Ice-cool Brother

Black Soul


If you like it a little sportier …

we recommend a conversion in our GT style! What makes this style? Power, a sporty chassis and a sporty look! So: With a lot of power thanks to Milwaukee-Eight 114, Screamin’ Eagle Stage II and the DON Performance Mapping, the inner values of this Softail FXDR are already right.

Visually, the GT-4 scores with our body parts, an exclusive Kruse paint job and various covers and coatings. Chassis-wise we have lowered the FXDR, her our new suspension system Slamtail and the fancy wheels from our New Digger series. The rear with the seat pan is bolted on like our GT style.

We achieve the crouched stance despite the larger wheels in 23 and 21 inches by the Slamtail at the rear and by lowering the fork, our triple clamp and the stub handlebar.

The acoustic pleasure and the last peak performance comes in this case by the Heavy Breather Elite from Harley-Davidson and the exhaust from Kess Tech.

Some other parts from the Thunderbike production, such as the pre-mounted footrest system, grips and toppers, as well as the side license plate complete our concept.

As you can guess from the name of the bike, there are other conversions in this vein. Originally based on the FXDR, we continue to build the GT series with the Breakout. The special parts that make up this style are compatible with both models.

By the way: If you are interested in the other bikes of this series and the making-of, you should have a look at the feature about our GT-3. Here we have welded the rear fender from tens of individual parts, but the rest of the conversion was very similar. Because she was one of the role models.
