Company History
Leonhardt Manufacturing sits at the outer edge of motorcycle excess and engineering theater. The Gunbus 410, powered by an aviation-scale V-twin, is less a commuter than a statement about proportion, machining, and the boundaries of what a ‘motorcycle’ can be. Built in tiny numbers with painstaking craftsmanship, Leonhardt’s work emphasizes billet artistry, weld quality, and structural integrity, so that even improbable dimensions behave with dignity at speed. Beyond the headline machine, the shop has produced bespoke components and specials that showcase German metalwork at couture scale: precision fasteners, immaculate surface finishes, and kinematics designed first-principles rather than copied. Homologation is complex and volumes microscopic; owners commission rather than buy, participating in a process closer to coachbuilding than retail. Historically, Leonhardt proves that awe and engineering rigor can cohabitate. The Gunbus is a rolling sculpture that still steers and stops, a reminder that one-off builders expand the idea space the mainstream later mines—materials, processes, and the courage to treat a motorcycle as an ambitious, almost architectural object.
