Road Force 3.0

customized Harley-Davidson Softail Fat Boy

A real force on two wheels!


Our handmade steel fender with turn signal/tail light combo, the single-sided swingarm and the large alloy wheels from our machines and on top a terrific paint job by Kruse Design – these are the main actors in this conversion, which is based on the Softail Fat Boy. We like to call this type of conversion “Road Force” – a force on two wheels, made for the road.

The 114er Milwaukee-Eight engine with its 155 Nm torque brings its brute power over our Pulley on the Big Speed aluminum wheels. These sporty 5-spoke wheels in 21 and 23 inches (orig. both 18 inches) are just as created in our own production in Hamminkeln as the aluminum single-sided swingarm.

The rear is completed with the 260 tire (orig. 240 mm), by our steel fender with integrated lighting and the side license plate on the left side. Looking from the right, the rear wheel appears in its full glory through the shortened manifolds with the Dr. Jekill & Mr. Hyde exhaust. At the lowered front, the Flip II handlebars on the oldstyle risers ensure that the rider always has his bike under control.

Once again, Ingo Kruse puts the crown on the project. He did his paint job perfectly in an exceptional matte vintage green with a few shiny accents. Various covers and the powder-coated engine round off the equally chic and sporty appearance.
