I ride a lot, and sometimes for long distances. Any recommendations for an aftermarket seat?
I know there's Corbin and Saddlemen, but if there's any other options I'd be grateful to hear them.

 

I had a Sargent seat for my F3 and thought it was a well made product - but I didn't like the way the bike felt with me two more inches in the air and the higher front position was doing unpleasant things to my male anatomy.

Shop carefully here.

I bought a new seat cover from them to replace the seat and think it's the single nicest mod on the bike.

 

I've got the Corbin and love it. Works great on long rides (over 500 miles). You could also find a good upholstery shop and they could redo the foam in the stock one and recover it. Worth talking to someone about and compare pricing.
