Ive got the standard roadster seat, the triumph dual pad gel seat, the classic touring seat the boys are talking about and a corbin solo.
I think the triumph dual pad gel looks the best but is by far the worst. after 20 mins you can't wait to get off. the standard is just ****. the corbin initially feels to firm but after 8 hours you still feel fresh, the dual touring from the classic, brilliantly comfortable as soon as you hop on and my arse thinks it is fine for a couple hours before i hop off for a stretch and keep going. Have done 800k's in one day on this seat and was never too uncomfortable but I did find my arse going numb after about 200 k's. nothing a quick break didn't fix. about a 1/4 the price of corbin and does a much better job of helping the suspension soak up the road imperfections.
