From the time the first gasoline engine was fitted to motorcycles, guys have been adapting their bikes for offroad use.

Taking off parts like lights and horns, adding knobby tires and better suspension, no one man was credited with who made the first dirt bikes.

In 1885 Daimler and Maybach created a motorcycle that was different to what had come previously.

In 1914 Siegfried Bettman modified existing Triumph models to make something that resembled more of a dirtbike than Daimler and Maybach.

Who made the first dirt bikes? By the late 1950's, early 1960's Honda was developing motorcycles that were more mainstream.
