3. Always use a good quality fuel better to have a premium one, you will notice a slow speed bike will improve with these little changes. 
  4. Change the stock air filter with a branded and better working set. 
  5. If running on older tyres, replace it quickly. A new set will enhance the speed of the bike. 

May these hacks sound not much interesting, but don’t conclude before seeing the improved result. 

Note:- If this is your first time riding a dirt bike, a 250cc motorcycle is a good option and also good for seasoned riders. For those who love to ride on highways, we recommend you buy a bike with more power. It’s good for anywhere, but to enjoy your ride at the highest speed, then move to the next level of power. 

Conclusion

Riding a motorcycle is fun and when you ride it at maximum speed that’s another level of enjoyment.
