I will throw in my two cents here... some may not agree, but to each, their own.
1) Poor brakes. Why do you NEED the best world class brakes? Are you road course racing the bike? Probably not.
My experience and opinion is this: I have an 06 1200 Sportster. While it does not have the best brakes in the world, it is plenty sufficient to stop me in a hurry. Could the "feel" of the brakes be better? Yes. Does that make the bike unridable? Absolutely not.
I am also a classic car guru, and I see this same thing all the time in the hot rodding world. We are conditioned by all the rags (magazines) that we NEED the best of everything... Brembo brakes, Fatman Fabrications front crossmember and suspension, high performance transmission, yada, yada, yada. Well, I call bullshit. Unless you are autocrossing with your car, you don't NEED all that expensive, ultra performance stuff. Sure, it looks nice, and makes for bragging rights, but you can enjoy the same car with stock suspension, used transmission with an inexpensive shift kit, etc..
2) UnHarley sound. This is not true. It is a Harley Davidson, and as such, it IS the sound of a Harley. What it is NOT, is the sound of an air cooled Harley. If you want that sound, you need to buy an air cooled Harley... period.
3) Wiring. As you mentioned, wrap it if it is such a problem. Not a big deal in my opinion.
4) Welding. I haven't seen the reported "poor" welds, but I personally wouldn't let it bother me. I seriously doubt the frames will come apart. If it bothers you that much, get out the die grinder and clean it up, and touch up the paint... or buy a different bike.
I have read all the articles thus far on the Street models, and all items that are purported to be negative, are minor in my book. I don't believe you will find a bike that meets "total perfection", as it is subjective, and we all have differing opinions. If you like the Street, buy it and enjoy it for what it is.
