Oops, wrong topic..
It's purely a personal thing.. I didn't have the choice when I bought my 02' KLR since it was used, but a couple years ago I bought a new GoldWing and passed on the Extended Warranty..
Much like the KLR, I don't remember reading to much about how either of these bikes are typically falling apart and breaking down..
It's a decision that really only you can make.. Were it me buying a new KLR, just as I did on my Wing, I'd pass. Although, the Wing came with a 3 year warranty, so that had some bearing into the issue... 2 years into it, the closest the bike's seen to a dealer is on the road as I've ridden past.
I look at it this way.. You have 1 year of warranty that comes with the bike. If there's an issue that's warranty related, it's going to show up in the first 1000 miles. After that, you're going to have to fight with them to cover anything anyway..
