Exposed electrical as on ‘18 softails
Once you're finished and everything is dry use a product like Gunk engine protector that doesn't contain silicone and spray everything down and let it dry. It will may the next cleaning 10 times easier.
I've done it dozens of times without ever having an issue. If you think your electrical can't handel water then you've never ridden in the rain. Try putting down 400 miles in downpour 14 hours of riding and see if your electrical is somehow dry and protected by your seat, trust me it ain't.
Touring bikes have a snap on plastic cover over the ecm data port and other electrical components, everything is exposed and it gets wet everytime you wash your bike.
Trust me, I'm a fanatic when it comes to cleaning my bikes, the bags come off and I clean in areas people never think of.
If Harley is indeed "serious about aiming for new customers", some instructor out there had better tell them how to shoot...
Bottom line is these bikes are built to be properly waterproof.
However - once i took the seat off my 2018 Softail Fat Bob, I WAS very surprised about the amount of dirt under there. Definitely could be improved upon with some form of mid frame water/spray deflector.
I use ACF50 liberally on my bikes, so not particularly worried, but I do agree it's not good design - and I will either make or buy something to mitigate it.....
