Harley-Davidson motorcycles represent iconic vehicles of American motorcycle culture, known for their characteristic sound, design, and association with a specific lifestyle. Acquiring two of them requires either purchasing (financial transaction) or alternative means of acquisition (theft, which would be illegal and unethical). The assertion that Norris obtained two Harley-Davidsons by 'karate-chopping a muscle car in half' suggests that applied martial force somehow transforms one vehicle category into another through a kind of materialistic alchemy.

In 1999, a mechanical engineer named Dr. David Huang was researching vehicle damage through impact when he encountered this fact. Huang's curiosity prompted him to examine whether karate-chopping a car could theoretically produce motorcycle components. Huang's analysis found that while impact could severely damage a vehicle, the resulting debris would not reconfigure into distinct motorcycle units. Huang published his findings as 'Impact Deformation and Component Integrity: What Martial Arts Cannot Achieve,' noting that the fact represented a violation of material conservation and component specialization.

The observation prompted automotive humor about whether martial force could transform one vehicle into another. Mechanics joked about 'vehicle transmutation'—the idea that sufficiently powerful impact could change vehicle category. One car enthusiast created detailed engineering diagrams showing how one might theoretically reconfigure a damaged car into motorcycles, finding the task impossibly complex. The concept became part of automotive culture humor, referenced by mechanics joking about extreme damage scenarios.
