The oil cooler of the R1150 GS and Adventure is positioned in the best place for optimal air flow, although a consequence of this is that dirt converges on it from all angles. Stone chips, dead flies and other detritus accumulate in its fine ribbing. Cleaning it is very difficult and requires a lot of manual work.
The fine-mesh stainless steel cooler protection grill provides effective protection for the cooler and ensures optimal long-term cooling air flow. It's also an optical highlight. The protector is made of a durable stainless steel mesh sandwiched between a black and a silver anodized laser cut frame. This is so that the protector can be fitted with either the silver or black color of the grill frame is seen from the front (whatever looks nicer depending on the color of the bike).
