customized Harley-Davidson Softail Fat Boy

Power & Beauty!


This Harley-Davidson Softail Fat Boy called the Black Dog is the epitome of power and beauty, and at first glance, its dark appearance is striking. The name Black Dog is perfect for this bike because the black and blue paint and aggressive lines make it look like a wild dog ready to take on the road.

A black dog (also called a black hound) is a character from British folklore described as a ghostly being.

It is said to appear mainly at night and is often seen as a harbinger of death. Unlike a normal dog, the black dog is usually larger and has eerily glowing eyes.

There are many theories about what the Black Dog symbolizes. Some believe that it is a manifestation of depression or fear, while others believe that it is a kind of guardian spirit that protects people on their journey.

The Big Speed wheels mounted on the Black Dog keep their promise. The milled 5-spoke aluminum wheels in 23″ front and 21″ rear (original: 18/18″) and the Metzeler ME 888 all-round tires in 130 and 260 mm width (original: 160/240 mm) give the bike a sporty character.

The Black Dog is equipped with the powerful Milwaukee Eight 114 engine that delivers impressive performance right out of the box. The front and rear air suspension allows the Black Dog to be lowered quickly and the balanced combination of chassis, wheels and tires provides for good handling.

The lucky owner brought the base bike for the extensive conversion on his own wheels from England and did not miss to pick up his custom bike personally and get it handed over by Julian. What a great moment!

The bike was also equipped with our Hollywood Light handlebars with old style risers and a steel fender. The Jekyll and Hyde exhaust system with short exhaust pipes completes the design and gives the bike the typical roaring sound of the powerful Milwaukee Eight engine. All in all, the Black Dog is a bike that immediately catches the eye and cannot be overlooked.


The Black Dog has conversions like the Road Force 3.0, the Red Force and the Black Apple as a model. You like this style? We can customize it for you and build your own power on two wheels.
