Just bought a 2011 FLHXSE2 on eBay with only 1900 miles and it arrived a couple weeks ago. This is my 7th HD and so far my favorite! I have had:
2000 FLSTS
2006 Road Glide
2007 FLHTC Electa-Glide Classic
2008 FLHX Street Glide
2010 FLHTCU Ultra
2012 FLHTK Ultra-Limited
I've had some nice bikes, but this one is just plain fun to ride! I've riden from SD to Sturgis RT twice and can't wait to do it again on this bike. I finally came to the conclusion that after adding all the stuff I do, it might be better in the long run (especially given the resell value) to just buy a CVO, although that isn't keeping me from finding things to add to it as we... I've already added the highway pegs, 4 point dock, Stealth luggage rack, matching rider backrest and K&N air filter. It came with the V&H True Duals/Dual slash mufflers w/quiet inserts (still pretty loud...). The previous owner didn't have a Fuel Management system installed, so I popped a V&H Fuel Pak on for now and it seems to be running great (although it does occasionally pop).
Would certainly like to hear about other recommeded tried-and-true mods, but I am lovin' my new bike!
