The upright seating position on my stock '07 VStar 1300 is killing my back and my butt. Long rides have become unbearable! So...I'm trying to modify my overall riding position to allow comfortable long-distance riding. First thing I've done is purchase a Mustang seat with backrest. Now I need advice on a set of handlebars that will allow me to sit further back. (I also intend to put highway pegs on my factory engine / crash bars. Any good advice on handlebars would be welcome...preferably they will not require all new control cables.
