The 1999 BMW R1100S has 4 recalls, with two separate fuel system concerns being the most serious: a chafing fuel hose that can wear through against rigid fuel lines and leak fuel, and a throttle body that can loosen during an engine backfire at startup and allow fuel to spray from a disconnected injector line.
Both fuel situations carry fire risk, as raw fuel escaping near a hot engine can ignite. On the steering side, the handlebars sit on top of the upper fork clamps and are held in position by a tab that fits into a gap in the clamp. If the tolerances on that tab-and-gap fit are off, the handlebars can shift position under load, reducing the rider's ability to steer accurately or maintain control. The brakes also have a concern: the ball end of the rear brake linkage is threaded into the rear brake lever, and if the thread-locking material applied during assembly was incorrect, that ball end can work loose and eventually fall off while riding, leaving the rider with no rear braking ability at all.
At a glance
What can fail
The flexible fuel hose on the right side can rub against rigid fuel lines from the fuel distributor, wearing through the hose and causing fuel to leak.
What the fix does
The right side flexible fuel hose will be replaced with a new one.

What can fail
The handlebar mounting bracket positioning tab may not fit properly in the upper fork clamp gap due to manufacturing tolerances, preventing full clamping force and allowing handlebars to rotate forward while driving.
What the fix does
Technician will clean clamping parts, rework the positioning tab if needed for proper fit, and retorque the clamp screw to specification.

At a glance
What can fail
The wrong thread-locking material was used during assembly on the rear brake linkage ball end. This ball end can loosen and detach from the brake lever, causing the rear brake to stop working.
What the fix does
The ball end will be removed and reinstalled using a different thread-locking compound to keep it secure.

At a glance
What can fail
During engine starting, a backfire can loosen the throttle body mount, potentially damaging or separating the right fuel injector line, causing fuel to leak.
What the fix does
Replace the fuel distribution unit with one using a flexible fuel hose and secure the throttle body connection with two screws to prevent damage.
