The sportster has more of a traditional foot position. My recommendation is to relocate the pegs closer to the seat, and risers to bring the bars back.
I don't think it's ever a good idea to not be COMPLETELY comfortable on the bike. The style of the bike is great, but if it doesn't fit well, and you can't change you really need to reconsider what you're going to ride.
The peg kit ain't cheap. The other option is to buy a Bonneville Black!
