Diamond Atelier has side stepped the traditional custom motorcycle scene with the DA#22 ULTRON, a one-of-a-kind machine that the Munich-based workshop describes as the world’s first hyperbike. Publicly revealed at the 2026 Goodwood Festival of Speed, the road-legal prototype is designed to narrow down the gap between high-performance superbikes and exclusive hypercars.
Rather than modifying an existing motorcycle with premium components, Diamond Atelier began the project by creating a completely new design language before engineering the mechanical package around it. Powering the DA#22 is KTM’s proven 1,301cc LC8 V-twin engine sourced from the 1290 Super Duke. Tuned to produce more than 205 horsepower, the engine delivers performance that places the motorcycle firmly in superbike territory.

Complementing the potent powertrain is a specially developed suspension package from Wilbers, featuring a TYPE 46 RR front fork inspired by World Superbike technology and a bespoke rear shock tailored specifically for the compact layout of the project. Every major component was selected to ensure that the motorcycle remains serviceable despite its unconventional packaging. The most striking feature of the DA#22 is undoubtedly its handcrafted aluminum bodywork. Every panel was individually shaped by Marvin Diehl of KRT Framework over a period exceeding 800 hours.
Instead of exposing the motorcycle’s mechanical components like a conventional naked bike, the sculpted aluminum shell forms a seamless surface with dramatically shortened proportions, a floating tail section, hidden electronics, and a cockpit concealed beneath a recessed glass panel. The design gives the motorcycle an unmistakable silhouette that looks unlike any current production model. Diamond Atelier also incorporated advanced manufacturing techniques throughout the project. Several key components, including the titanium exhaust system and the upper triple clamp, were produced using 3D printing by Aconity3D. Formula 1-inspired switchgear, an illuminated clutch cover with a glass inspection window, and precision-machined controls supplied by specialist partners further reinforce the machine’s premium engineering.
Even the upper triple clamp features a genuine diamond mounted in sterling silver, serving as a subtle reference to the company’s name rather than a purely decorative addition. Perhaps the most innovative element is the motorcycle’s unique electroluminescent paint. Developed exclusively for the prototype by Alex Bloch of Stilbruch Lack, the special coating emits a deep red glow when an electrical current is applied, allowing the bodywork itself to become the light source without relying on external LEDs. According to Diamond Atelier, only a single liter of this custom paint formulation was ever produced, and the entire batch was used on the DA#22, ensuring the finish can never be exactly replicated.
Although the DA#22 remains a prototype, Diamond Atelier sees it as the beginning of an ultra-exclusive series that explores new possibilities in motorcycle design. Combining handcrafted coachbuilding techniques and extreme performance, the bike a fresh interpretation of what a flagship motorcycle can be. Rather than simply chasing speed or luxury alone, it demonstrates how engineering, craftsmanship, and design can come together to create an entirely new category.
