BS Quality is a motorcycle-cylinder specialist based in Cuarte de Huerva, Zaragoza, Spain. Founded in 2018 by Enrique Marzal, the company draws on more than 40 years of experience repairing and reconditioning two- and four-stroke engines. Its core service is cylinder Nikasil plating, which applies a nickel-silicon coating to restore worn or damaged cylinders while preserving their original diameter. BS Quality uses its own nickel-silicon formula and completes the process in-house, serving individual riders, motorcycle workshops, piston importers, and competition teams across Spain.

Customers can choose from three service packs. The essential pack includes cylinder plating and return shipping; other options bundle pistons, and the complete pack also includes top-end or engine gaskets, with discounts on selected items. The company works with leading piston brands including Vertex, Wössner, Prox, and Athena. Its return-shipping offer covers mainland Spain and the Balearic Islands. Work comes with a 30-day defect warranty, subject to stated conditions, and customers can request a quote by WhatsApp.
