Dirt bikes are becoming very popular these days. They are also known as motocross bikes or MX bikes. 

They are often designed specifically for off-road riding and are usually powered by two-stroke engines (but there are dirt bikes with a four-stroke engine as well) and come equipped with large tires.

What Is The Fastest Dirt Bike?

Furthermore, these powerful dirt bikes are often seen racing at tracks such as Motocross Raceway Park in California. These bikes are built to withstand extreme conditions and are capable of speeds of over 100 mph.

In this article, we’re going over some of the fastest dirt bikes ever made and taking a a closer look at what bike features make them so fast.

Fastest Bikes

The fastest dirt bike is the Suzuki RMZ450 which can reach a top speed of around 225 km/h (140 mph).

This powerful dirt bike was built for the 2011 AMA Supercross Championship, but it failed to make an appearance due to technical problems.

The Honda CRF250R is the current world record holder for the fastest production motorcycle, reaching a top speed of 199.5 km/h (124.7 mph) on a closed course in Germany.

This has been achieved by riders like Valentino Rossi and Max Biaggi.

The Kawasaki ZX6R is the fastest production bike ever ridden on public roads, with a top speed of 210.2 km/h (130.4 mph), set by American rider Mike Metzger.

It’s important to note that the fastest dirtbike doesn’t always mean the best one.

Some dirt bike riders prefer the handling characteristics of smaller motorcycles while others enjoy the power of bigger machines.

So, before you buy your next dirt bike, consider all the factors involved.

What Makes A Dirt Bike Fast?

There are many things that contribute to making a dirt bike fast, and it’s a little more complicated than you might think.

For example, it’s one thing going fast in a straight line on a tarmac road, but it’s another thing to get around a dirt race track as fast as possible.

Let’s take a closer look at some of the most important factors when it comes to dirt bike speed:

1. Large Tires

Large tires help increase traction and grip when driving through loose terrain. They also provide better stability than small tires.

2. High-Performance Engines

High-performance engines produce more horsepower and torque. This allows riders to get up to higher speeds and go faster.

3. Lightweight Frame

A lightweight frame helps reduce weight, which means less drag and increased acceleration.

This doesn’t really equate to a higher top speed, but it will certainly get you around a course much quicker.

4. Low Center Of Gravity

A low center of gravity reduces the amount of force required to accelerate the vehicle forward. This results in a smoother ride and improved handling.

5. Suspension Setup

Suspension setup plays a big role in how fast a bike will be able to go. If the suspension is too soft, then the bike will not handle well.

On the other hand, if the suspension is too stiff, then the bike won’t have enough travel to absorb bumps and rough terrain.

6. Brakes

As counterintuitive as it seems, brakes play a huge role in how fast bike or any vehicle can get around a race track.

Whether it’s a car or a dirt bike, brakes need to work properly to get the vehicle around corners smoothly and efficiently.

7. Tire Pressure

Tire pressure affects how much contact area there is between the tire and the ground. Too high tire pressure can cause the tire to wear out prematurely and lose its ability to grip.

8. Aerodynamics

Any high school physics teacher will tell you how important aerodynamics are for determining how fast a dirt bike can go.

Air resistance is the force that acts on a moving object in the opposite direction that it’s moving in.

The aim of racing vehicle mechanics is to reduce air resistance as much as possible using aerodynamic designs.

This isn’t as prominent with dirt bikes as it is with cars, but it’s still something that manufacturers think about.

How To Choose A Dirt Bike

How To Choose A Dirt Bike

Choosing the right dirt bike for you depends on what kind of riding you want to do.

You may only want to use your dirt bike for trail riding, or maybe you’re interested in competing in off-road races. Whatever your needs are, make sure the dirt bike category matches the type of riding you plan to do.

If you’re looking for an all-around bike that does everything from trail riding to motocross, then you should consider buying a dual-sport motorcycle.

Dual sport motorcycles feature two different types of suspension systems. These include a hard front end and a softer rear suspension.

Dual sport bikes are great for those who like to explore trails because they offer both comfort and control. However, these bikes don’t perform very well on pavement due to their lack of suspension.

If you want to buy a dirt bike specifically designed for trail riding, then you’ll want to look at a full-suspension mountain bike.

Full-suspension mountain bikes feature a long wheelbase and large wheels so that they can better withstand jumps, drops, and rough terrain.

Full-suspension mountain bikes also tend to weigh more than dual sport bikes because they require more material to build them.

They also cost more money than dual sport bikes.

If you prefer to ride on hard-road surfaces, then you might want to choose a road bike instead. Road bikes usually come equipped with drop bars and disc brakes.

Road bikes are lighter than full-suspension mountain bikes and cheaper than dual sport bikes.

But they aren’t as comfortable as full-suspension mountain bikers when it comes to handling over rough terrain.

Dirt Bikes For Beginners: Buying Guide

Buying a dirt bike for beginners isn’t quite as simple as buying a new pair of sneakers. There are many factors that determine which model of dirt bike is best suited for you.

1. Frame Material

Frame material has a big impact on the performance of a dirt bike.

If you’re looking for a beginner’s dirt bike, then you should avoid frames made out of steel. Steel frames are heavy and not very durable.

You should also steer clear of aluminum frames if you’re planning on taking part in any competitions. Aluminum frames are light and easy to maintain, but they wear down quickly.

On the other hand, titanium frames are extremely lightweight, strong, and durable.

Most people opt for titanium frames because they feel like they have a smoother ride compared to other materials.

2. Suspension System

The type of suspension system you get will depend on how often you plan on riding. If you plan on doing lots of jumping and dropping, then you need a frame that features a lot of travel.

This means that the suspension system on this bike will be able to absorb a lot of bumps and shocks.

On the other hand, if you just want to take some short rides around town, then you won’t need much suspension.

3. Brakes & Wheels

Brakes are one of the most important parts of your dirt bike. You need good brakes to stop safely and easily.

Good brakes will prevent you from crashing into things or getting stuck in mud. Good brakes will also help you stay upright while riding through curves and turns.

Wheels are another thing that you need to consider before purchasing a dirt bike. A set of tires that fits your frame perfectly is an essential component of a good dirt bike.

4. Handlebars & Seatpost

Handlebars are one of the first things that you notice about a dirt bike. This is because handlebars dictate how far back you sit.

Seatposts are another important factor to consider when choosing a seat. Some seats are adjustable, while others are fixed. Fixed seats are easier to adjust, but they don’t offer as much comfort.

5. Tire Size

Tire size is something else that you need to think about when you’re buying a dirt bike. Smaller tires are better for tight trails, while larger tires are ideal for open roads.

6. Motor

Motor power is another important aspect to consider when you’re buying a new dirt bike. High-powered motors can make long distances seem shorter.

However, it’s important to remember that higher-powered motors are also more difficult to control. Therefore, they might not always be the best options for beginners.

7. Accessories

There are many accessories available for dirt bikes. These include lights, fenders, racks, etc. Getting a dirt bike with plenty of accessories included can prove to be pretty great value for money!


Buying a dirt bike isn’t always about finding the fastest one, but this is often the thing we’re most interested in.

Just remember that speed isn’t solely dictated by engine size or power and that there are a multitude of different factors that also come into play.

If you’re looking to get the fastest and most powerful dirt bike that you can possibly handle, follow the tips we’ve outlined in this article to get the best option for you!
