By the way, there's another post that shows one with what looks to be a Shad topcase.
Yep, that one is mine. Here is the post with images:
http://www.kymcoforum.com/index.php?topic=26194.msg186640#msg186640The underseat storage is really big, but would not fit a full face helmet, so we got the rear case. A 3/4 helmet would likely fit under the seat, but I value my chin.
The rack the dealer ordered from Kymco, and the shad case is just that. Dealer installed both, so I can't comment on how hard they were to get on there. Very happy with the case and rack. With the Shad you can turn the key the other direction and the top case comes off completely, leaving just the rack...super nice.
You made the right choice switching to the 150i from the 200i. We have 72 miles on our 150i and it is awesome. Very fast for a 150 and great features. Rides awesome. No issues to report so far, just wish we would get a dedicated forum here for the bike.
