Kijima vs Zeed, each has its pros and cons.
While I don't like that the tail cowl has to be removed on the Kijima, at the end of the day, being bolted from above and below give me more confidence with the Kijima rack for carrying heavy items.
Here are a few bullet points comparing each one:
Kijima (Webike Japan):
+ bolted onto the bike above and below the tail section
+ larger platform for more freedom to place a top case base plate
+ has those little mushroom pegs welded to the bottom, as extra bungee attachment points
- can make the seat hard to install and/or remove (push down hard to install, and also push down on it to relieve pressure on the latch when using the seat release, or you may bend the key!)
Zeed (Zeed Parts Thailand):
+ thick tubing for larger weld surface
+ does not affect the seat installation, no plastic to remove
+ also has mushroom pegs on underside for bungee attachment
+ nice price!
- only mounts to bottom, so make sure the bolts are torqued up tight! Will show a bit of flex with heavy loads.
- small platform combined with thick tubes limit the range of positions for installing a top case base plate
While I am fairly happy with both of them - if I had the money to start over, I would probably choose the Hurricane rack from Webike which looks much sturdier than either of these racks, but I cannot comment on that from personal experience.
