In 2013, when I purchased the bike, I immediately called Mark . They made the best seat I've ever ridden when I had my 2005 Gold Wing, but didn't make a seat for the F6B (since it was so new). Mark said to check back with him, which I did in November, 2015.

I guess I nagged him enough, because he agreed to make the very first Hartco seat for me if I would send him a seat pan from a stock seat. I bought a used stock seat and sent it to him in late-Nov/early Dec.

Today, I am happy to say I have the first Hartco Seat made for a F6B!

I haven't ridden on it long enough to give you a long-term report.
