BMW issued a recall on the R1100S model

On certain vehicles, the left and right high-mounted handlebars are positioned on top of the upper fork clamp and are clamped to the top of each upper fork tube. Unfavorable tolerances may exist between a positioning tab on the handlebar mounting bracket and the gap in the upper fork clamp into which the tab fits. As a result, the specified torque value of the upper fork clamp screw and, therefore, maximum clamping force on the upper fork tube may not have been achieved. This could cause the handlebars to rotate forward under certain driving conditions, possibly resulting in a vehicle crash. Correction: Clamping connection parts will be degreased, positioning tab will be reworked if necessary to fit properly in the gap in the upper fork clamp and the clamping connection torque will be reset.
