The company was founded in 1919, initially manufacturing chains and free wheels for bicycles. The production of motorcycle chains began in 1939, bringing early success and victory after victory ever since. Over a period of more than 90 years, many trophies in every discipline and category, both road and off-road, were won, resulting in more than 325 world championship titles. But the biggest success is using the races as a testing ground for ultimate product and technology development, resulting in exclusive patents: Z-ring, Chromized pin, shaped bushing, and many more. Applying these technologies to series production makes the real difference between Regina and all others. Each Regina chain, type by type, category by category, provides the ideal performance for all types of motorcycle or ATV riding. A complete range of increasingly advanced and innovative chains, as part of an enduring quest for two fundamental requirements: maximum functionality and complete safety. Rivet type 19 links resists mechanical stresses in the same way as other links of chain. Special tools are required to required to correctly install this link.
