The team at Thunderbike has once again unleashed their creativity on a Harley-Davidson Softail Fat Boy, delivering a build that is nothing short of a royal masterpiece.

The customer wanted something truly special, and Thunderbike delivered — dressing this beast in a bold and majestic Royal Purple finish.

Purple, long associated with royalty and nobility, is no coincidence here. This bike made its debut at the Custombike Show in Bad Salzuflen and instantly captivated everyone in the room. Now, it’s forever immortalized under the name Royal Purple.

The true highlight of this build lies in its wheels, crafted using a newly developed manufacturing technique. They resemble Thunderbike’s 25th Anniversary design — monoblock wheels milled from solid aluminum — but with a twist. These aren’t just classic two-tone finishes; their surfaces shimmer in a full spectrum of colors, especially impressive on the 9-inch wide, 21-inch rear wheel.
