Thats actually the stock seat. The passenger half of the seat comes off with two bolts. As far as a solo seat goes, I don't like it. It's way too big for my tastes, and when I get on the gas, it feels like I'm gonna slide right off the back of the bike. I'm going to get a Corbin Hollywood Solo I think.
Axle covers are on the list of things to do (long list).
I bought it used with 1000 miles on it, in fact it had just come out of the shop for the 1k mile service. The previous owner did the bars, chrome switch housings, braided cables, mirrors, and the stage one. I just got rid of the floorboards and the stock rear tailights.
