IMO it is worth it. My engine seized at 7hrs due to a broken oil pump. If it had not been for the factory 6mo warranty, I would have been completely SOL. I went ahead and purchased the ext. warranty after that ordeal, worried my bike was a lemon. Jury is still out.
If you plan to mod the heck out of it, and your dealer service guy is not your best friend, however, you will likely be told that you voided it. If you will keep it mostly stock, get the warranty.
The Honda customer reps will tell you themselves when you come crying, "we never guaranteed our ATVs to be perfect, sir." Therefore, cover your butt as much as you can.
