How Much Horsepower Does a Dirt Bike Have? (With 20 Examples)


how much horsepower does a dirt bike have

How much horsepower does a dirt bike have? This is the question that you will come across from time to time. First of all, you need to understand what the term ‘horsepower’ refers to as far as dirt bikes are concerned.

Horsepower (HP) takes into account the amount of force with the rate at which the same force is applied.

In circular motion (radial motion), horsepower is the direct result of rotations per minute (rpm) and torque.

On the other hand, torque is the amount of rotational force at a given distance.

So, by taking torque and rpm into consideration, you can easily work out the horsepower of your dirt bike engine.

Here is the general formula you can use:

Horsepower (HP) = Torque x RPM/5252

At 5252 rpm, both the torque and horsepower should be equal.

When you represent these parameters on a graph, torque versus horsepower lines must intersect at 5252 rpm.

This brings us to the question as to why 5252 is a constant in this regard. Apparently, HP is defined as 33,000 lb-ft per minute.

Keep in mind that a one-foot circumference radius circle is approximately 6.2832 feet.

Since these are constants, you may divide 33,000 by 6.2832 to obtain 5252. This is how 5252 constant comes about.

Both the horsepower and torque are important measurements when it comes to your dirt bike engine.

So, how much horsepower does a dirt bike have? Let’s find out from below examples of 20 best dirt bikes on the market today.

Top 20 Dirt Bikes and Their Respective Horsepower

Before you set out to look for your dream dirt bike, it is important to know the type of riding you are looking forward to.

There are two major differentiations in dirt biking; trail riding and motocross riding.

Trail riding is meant for you if you are an adrenaline junkie looking to traverse the most challenging terrain you can think of.

This type of riding involves hundreds of miles on rugged trails, hills, jungles, and swampy areas.

Unlike the motocross riding, trail riding is unpredictable and gives you the liberty to choose your own path.

This ride is more of a measure of your capability rather than racing against time or an opponent.

When it comes to motocross, the situation is a little bit different. Here you only race on a groomed outdoor track.

The race involves several laps on a predetermined course where variables are already set.

So what is the average horsepower of dirt bikes?
