My friend purchased a RK (probably not a good comparison because they are a much larger HD than the rest) and my SM hangs with him all the way up to around 80ish. Man, you should have seen the look on his face, but being a motorcycle mechanic he knows that there is a lot less mass to the Triumph than his RK.
Don't even ask about hitting the twisties. Lets just say I have enough time at the bottom of the mountain to enjoy a cup of coffee by the time he reaches the bottom (A little hyberbole but funny nonetheless).
