I have less than a year remaining on my extended warranty. May of this year my rear end was leaking. Not bad. But with the rear end having know issues on all years of 1800s Wings I felt it a wise investment. Especially when I’m on the road and not near all my tools. As for the rear end I knew that Honda would most likely replace seal/ o-rings and that is what they did. What scares me the most would be if an electrical gremlin reared it’s head. As some one else mentioned, I had the clutch safety switch go bad. It was more cost effective for me to buy the $14.00 part and replace it myself.
