Its small size is a definite commuting advantage. Even though lane splitting is illegal where I live (

), it is awfully handy to have a narrow bike with quick responses to rider inputs.
As far as the riding position goes, for me, the biggest problem is definitely the seat to bar distance. I don't think my wrist would have popped the other night if my wrists had been a bit straighter in relation to my torso. Time to stretch the frame... or put the Savage motor/tranny combo in a stretched HD frame or Santee CB750 chopper "plunger" frame. "Amen" made good chopper frames back in the day as well...
The LS650/S40 frame is a miniature FXR/FXD/ FLHP style frame. Square backbone, round tubing everywhere else. Not hard to stretch/re-rake if you are/know a good (airframe or USCG certified) welder. I'm looking at adding about 8 inches to the backbone, with curved and stretched down tube as needed. Add in about 10 degrees of rake, and the FXRS 4" longer than stock front end from work. And a longer gas tank to match, hopefully around 6 gallons. Chief rear wheel/pulley, HD 21 inch front wheel, real rear fender, bags,...
I think working in a bike salvage shop is going to be bad for my bank account...
