I got in on the financing this spring as well. Household doesnt require that you keep full insurance on the bike, but they do have a lien on it (meaning they keep the title til its paid off). This was the way it was explained to me at the dealer and I found it odd but didnt care to argue. On contacting my insurance company (state farm) they said Household does require collision coverage on the bike. Once again, I didnt care to argue since i wanted coverage anyway (since i got the gap insurance). This works out to $500/yr + $300 for 5 yrs of gap (or however long the bike is financed) so i feel pretty well covered. It would suck to have a $8000 loan for a pile of scrap parts sitting in my garage.
One other thing I thought i'd mention in case anyone hadn't figured it out: The minimum payments on a typical bike with the kawi financing is a BAD idea. I financed $8700 to get my ZZR plus maintenance, gear, and gap ins. This means that I would be paying around $40 a month in interest and $9 toward the principle. At the end of the 24 months, the refinance would be killer! They would probably stick you with over $200/mo in payments, since the balance will still be pretty high. I have been paying the bike off as fast as I can to try to get it done inside the two years. Unless you have a reasonable principle (under 5k) I would strongly reccomend you do the same.
