Transmission Reinforcement DS Bike Protection, compatible with R1100 GS - R85GS, made of 4 mm steel. that reinforces the sides in off-road condition.

The DS Bike Protection R1100GS Transmission Reinforcement bracket is made of 4 mm steel and provides critical 
protection for a high stress area. If heavily laden or ridden fast in rough conditions (or all of the above), the rear frame can exert enough leverage to break the transmission case. If you use your GS off-road the way it was meant to be ridden, this is a critical investment to prevent an expensive repair.
