What Kalex Engineering does

Kalex Engineering GmbH is a German manufacturer of precision-engineered motorcycle racing chassis, headquartered in Bobingen, Germany, and founded in 2008/2009 by Klaus Hirsekorn and Alexander Baumgärtel. The company designs and CNC-machines aluminum frames, swingarms, triple clamps, linkage components, and carbon fiber parts from solid block material, using Siemens NX CAD together with flow simulation and FEM analysis to individually tune stiffness, strength, and weight characteristics. Its core business is supplying complete chassis and components to professional Moto2 racing teams, a category in which Kalex has won 13 consecutive Constructors' World Championships (2013-2025) and equips 22 of 30 grid riders.

The company monetizes primarily through direct B2B hardware sales to racing teams, with pricing not publicly disclosed and custom orders handled on a quote basis. In 2017, Kalex extended its product surface into Superbike World Championship parts (swingarms with 20% weight reduction vs. stock, adjustable triple clamps) and a Custom line for privateers and custom bike builders, including Öhlins conversion kits and Honda CRF Supermoto/Flattrack upgrades. A direct-to-consumer online shop (shop.kalex-engineering.de) distributes aftermarket racing parts globally, complemented by an active social media presence.

In December 2025, Chinese motorcycle manufacturer CFMOTO acquired a 51% controlling stake through its European subsidiary Helmsmen Europe, with the founders retaining 49% and remaining in management and technical roles. The operating footprint remains lean (1-10 employees, single Bobingen facility), with global race-support logistics provided directly to teams. Kalex also works alongside technology partners including Siemens (CAD/simulation), Composite World (carbon parts), Holzer Group, Millcraft (3D manufacturing), and Motorex (lubricants).
