Try one of those imitation shearling covered gel pads from JC Whitney. The gel part slides into the faux shearling seat cover through a zipper in the back of the cover. They're cheap and they work ok. They're held in place with two inch-wide-or-so u-shaped clasps that fit underneath your seat edge and are snugged up to hold the pad in place. A large one is about $80. I've used one on my ST1100 and ridden a couple of 800 mile days with it. Not great but better than the stock seat and not a ton of money either.
Dear Suzuki your new cruiser naming system sucks. None of us know which bike is which and this in on an Internet site dedicated to motorcycles. A letter plus a number just doesn't work unless your BMW.
I've used a ProPad (www.thepropad.com) on 2 different bikes. It's a gel pad. It doubles the time I can spend on a bike before I get butt-ugly. On my cruiser that meant 2-3 hours instead of an hour. On my SV1000, it means a day and a half instead of 5-6 hours.
I just recently purchased a 06 M50 (gray if you must know). Of the 3 people who've been on it, I'm the only one who hasn't had a problem with the seat. Possibly due to my inexperience, causing me to worry about other things.
This is odd, due to the fact that I can't stay seated in a car, errr cage for very long without having great discomfort in my tail bone and lower back.
I may still get a gel seat, but only time will tell.
