Diamond Atelier unveils 205bhp DA#22, calling it the world's first hyperbike

The term "hyperbike" gets thrown around fairly regularly whenever a manufacturer bolts a turbocharger to something expensive and fast. Still, Munich custom house Diamond Atelier reckons it's gone one step further with the DA#22, a machine it describes as the world's first genuine hyperbike.

Unveiled publicly for the first time at the 2026 Goodwood Festival of Speed, the DA#22 started life not with an engine or a chassis, but with a design brief. Internally known as Project ULTRON, the bike was conceived as a completely new silhouette first, with the engineering packaged around the styling rather than the other way around.

Underneath the hand-formed aluminium skin sits familiar Austrian muscle in the form of KTM's LC8 V-twin lifted from the 1290 Super Duke. Diamond Atelier says output stands at more than 205bhp, placing it at the tail end of modern superbike territory – albeit with considerably more visual drama than your average litre production bike.

The bodywork is arguably the star of the show. Created by Marvin Diehl of KRT Framework, every aluminium panel was shaped by hand over a process that reportedly consumed more than 800 hours. The resulting design features dramatically shortened proportions, hidden electronics, a cockpit concealed beneath a recessed glass panel and a floating tail section that appears to hover above the rear wheel.

Supporting the package is a Wilbers TYPE 46 RR front fork derived from World Superbike competition and a bespoke rear shock built specifically for the project. Diamond Atelier says component selection wasn't solely about outright performance, but also ensuring the bike remained serviceable despite the tightly packaged design.

Then there are the details that push the DA#22 firmly into hypercar territory. Titanium components including the exhaust system and top yoke have been 3D printed by Aconity3D, while DKB Special Parts supplied Formula 1-inspired switchgear and an illuminated clutch cover complete with a glass inspection window. Gilles Tooling provided the controls and rearsets.

And yes, there really is a diamond fitted to the bike. Set in sterling silver and mounted in the centre of the upper triple clamp, the stone serves as a literal interpretation of the company's name.

If that wasn't enough, the DA#22's paintwork doesn't simply reflect light, it creates it. Developed specifically for the project by Alex Bloch at Stilbruch Lack, the finish glows red when an electrical charge is applied. Diamond Atelier says just one litre of the paint was ever produced and every last drop went onto this motorcycle, meaning the prototype can never be recreated exactly as it appears today.

For now, the DA#22 remains a road-legal prototype and a rolling statement of intent rather than a production motorcycle. Diamond Atelier says it represents the beginning of an ultra-limited series aimed at occupying the gap between superbikes and the hypercars that usually dominate the Goodwood hillclimb paddock.
