Corbin, LePera, Mustang and Sargent should have some alternatives. Diamond Custom Seats and Hartco Seats Int'l will make a seat for you based on your height, weight and inseam. And of course StarBike's sponsoring vendor, Ultimate Seats, is worth looking into.
I just bought a Corbin saddle for my 2004 Kawasaki ZR-7S.
It came with no problems, looks great, feels great...but the one thing you might want to think about...(the very thing that makes it feel great, look great, etc...) is that the actual saddle covering (any parts that your body contacts with, on the Corbin) is a very high quality natural leather
, and so, you need to not only saddle soap it occasionally, but, more importantly, if the rain starts falling, or you are going to wash the bike, you need to also buy a vinyl saddle cover (I would suggest that you do...some don't bother...) to rain/wash proof it. Sometimes, one forgets that most OEM saddles, are fully waterproof over its entire build.
