So state plating issues aside... I also have a 2011 FE390. I took a look at the parts for the Euro version of the bike, and found the part numbers for the missing stuff. I THINK this is a complete list. Any comments?
Sicass wants $320 for their kit. Seems a little steep.

total is about $290, but I'm sure ktm-parts will post a discount code for the 4th. Some of those parts aren't needed, and you might be able to find a cheaper turn signal switch.
