The F 6 only was made with 1 seat. there are many aftermarket seats that work. Ultimate makes 2 styles, Mustang, Corbin, and some other custom seat makers. Many of us F6 riders have the Madstad windshield. they adjust up and down, but manually. I have not seen an F6 with footwarmers. Perhaps electric socks? And there are a few different styles of luggage racks, and some riders have mounted a Tour Pack, or similar luggage on the luggage rack. Are you riding 2 up, or solo? Just wondering, as my 2 saddle bags and a soft luggage rack bag have allways given me plenty of storage space, as I ride solo. Hope this info helps
