Company History

WSK built straightforward two-strokes that carried workers and students for decades. Designed for rough roads and scarce resources, they emphasized ease of repair and parts commonality. Dealer and cooperative networks made maintenance a community practice. Today, WSKs appear at rallies as living artifacts of a period when motorcycles were infrastructure, not recreation—a testament to durable design and the dignity of honest utility.
