So I did a yahoo image search for the bandit 400 a couple weeks ago and found a picture of rearsets. When I went to the website it was a Japanese company called Coerce Racing Project, a part of Dax Corporation. I found an importer that got them to my door with tax/shipping for $364 (they're in Encino, CA). They arrived today and look pretty darn cool.
Brackets are CNC aluminum, levers are aluminum too. Pegs are folding, knurled and slash cut. The only bad part is that the instructions are in Japanese, but they have diagrams, so I think I can figure it all out. I'm hoping I can find time on the weekend to do the install. My B4 is down right now anyway while I wait for my regulator/rectifier to come in. For anyone who thinks $364 is a little pricey for rearsets on the B4, I'm going to be putting my Raask rearsets on eBay if the assembly of these goes well. I know Wild Hair has the Gimbel rearsets, but I don't like the location of the master cylinder on theirs and the starting price is $360 (not including shipping) and the pegs look fixed.
