I went for the '15 for the cruise and the potential for resale even though there were awesome deals on the '13/'14 . I think the factory cruise is great and may be a desirable option to future buyers. Is it worth $4K? Time will tell, I suppose. I sure enjoyed it on my Arkansas trip during the extended highway sections!
Regardless, the F6B is an incredible motorcycle. I feel this bike has brought back the simple joy of just riding. On my prior bikes, I was falling into the feeling of needing a destination to go somewhere. Now, I just ride and love every second!!
