First I want to thank Logan and Billy500 for their information. I will be looking over those recommendations.
I also discovered that there was another thread, "Top case only pics, no side bags?" that covered the top box question in detail. From reading that thread. it seems that I need to get a Euro Tail piece PN: 99994-0341-40R from Kawasaki that allows me to attach a top box mounting rack to the bike. Are there other sources for this part other then Kawasaki?
Is there someone that could provide pictures of the Euro Tail piece, both front and back, to help me understand how that part mounts to the bike? If possible, include a picture of all needed hardware. I believe I need to get both a rack and the Euro Tail piece to get a top box to mount on the bike.
Thanks!
