Well, here is my 2 cents.
I bought the extended warranty (not the Honda warranty) on my 2005 and had the engine removed twice. (yes 2 times). Plus they replaced the steering bearings with All Balls tapered bearings when I complained about them. For the $600 I paid for it, it saved me thousands of dollars. Being said, I also bought the extended warranty on my 2018 Tour DCT. Why? Because all of the electronics on that bike were new and no one knew what would happen to them in a few years down the road.
The Honda extended warranty, "we are told" covers everything the factory warranty covers. That isn't what it says in the warranty!
One thing that Honda does not cover is gaskets and seals. They call them "Expendable Maintenance Items". They can cover them if a repair of the engine is made, but if a gasket or seal is leaking by itself, they may not cover it. You should check with your dealer and read what the warranty covers, it is all in black and white.
I also found that the Honda extended warranty says it does not cover audio and Navigation equipment, people are quick to argue the point.
All I can say is that is what is written in black and white, and that means I could be stuck paying for that myself if Honda was not willing to cover it. Do I want to take that chance?
I do know someone with a Goldwing that has had their navigation screen replaced under the extended warranty, I believe twice. The 2017's have had some failures of those screens. I don't know if they bought the Honda one or not.
I went with
Aegis Warranty that is what my Honda dealer sells and they cover these things in their warranty.
Warranty is only insurance. If you feel like you don't need it then you shouldn't get it. Some think it is a waste of money. $700.00 is not a bad price for a Honda warranty. One trip to the shop for a problem could cost you that easily these days. Good Luck.
