Big Force

customized Harley-Davidson Softail Fat Boy 114

The imposing powerhouse

The Milwaukee Eight Fat Boy with the 114cc engine provides an ideal base for our Force series, which is growing in popularity.

The Big Force is one of the newest specimens in this collection.

As with its predecessors, we have made a point of preserving the typical Fat Boy features, such as tank and fork fairing, in their original form. So that it is still recognizable as a Fat Boy even after its custom cure. But that’s all that remains untouched, otherwise it has the change and ingredients list in itself.

The whole bike, including the engine, is completely disassembled and all chrome parts are powder-coated black. The chassis gets a single-sided swingarm, as well as an Aride system front and rear, with which the bike can be conveniently lowered and raised. We combine our multi-piece Big Speed wheels in front 23″ and rear 21″ with close-cropped fenders to really show off their size. The nose spoiler enhances the Big Force’s compact appearance. The forward-mounted footpeg system, in combination with the apehanger, ensure a relaxed riding position that makes it easy to master every corner.

The glossy paint finish comes once again from Kurse Design. With his graphics, Ingo always knows how to bring the whole concept to the point.

The Big Force runs the first kilometers in Faak, at the European Bike Week.
