I forget the year (2009 or 2010), but recently Harley redesigned it's touring bike frames (FLH series?) to both increase the strength and to bring the rear wheel into alignment with the front. Previous models had an offset of the rear wheel from center. We found out about this on an MCN touring bike comparo in Death Valley we did years ago when Lee Parks was still editor, the Harley would get down right scary anywhere near 75-80 MPH. Looking into it further Lee and Dave discovered the offset and that it was deliberate. I think Harley did that to accommodate the belt without making, what should have been, the needed changes to the decades old frame design at the time, originally designed for chain drive.
I remember the recent new redesigned frames Harley was bragging about a year or two ago and thinking it's about time.
The bike we were testing was bone stock.
