The only thing that has gone wrong so far is stripping of the switchbox bolts during a hand-grips upgrade. The original bolts were as soft as butter. I bought strong replacement bolts for 88 cents.
I have had this bike for about a month, and I have been on it non-stop since then.
Everything about the bike is amazing. It rides nice, handles well, is comfortable, and surprisingly, has a lot of power. Though it's an 800cc, it's fuel injected, so it gives a tad more of a top speed and acceleration. It has no problem keeping up with my buddy's Harley Road King, which I believe is a 1400+cc.
The bike is a great deal, beautiful, and VERY easy to upgrade with add-ons. It's loud, but not too loud with stock pipes.
I listen to Hulk Hogans 1984 theme song on my ipod on repeat when I ride around on this bike, so it's not extremely overly loud. You can even use the exhaust to heat up a homemade bologna and cheese sandwich.
Listening on repeat is the most amazing review point I have read thus far :)
