I’ve ridden in the rain far too many times for my liking, never had any problem with TBA. Only problems:
MC jacket, I did a good job waterproofing, now the rain just runs down to my pants, think it is time to buy some rain gear. At 60 mph in down poor rain really stings hands, I have full face helmet, no problem with face. The biggest problem finding a place to hide out till rain subsides. Oh yea cleaning TBA after riding in rain, lots of crap everywhere. I use lots of Q tips, and Windex or invisible glass.
