depends on how much $$ ya wanna drop. do you want throw overs or do you wanted mounted bags? You can get cheapo throw over bags for 50 or sixty bucks or you can spend upwards of a grand on bags....depends on what ya want.
Osprey saddle bags are fabulous...you CAN spent more but WHY. I have the quick detach mounts and my FXSTC goes from a crusier to a touring bike in 30 seconds. GREAT BAGS!!
