that seat would have been 402 shipped from me and it would have been packaged properly, suzuki uses fairly cheap packaging on the seat and the way it's shaped requires extra padding and reinforcement in certain areas or they will always show up damaged.
good luck with your insurance claim. hopefully UPS doesn't ask to inspect the package because there is a crush rating they will look for and the suzuki stock packaging doesn't have that rating. so the claim may be denied. We had to learn the hard way.
