In the 1970s, the oil crisis hit hard, shaking the automotive industry to its core. Even BMW, a giant in motorcycle manufacturing, faced uncertainty and considered ending production. But from this turmoil emerged the BMW K100, a machine born out of necessity. It not only saved BMW’s motorcycle division but also made waves in the custom bike scene.

The K100’s origin story was anything but conventional. As the crisis loomed, BMW aimed to create a fuel-efficient yet powerful motorcycle to compete with Japanese rivals. The result? The K100, nicknamed the ‘Flying Brick’ for its unique engine setup.

Early K bike prototypes were daring, with frames hosting Peugeot car engines laid flat for BMW’s shaft drive.

Though radical, this concept paved the way for the four-cylinder K100 and its sibling, the K75 triple, known for efficiency and performance.

Despite its mechanical prowess, the factory K100 wasn’t eye-catching. Custom builders like Saint Joshua in Los Angeles transformed the K100 from mundane to magnificent.

Saint Joshua, with roots in New York and a penchant for precision engineering inspired by his time in Berlin, approached the K100 project with meticulous detail.

Stripping the donor bike down to its bare essentials, Saint Joshua set out to reimagine the K100 with German precision and craftsmanship.

The transformation began with a modular subframe, replacing the cumbersome factory frame with milled pieces that exuded premium quality and simplicity. Electronic boxes were fabricated to house the bike’s intricate wiring, ensuring a clean and sleek rear end devoid of unsightly wires.

Saint Joshua improved handling with a lay-down shock conversion and high-end Showa inverted forks. Braking got a boost too, thanks to Brembo monoblock calipers and wave-patterned rotors.

The K100’s appearance underwent a striking transformation, featuring blacked-out bodywork and burnt copper rims. Luxury details included a diamond-stitched leather seat and matching grips.

Performance elements like the pie-cut exhaust system and four velocity stacks highlighted the bike’s pedigree.

Saint Joshua’s custom K100, named ‘The Konig,’ blends form and function, honouring BMW’s engineering while redefining custom motorcycle design. Originally born from an industry crisis, the K100 has become a beloved classic, cherished by enthusiasts and builders.

In the dynamic world of motorcycling, the K100 embodies resilience, innovation, and the timeless appeal of the open road. As custom trends evolve, one thing is clear: the ‘Flying Brick’ remains an enduring icon of motorcycle craftsmanship and ingenuity.
