I had a turkey vulture flying across the highway at low altitude strike my bike just left of center, causing the left radiator to spew its fluid. The bird also cracked the front fender and took out some body panels on the left side. I had installed the BMW radiator guards, but these guards did nothing to prevent any damage since the bird was quite heavy, estimated at 10 lbs. The damage is initially estimated at $1500 in parts alone. I realize this is an unusual situation, but I'm thinking of mounting some sort of protection to prevent large objects from entering the radiator area, possibly attached to crash bars. I don't have the crash bars yet, but I have ordered the Altrider lower crash bar set, which are in development but expected to ship by the end of June. I was going to add the Altrider upper crash bars later once these are developed. Checking to see if anyone has a solution for this.
