With the right parts anything can be done.....
I swapped my 21" for a 19" on my Wide Glide when I went to Metzeler 880's, made a huge difference in my handling. Don't think I would ever go back to a 21". Just my $0.02
I don't think there is a stock HD wheel that bolts right up to your bike, so most of the folks on here are lacing their stock hub to a 21" with good results.
I have a 21" front wheel on my superglide. I bought the bike used and the previous owner put it on. I definitely like the looks of it, and since I have not driven the bike with the stock wheel, I cannot speak to which is better for handling - 18 or 21.
