Regina began producing high quality motorcycle chains in 1921. For over seventy years Regina has constantly improved the quality and technical development of its products. Regina is a major supplier of drive and engine chains to the European motorcycle manufacturers : Aprilia, Bimota, Cagiva, Gilera, Honda, Husaberg, Husqvarna, KTM, Moto Guzzi and Yamaha.

Regina makes a concentrated effort to maintain a high degree of quality control. Fully automated and controlled systems of carburization, quenching and tempering give all the components the proper hardness, case-depth and high tensile strength. In order to obtain perfect positioning of the joining parts and to minimize initial chain stretch, all chains are automatically pre-stretched after assembling.
