The R 1250 R is BMW's naked roadster version of the ShiftCam boxer, using the 1254 cc engine with variable intake timing for a broad, muscular torque spread. For 2021 it moved to Euro 5, gained a fresh paint scheme and reshuffled option packages, the old HP sports silencer was replaced by a new sports silencer, and the switchable-ABS option was dropped.
