After riding a 125cc dirt bike, you must be thinking it’s time to upgrade now. You are planning to get a 250cc dirt bike, but you first had to research its speed.
How fast do 250cc dirt bikes go?
Do they provide perfect riding conditions? By perfect riding conditions, we mean smooth tracks and good weather.
However, it’s worth mentioning that factors like engine size, bike weight, rider’s weight, and rider’s experience influence the dirt bike’s top speed just as much as the riding conditions.
So, we are going to take a look at how those factors affect the dirt bike’s maximum speed. But before that, let’s first compare a 250cc 2-strike with a 4-stroke.
- Stroke vs. 4-Stroke
2-stroke engines have two main functions - compression and combustion. They are less complicated and complete their cycles in only two motions. They are also pretty lightweight which makes them faster.
4-stroke engines, in contrast, have four functions - intake, compression, combustion, and exhaust. They are heavier than 2-stroke options. These bikes are easier to maintain and less noisy.
Taking to speed, a 250cc two-stroke dirt bike can hit 70-85mph under favorable conditions. And on the other hand, a 4-stroke has a top speed of about 70-80mph.
However, it’s not just the speed, you also have to consider the following:
- Dirt bike size
- Tires quality
- Suspension types
- Engine size and strength
- Rider’s experience level
Factors that Affect the Top Speed of a 250cc Dirt Bike
Bike’s Weight: A lightweight dirt bike will be easy to ride and can go faster. Thus, consider the bike’s overall weight when picking up your next 250cc dirt racing engine.
Engine Size: As far as the engine size is concerned, a two-stroke is generally faster for being lighter.
Dirt Bike Brand: Different dirt bike brands have different top speeds. So, choose the one with 2-stroke or 4-stroke as per your requirement and suitability.
Rider’s Experience: Of course, an experienced biker rides faster than a newbie. The more experienced you are, the better you can balance and maneuver the bike.
Tire’s Weight: Lighter tires go at a much faster pace than heavier ones. So, if the tires of your 250cc dirt bike are heavier, replace them with lighter ones to improve your overall speed.
Exhaust System: The material type of your exhaust system greatly influences the bike’s overall speed. For example, replacing a steel exhaust system with an aluminum one can improve the speed.
Rider’s Weight: Your weight and the bike’s weight has a tremendous impact on the dirt bike’s speed. The heavier your and the bike’s weight is, the slower you are likely to go.
Nature of Track: You are expected to ride faster on a paved flat surface than on long climbs and rugged roads. Look for a smoother track if you want to ride faster.
Weather: Bad weather slows down a rider as they have to ride cautiously. So, even if you have the fastest dirt bike, you cannot reach the top speed when the weather is terrible.
We cannot answer ‘how fast does a 250cc dirt bike go’ without comparing what would affect the top speed of a 250cc dirt bike. Now that we have done so, you know what to expect from your 250cc dirt bike.
