The oil cooler is kind of exposed, especially if you have cheap crash guards (or none). I had to replace mine after a mild crash because it was broken at the seams. That thing is expensive and it takes a while to get a replacement, not many dealerships stock that part.
This nice Royal Enfield OEM protective shield made from brushed aluminum takes care of that. It shields only from the front though …
