It is not always easy to discover who first came up with the idea of something. Some inventions get attributed to certain individuals, even when someone else was the first one developing the idea.

This applies in any business or industry, even to the automotive one. Indeed, the scramble to innovate, to out-compete competition, and to create something new is real in the field of transportation. Most of the time, new inventions are based on something that already exists and that is improved or evolved for the better.


For example, talking about motorcycles, as soon one was invented, some riders begin to modify it, improving the tires for more traction or suspension. While it is still not very clearly who invented the dirt bike, there is information out there suggesting that Soichiro Honda was who we should attribute the invention of this type of motorcycle.

But, the reality can get a bit more complex than that. Indeed, it seems that Honda did help to popularize the model in the 1950s, but that the first dirt bike can be dated much earlier than that. If you want to learn more about dirt bikes and their invention, keep reading this article. We put together all the information we found to give you a clear picture of the invention of this motorcycle.

So, who really invented the dirt bike?

Short answer:

The first dirt bike is assumed to be invented in 1914 by Siegfield Bettman. In order to make motorcycles more versatile for off-road use, Betmann used to modify them. However, it was only until the 1950s that those bikes started to become popular, thanks to Soichiro Honda’s efforts in bringing them to the market.

The most notable inspiration for the modern-day dirt bike can be attributed to two German inventors: Daimler and Maybach, they gasoline-powered motorcycle was called Reitwagen, which can be translated from German to “riding car”.

Despite this, the first real dirt bike is assumed to be created in the early 1910s by Siegfried Bettmann. He used to take motorcycles that were already in the market to change their design and improve their usability.

He was working for Triumph in 1914 when he modified some motorcycles to create a new model. However, those bikes started to get popular in the 1950s, thanks to Honda’s efforts in bringing them to the market.

Bettmann did try to bring it on the market but because his adjustments weren’t performing so well, his bike did not become so popular. To make the bike more versatile for off-road use, he decided to lower the bike to the ground and performed some other tricks on the suspensions, which were unfortunately unsuccessful.

Honda CRF250R

Before Honda

Even though there was not much evolution between 1914 and the 1940s in terms of dirt bikes, it was between the 1940s and the 1950s, when these types of motorcycles started to take off. It was during these years that dirt bikes started to be manufactured from scratch and stopped being simple modifications of street bikes.

The concept behind the common dirt bike was to create a versatile motorbike that would perform well both on dirt and pavement and roads. Keep in mind that most roads were still unpaved when the first motorized bicycles appeared, so it was important to create models that could be easily used on any kind of terrain.


Soichiro Honda

Honda is the first company that started to manufacture dirt bikes on a big scale and that made them popular. It transformed this vehicle into something mainstream, especially during the 1950s and 1960s.

They managed to modernize the models of dirt bikes available at the time and make them accessible to everybody. Thanks to the addition to the stronger suspension, bigger tires and better tractions, their model quickly become popular. Even if Honda was not the inventor of the dirt bike itself, the improvements brought by Honda did make a huge impact on the popularization of dirt bikes.

Yamaha Dirt Bike


Others believe that Yamaha, a company that started out creating products very different from motorcycles, should be attributed to the invention of dirt bikes as we know them today. While producing their first bike only in the mid-1950s, which is much later compared to other companies, Yamaha was a real innovator in the industry.


Indeed, they revolutionized the sport of motocross racing by introducing the DT-1 bike in the 1970s. Such a model was designed to be ridden in any kind of terrain and because of its great performance and success, it quickly became the standard upon which the next dirt bikes were created.

These days, Yamaha is one of the best iconic dirt bike brands. My fellow riders consider the Yamaha dirt bikes as one of the best in the world by winning in different dirt bike categories.

KTM dirt bike

Suzuki, Kawasaki, and KTM

We talked about companies and individuals associated with the invention of the current dirt bikes, but brands like Suzuki, Kawasaki, and KTM are also important names in the industry of dirty bikes today whose evolution is worth mentioning.

Suzuki started creating motorcycles during the Second World War, to supply people’s need for a smaller and lighter means of transport. Their first models were old bikes equipped with a 36cc 2-stroke engine. It was only by the late 1950s that they started bringing dirt bikes to the market.

Before manufacturing motorbikes, Kawasaki was an important air manufacturer, active during both World wars. In 1949, they created their first motorcycle and their first dirt bike only came out in 1963.

KTM was founded in 1934, Mattighofen Austria

KTM started gaining popularity only during the 1970s, even though they started selling motorcycles long before that. Today, this company is considered one of the best in the market, especially for high-performance dirt bikes. Their bikes are the lightest on the market and have consistently dominated the enduro scene for years now.

KTM owns the following dirt bike Brands

  • KTM
  • Husqvarna Motorcycles
  • GasGas

Today, dirt biking is a billion-dollar history, but it hasn’t always been like that. It can be interesting to be aware of dirt bike’s evolutions and to realize that their invention can largely be attributed to the modification and adaptation of common motorcycles. While many actors did play a role in the invention of the first dirt bikes, in the end, it is just a few that get recognized for their efforts. While it can seem unfair, unfortunately, this is how things often work in life.
