I have the Utopia on my OEM seat. Couldn't be more pleased. Just road from NC to Fl. 645 mi. Very comfortable all the way. Actually cushions the "whip" you can get from some road bumps. One of the things that helped me was to use a longer serrated knife to cut through the foam. take your time and the install will go smoothly. Great seat back! Ncf6b

It's very easy to do use a serrated knife blade to cut the foam it will pull it out as you cut it.
Ok he's done
I chose the f6b over a wing for the reason to be able to throw a leg over it easily.
Will installing utopia backrest hinder that in any way?

I like the other version you can buy because its not as tall. I installed a Utopia and thought it too tall, so I morphed a Harley pad onto it using the Utopia hardware. The utopia is just too tall for me. They really ought to offer different pad sizes. I forget the brand of the other backrest.
