Whatever model isn't a Harley... Sorry to say that if you're a speed freak, you're going to be wildly disappointed with HD. Your best stock Harley would be Screamin' Eagle 110a. Even with that, you'll get out ran by anybody with a 1200-1700CC bike from any other brand on the market (that isn't a scooter... Well, maybe some scooters too). There might be an odd bike in there that will fall behind, but not many.
In the whole grand scheme of things, if you're looking for speed in a bike and want it to say Harley on the tank, you're going to want a V-Rod or have DEEP pockets. Like buying an aftermarket built motor deep.
The Harley 103" engine that you find in the modern BT models is a nice engine, but it's built for cruising. It doesn't make a lot of power or even torque in stock form, as it's been really choked by the EPA. Throw in some cams, intake, exhaust, welded crank, better bearings, and a nice tuner and you'll have a really fun engine that will last you quite a while. You're still not gonna win many drag races unless you are racing other harleys. It's just not what the bike was built for. At all...
