I installed my Sargent seat on Saturday, April 23. I've since put about 1,500 miles on it, including a 700 mile, three day trip to Galveston and back. A few weeks ago I did a preliminary review of the Sargent where I went over fit, inseam length, flat-footing at stops, etc... Here's that review: http://www.advrider.com/forums/showthread.php?t=134119&highlight=sargent But I said I'd do a long distance review after after a May 10-12 ride to Galveston and back. From my home in McKinney, Galveston is 325 miles straight down I45 through Houston. Nothin' fancy, just a straight interstate shot. In short, the Sargent is way better than stock for a long ride. After an hour on the stocker my butt is hurting at two pressure points, and after two hours the pain is darn near torture. And a ten minute fuel break doesn't help much as my butt would be sore minutes after getting back in the saddle. My 300 mile day experiences with the stock seat were awfully painful to the point that the last 50 miles or so were nearly dangerous since I was constantly standing and shifting my weight. With the Sargent two hours is a breeze. After two hours there is a bit of a squirm factor, but nothing that a one second stand on the pegs doesn't cure for another 15 minutes. But don't confuse "squirm" with "hurt." At no time did I get monkey butt pain. And the three hundred mile ride was no big deal. We filled up twice (my buddy's range was only 150 miles) and the butt was fresh for another couple hours after the ten minute gas & stretch break. I have no doubt that the Sargent would be just fine for a 500 mile day.
