The “Diablo” is a fully customized Harley-Davidson Night Rod brought to life by Fiber Bull, a custom workshop based in Spain known for their radical and high-impact designs.

This build commands attention from every angle — and it starts with the massive rear wheel that defines the bike’s brutal silhouette. The oversized tire isn’t just for show — it gives Diablo a powerful stance, pushing the boundaries of V-Rod customization while preserving the aggressive DNA of the original model.

The bodywork has been completely reimagined. Finished in a striking white with bold black accents, the bike features a minimalist rear fender, integrated LED lighting, and a sculpted custom tank that proudly bears the name “Diablo” in oversized lettering.

Every detail has been designed with precision: custom handlebars, upgraded exhaust system, and blacked-out performance components that give the bike a stealthy, muscular look. The side-mounted license plate and the double exhaust tucked under the frame add to the bike’s streamlined, powerful profile.

Fiber Bull has created a Night Rod that truly lives up to its name — Diablo is a devilish mix of style, attitude, and raw mechanical presence.

The Harley-Davidson V-Rod has long been a symbol of raw power and modern design in the world of custom motorcycles.

But in the hands of Spanish custom shop FiberBull, this V-Rod has been completely transformed into a dark mechanical beast that perfectly blends aggression, precision, and style.

This stunning machine, dressed entirely in black, showcases FiberBull’s signature touch — a low and muscular stance, wide rear tire setup, and a clean, minimal tail section. The exhaust system is particularly striking, wrapped and routed in a way that emphasizes the brutal character of the Revolution engine. Every detail, from the front inverted forks to the sharp bodywork and handcrafted seat, speaks of hours of dedication and craftsmanship.

What truly sets this V-Rod apart is its attitude. It’s more than a motorcycle — it’s a statement of dominance and design. The build respects the original DNA of the Harley-Davidson V-Rod while pushing it into a new realm of custom culture.

FiberBull has once again proven that Spain is home to some of the most innovative custom bike builders in Europe. This project is a fine example of how artistry and performance can coexist in perfect harmony.

This beast of a bike stands out in a vibrant yellow hue, an eye-catching color that commands attention on the road.

Under the hands of Fiber Bull, ‘Mustard’ has undergone an impressive transformation, boasting modifications that truly set it apart from the rest. The most striking feature? A super wide 330 wheel that not only enhances its appearance but also ensures a solid grip on any terrain.

Mustard doesn’t just rely on looks—it’s equipped for safety and visibility too. The addition of the Future Lighthouse ensures a clear path ahead, while turn signals with position and brake lights keep it visible on the road.

But it’s not just the wheels and lights that got an upgrade. The complete custom bodywork gives Mustard a unique silhouette, turning heads wherever it cruises.

The custom 1-seater seat provides a personal touch. Riding comfort meets adaptability with the air suspension, allowing for a smooth journey regardless of the terrain.

And what’s power without an impressive roar? The 2in2 black exhausts deliver just that, giving Mustard the voice to match its bold appearance.

Even the practicalities haven’t been overlooked—the license plate support relocation adds to the sleek design, maintaining legality without compromising style.
