The term “500cc” refers to the displacement of the engine, not to its actual capacity in cubic inches. The 500 series has historically been used for 2-stroke engines and was introduced in 1959 by Kawasaki.
In the United States, it was known as the KZ series. It became popular with customizers and dirt bike racers due to the lower cost of running and maintaining an air/oil-cooled machine rather than a water-cooled one.
As such, it gained popularity among enthusiasts racing on public roads and off-road trails.
A 500cc engine produces approximately 15 horsepower (11kW) at 7,000 RPM.
This is about half the power produced by a 350 cc twin-cylinder motorcycle engine, but twice that of a 250 cc single-cylinder engine.
This article will discuss how fast a 500cc dirt bike can go, what makes them fast, how much fuel they use, and why you should consider buying one.
The Condition Of Your Bike Will Affect The Speed
Dirt bikes are great fun, but they also require a lot of maintenance. If you want to get the most out of your ride, you’ll need to take care of your bike properly. The first step is to check its condition.
A good way to start is to look at the tires. They should be inflated correctly and worn evenly. Next, check the brakes and suspension components. Finally, take a close look at the frame and engine.
Here’s what to do:
1. Look for cracks or dings in the frame. These can indicate serious problems with the frame. Cracks may show signs of weakness or corrosion. You may not notice them until you put some weight on the bike.
2. Are there any loose bolts? Loose nuts can lead to broken parts over time.
3. Check the chain tensioner, if it isn’t working well. A weak chain could cause damage to the drivetrain.
4. Check the front forks for play. Too much movement can contribute to premature bearing failure.
5. Is there excessive oil sludge around the engine? Excessive oil means that the engine is underperforming. When this happens, it’s usually because the oil pressure regulator isn’t working right.
The Engine Strength
While the condition of your bike will affect how fast it goes, the strength of the engine will have more impact. If the engine is too small, it won’t last long.
And even if it does work fine, you won’t be able to make full use of all the potential speed.
To understand where you stand, here are some numbers you might find useful:
• The maximum torque output of a typical 400, 450, or 500cc two-stroke engine is 18 ft-lbs (25Nm).
• An average 250cc four-stroke engine produces 25 ft-lbs (34Nm), while a dual overhead camshaft 300cc four-stroke engine achieves 35 ft-lbs (47Nm).
• An average 600cc V-twin produces 40 ft-lbs (55Nm).
Note that these figures only apply when the engine is new. Over time, the performance of the engine decreases and so does its durability.
How Fast Will A Dirt Bike Go?
Now that we’ve covered how fast a dirt bike can go, let’s talk about how much fuel it uses.
One thing to keep in mind is that the size of your bike affects how much fuel it takes to accelerate. For example, a 250cc bike will typically take less fuel per mile than a 500cc bike.
However, a 250cc bike requires more throttle input to achieve the same acceleration as a 500cc bike.
In general, larger engines consume more fuel per hour of riding. So, a 700cc bike will burn more gas than a 200cc bike.
However, the amount of power generated by an engine depends on many factors.
For instance, the type of motor used, the number of cylinders, and whether the engine has a single or twin cylinder configuration.
When it comes to dirt bikes, the size of the engine is often the main factor determining how fast they go. But, other features such as the gearing system also play a role.
Gearing systems determine the ratio between the rotational force produced by the crankshaft and the distance traveled by the rear wheel during one revolution of the crankshaft.
This relationship determines how quickly the rider can accelerate.
For instance, a high gear ratio allows faster acceleration, but it also makes it harder to stop.
On the other hand, a low gear ratio will provide better-stopping power, but it reduces the ability to get up to speed quickly.
So, what is the best gear ratio for a given situation? It really depends on how you plan to ride the bike.
You’ll need to figure out which gears give you the most control over the bike and which ones offer the best balance between speed and maneuverability.
But, whatever gear you choose, remember that the bigger the engine, the lower the ideal gear ratio. That means you’ll want to use a higher gear ratio than you would with smaller engines.
What About Fuel Efficiency?
Of course, the biggest issue affecting fuel efficiency is your weight. A heavy rider will always require more fuel to maintain the same speed.
Also, heavier riders tend to pedal slower because they don’t have the same level of leverage when pushing down on the pedals. As a result, they’re not using their legs as efficiently as lighter riders.
Other things like the terrain, wind resistance, and the vehicle itself also contribute to fuel consumption.
Frequently Asked Questions
In this section, we are going to answer some of the most frequently asked questions concerning 500CC dirt bikes and how fast they are. So, let’s get started!
Who Makes 500CC Dirt Bikes?
The first question people usually ask is who makes 500CC dirt bikes. Well, there are three major manufacturers of 500CC dirt bikes: Honda, Kawasaki, and Suzuki.
Honda produces two different models of 500CC dirt bikes; the CBR500R and CRF450R. The former is designed for off-road use while the latter is designed for road racing.
Kawasaki produces only one model of 500CC dirt bike; the ZX-6R. They make the ZX-10R for off-road use and the ZX-14R for racing.
Finally, Suzuki builds both the GSX-S750 and the GSX-S1000. Both these bikes are aimed at racers and feature very similar specifications.
However, you should know that none of the four companies mentioned above build all of their own bikes in house. Instead, they buy them from outside manufacturers.
Did They Stop Making 500CC Dirt Bikes?
Another common question is whether the manufacturers stopped making 500cc dirt bikes. In fact, the answer is no. All four manufacturers still produce 500cc dirt bikes today.
The problem is that the market for small displacement motorcycles has shrunk substantially. Therefore, it’s getting much harder to find an affordable 500cc dirt bike.
It’s important to keep in mind that the demand for 500cc dirt bikes is actually quite strong. However, it’s simply hard to meet that demand due to the limited supply.

Can I Get Good Gas Mileage Riding A 500cc Dirt Bike?
If you’ve ever ridden a motorcycle before, then you probably already know that good gas mileage requires a lot of work.
To start with, you must be able to shift the transmission correctly. This involves learning how to move the clutch lever into neutral, up shifts, and downshifts properly.
Then, you must be able to switch back and forth between manual and automatic transmissions. Finally, you must master shifting through multiple gears without stalling the bike.
This can take years of practice to achieve. Even if you do manage to perfect all those techniques, you’ll never get close to the best possible gas mileage unless you change the way you ride.
So, what does this mean? It means that the best possible gas mileage cannot be achieved by riding a 500cc dirt bike constantly.
Instead, you need to adapt your riding style to maximize the amount of time you spend on the throttle. You need to be able to accelerate quickly when needed and decelerate slowly when possible.
You also need to be able to maintain speed at high speeds and stop smoothly without skidding the rear wheel.
In short, you need to become a better rider so that you can maximize the number of miles per gallon that you get.
