I was thinking about this yesterday when I went on a day long almost 800 mile ride, "There And Back Again". Rode to New Orleans, had cafe au lait and beignets (In pre-Mardi Gras traffic which was terrible in the French Quarter) and back home. Here's my story.
When I bought the '14 RT, plain vanilla version*, I took off the next day on a 600 mile ride. When I got back, I could not walk. Literally. I had to have help getting around. The next morning I was at my Family Doc who gave me a cortisone shot and by afternoon, I was walking OK. But, BEFORE that shot, I had ordered an Ultimate seat. Rush delivery. Prepped the bike by removing the factory seat and in less than a half hour after UPS showed up, the Ultimate was installed (the one with gas door which is so fantastic I can't..never mind) since that day, I've ridden 14,000 miles. NEVER ONCE have I ever had a single instance of a dead spot or sore butt or been unable to walk. You know, sometimes when you get off the bike after a long segment and you want to rub your butt to restore circulation. NO NEED TO DO SO with the Ultimate seat. The comfort is MOST EXCELLENT. I've been riding motrocycles of many brands. For over 40 years. This Ultimate is the most FANTASTIC seat I've ever used. I once rode a '67 Triumph Bonneville (about a half-inch of compressed foam) from Naples Italy to Amsterdam and back and suffered greatly but that's all there was so... (Navy) I've ridden West to East Coast on a Yamaha XS1100 and a BMW K1200LT and while they're great bikes, the seat was never ever as great as the Ultimate. But then, this is just me. Others have their story to tell.
*I've added things to the suspension, tires, handling, etc that made it an almost totally different handling bike from the one I rode out of the dealership. About 4 large worth.
