The 2026 Z650 S is the sports-styled version of the 649 cc twin, now with electronic fuel injection (EFI) and a trellis frame. The page lists three EU colour schemes: Ebony with Carbon Gray, Candy Lime Green with Carbon Gray, and Graphenesteel Gray with Flat Spark Black. The figures are close to the Z650RS table apart from the injection and chassis details.
