The Harley-Davidson V-Rod ‘Hulk’ is a striking muscle custom created by Bündnerbike, inspired by the historic collaboration between Harley-Davidson and Porsche in the development of the Revolution engine.

Finished in an unmistakable green tone, this custom build earns its nickname “Hulk” thanks to its powerful stance, aggressive proportions, and overwhelming visual presence.

This Porsche Edition V-Rod stands out for its wide rear tire, low-slung profile, and perfectly balanced lines that emphasize brute force and precision engineering.

The minimalist bodywork highlights the muscular character of the bike, while the modern components, blacked-out mechanical parts, and compact exhaust system reinforce its performance-oriented identity.

Every detail is designed to convey strength, speed, and exclusivity.

More than just a custom motorcycle, the V-Rod “Hulk” represents a fusion of American muscle and German engineering philosophy.

Bündnerbike transforms the original platform into a bold statement piece that blends raw power with refined design, making it a true icon within the world of high-end Harley-Davidson muscle customs.

The Harley-Davidson Night Rod ‘Bad Habitz’ is a stunning custom motorcycle built by Bozzies in the Netherlands and proudly owned by FM Car Treatments.

This unique build draws inspiration from Porsche design, combining raw American power with the refined lines and precision of European engineering. The result is a machine that looks as fast as it rides — bold, muscular, and beautifully balanced.

One of the most striking features of “Bad Habitz” is its massive wide rear wheel, giving the bike a powerful and aggressive stance. The exclusive hand-crafted paint, with a carbon-style finish, highlights the custom bodywork and adds a high-performance aesthetic that perfectly matches its attitude. Every line, curve, and texture reflects meticulous attention to detail.

The 2-in-2 black exhaust system not only enhances performance but also delivers a deep, brutal sound that commands attention wherever it goes. Complementing the setup is a custom-made seat, designed for comfort and control, while maintaining the clean, low-slung silhouette that defines this V-Rod’s character.

Every aspect of this motorcycle — from its engineering to its visual impact — represents the artistry and technical skill that define Bozzies’ work. “Bad Habitz” isn’t just a custom Harley; it’s a statement of individuality, precision, and passion for perfection.

We would like to introduce you to a very special duo: the Porsche 911 GT3 RS with the Weissach Package, and the custom Harley-Davidson Softail Breakout built to match it: the Thunderbike GP-Weissach.

Together with our customer Stefan, we created a project that bridges the gap between high-performance automotive engineering and handcrafted custom motorcycle design. This is not our first collaboration with him. Nearly ten years ago, Stefan inspired one of our most iconic builds, the Lamborghini Aventador–themed Thunderbike OUTERLIMIT. Now, the story continues with a new interpretation of power, precision and style.

The inspiration for the GP-Weissach project comes directly from Stefan’s Porsche 911 GT3 RS (992.1), a machine that represents the ultimate track-focused driving experience. Its 4.0-liter naturally aspirated engine delivers 525 hp, accelerating the 1450 kg car from 0 to 100 km/h in just 3.2 seconds. The Weissach Package further enhances performance by reducing weight by around 15 kilograms through targeted lightweight construction.

Visible high-gloss carbon components such as the front hood, roof, exterior mirrors and wing elements emphasize the motorsport character. Inside, the combination of Race-Tex upholstery, red contrast stitching, magnesium shift paddles and carbon fiber surfaces reflects a pure racing atmosphere. Even the magnesium wheels finished in Pyrored inspired the key color accents of our motorcycle.

For the bike, we selected the Harley-Davidson Breakout FXBRS with Milwaukee-Eight engine as the foundation. This model offers the ideal frame geometry to integrate our GP rear conversion and the substantial 9×21-inch rear wheel. The cockpit retains the original digital speedometer but is now seamlessly integrated into a custom-milled triple clamp. The goal was not to copy the Porsche, but to interpret its attitude. Colors, proportions, finishes and materials were chosen to translate the GT3 RS design language into a new aesthetic expression on two wheels.

The GP-Weissach incorporates the latest developments from our high-end GP component line. It features aerodynamically optimized triple clamps, redesigned handlebar mounts with Rebuffini RR90 controls, and a new GP front mask, all contributing to a dynamic and athletic stance. The open primary drive adds mechanical transparency and highlights the powertrain.

The single-sided swingarm, milled from a solid block of aluminum, allows an unobstructed view of the wheel. An air suspension system at the front and a hydraulically adjustable rear setup lower the bike when parked, giving it a dramatic, grounded presence.

A defining aspect of the design is the use of Pyrored accents, directly referencing the Porsche’s wheel color. The wheels of the GP-Weissach are milled from a single piece, then selectively machined after anodizing to create depth, sharp edges and visual motion. Their five-spoke Y-design appears lightweight and technical, perfectly matching the sporty and high-end character of the build. The exposed 21-inch rear wheel, combined with the perimeter brake system, serves as both a functional and visual centerpiece that underscores the precision and craftsmanship of the motorcycle.

At the end of the project, Stefan summed up his feelings in one sentence: “My goal was 100%. You delivered 110%.” For us, that is the greatest recognition. The GP-Weissach is more than a custom motorcycle. It is the translation of supercar performance philosophy into hand-built motorcycle culture. A Porsche created for the racetrack, and a Harley reinvented to share its spirit. Two machines, one shared heartbeat of motorsport passion.

Cult-Werk has once again pushed the limits of custom motorcycle design with their latest creation: a Harley-Davidson V-Rod transformed into a stunning tribute to the legendary Porsche Rothmans racing livery.

This build is a perfect fusion of power, precision, and motorsport heritage, paying homage to Porsche’s dominance in endurance racing.

The bike’s aesthetics are immediately striking, featuring the iconic Rothmans blue, white, and red color scheme with gold accents that mirror the livery of the legendary Porsche race cars. Every detail, from the custom paintwork to the refined bodywork, has been meticulously crafted to exude speed and elegance.

Underneath its aggressive exterior, this V-Rod retains its high-performance DNA, now enhanced with a series of premium modifications. The blacked-out engine and exhaust system add a menacing contrast to the vibrant fairings, while upgraded components ensure that this machine is as fast as it looks.

The seat, tailored to perfection with quilted detailing and Rothmans branding, provides both comfort and style. Additional touches such as the aerodynamic fairings and gold-rimmed wheels elevate the overall aesthetic, making this bike a true collector’s piece for both Harley-Davidson and motorsport enthusiasts.

Cult-Werk’s Porsche Rothmans tribute V-Rod is more than just a custom build—it’s a statement of craftsmanship, performance, and passion. A true icon reborn, this motorcycle bridges the gap between Harley-Davidson’s muscle and Porsche’s racing legacy, creating a ride that is as exhilarating as it is visually stunning.
