When a person thinks of accessories for there new bike they think of exhaust, handle bars, mirrors, and more chrome. When you get older and all the cool accessories are on the bike ya look at that next 4,000 mile trip and think of the booty, or the wife thinks of her booty, thats when a very important accessory comes into play. The best seat I have every put the ole booty on for those 4,000 mile trip has been made by Saddlemen. Now like I always say everyone has there own favorite. But I have settled on the "gel inserted seat". Saddlemen has proved to me to be the best most comfortable seat. And no I don't have any affiliation with selling Saddlemen. I work in a hard rock mine. But now back to your question, I have looked up some Saddlemen seats and the two solo seats I would reccomend would be the "Take Charge" and the "Renegade 2 Solo Seat". These two seats have a deep lumbar support I think you are looking for. You can see these at
