The first motorcycles were produced by companies like Indian, Harley, BSA, and Norton. And since in the early 20th century there were a lot more dirt roads than there were paved roads, these motorcycles were designed to be riden on the dirt as well as the paved roads. Making Matchless the first company to produce a dirt bike in 1899.

As a modern dirt bike goes, it seems that the earliest reverence I can find is a 1924 Velocette. It was used in the first motocross event known as a "Scramble" in Camberley, Surrey in southern England. There were probably other bikes used in this race, but you might be able to find more information with this race. But by the 1930s BSA, Norton, Rudge, Matchless, and AJS all made bikes to be used in the Scramble, so any of these bikes could be the first dirt bike, I just couldn't find any mention of them in the first Scramble. However as far as motorcycles used offroad, the 1914 Triumph Model A was used by the British Army as an offroad vehicle during WWI

Most of the first motorcycles made were basically bicycles with an internal combustion engine strapped on somehow. These bikes were constructed just as "roads" were beginning to appear, so they were built to ride off road as well. Therefore, even the first motorcycles could be referred to as "dirt bikes". So dirt bikes (and street bikes) have been around since the dawn of motorycling, just at the time they were simply considered regular motorcycles.

So no one person invented the dirt bike. People began to modify their bikes to ride in the dirt, starting with knobby tires and better suspensions, changing gearing/sprockets, frames, doing everything possible to lighten and strengthen them, getting rid of parts not needed in dirt riding (lites, horn, etc.).

One of the first motorcycles designed specifically for offroad use was by Sigfried Bettmann of Coventry, England. The company name was Triumph Motorcycles and the year was 1914.

This would be easier to answer if you had stated what type of early dirt bike you were looking for, like "First motocross, supercross, enduro ect." Or "what is the first dirt bike made by Honda, suzuki, or Kawasaki?"

I will answer this the best I can with such an open-ended question.

I deleted the DUCATI answer because it was too far from the truth to even leave up. Ducati was founded in 1926, two years after the first off-road race. They did not start producing motorcycles for another twenty-four years.

The greatest of all time Keith,Parrish, and Ricky Carmichael

Actually Keith, Parrish, and Rivy Carmichael are just a few of the best, you left out Chad Reed and Bubba Stewart. But they just made it better. :) Being serious, a Japanese guy named Soichiro Honda opened a little motorcycle shop in LA, Calif. and he started sell them. dirt biking is where you ride a bike with a motor on it and it makes it go fast and you can do tricks and and things like that and t is a blast.

hahahahahaha
united states of America duhhhhh
It was invented in Kyle Crammer factory
I think in Germany or England.
If a two-wheeled vehicle with steam propulsion is considered a motorcycle, then the first one may have been American. One such machine was demonstrated at fairs and circuses in the eastern U.S. in 1867, built by Sylvester Howard Roper of Roxbury, Massachusetts.
