has anyone put a 21" on if so how does it handle????

 

There's tons of threads on the 21" wheel, many love it but others have gone a more conservative route - I went 18/18 on my Road King.

 

Nobody has ever done that before. Try using the Search Function in multiple sub-forums to get your answer.

 

With the 18's & the lwr profile tire, is the overall dia about the same as the stk 16"?

 

Yes, exactly the same diameter up front, and the rear 180/55/18 is a little taller than the 180/65/16. The math works out to approx .6" taller (diameter), so that only adds .3" to the ride height and I don't even notice it.

The new Road King Special comes with the same 180/55/18 out back and a 130/60/19 up front, so I was comfortable in my decision to go 18/18 based on the fact that the MoCo uses similar sizes. I just wanted a little more sidewall up front as I live in San Francisco and the city roads suck. Fortunately, we have amazing coastal roads that aren't too far from the City.

 

Yes I have one and yes it does handle slower but these things have so little lean angle it doesn't really matter. My boards still throw sparks at stock ride height.

 

Front or rear?

 

I think it made handling easier. It does raise the front end, so I did install the Progressive monotubes lowering kit.
