The 2025 BMW R 12 S revives the classic R90S look with modern engineering, but does it still capture the soul that made the original so beloved? Powered by BMW’s 1170cc air-oil-cooled boxer twin, the R 12 S shares its DNA with the R 12 nineT, featuring a new trellis frame, upgraded 45mm forks, revised suspension geometry, and Euro 5-compliant exhaust. In this full review, we test how those changes affect real-world performance, ride comfort, and character on canyon roads and in everyday use. From its heritage-inspired Daytona Orange paint and aluminum tank to its modern ride modes and quirks, this video explores whether the R 12 S is a true evolution of BMW’s heritage lineup or just a beautiful compromise.
