Not many options are available on solo for 900's. If you're planing on keeping your stock fender and don't want to deal with any modifications to the fender then the Willie & Max and the Saddle Man are the only two options that I now of. The willie will probably fit you better because the saddleman will move you forward just a bit. Now if you planning to get a full seat then I will highly recommend the Corbin Young Guns. Best seat I ever sat in so far and the passanger side is small enought that it does not mess up the look of the 900. Do keep in mind that all of this three seats are not designed for long touring.
Gitty Up & Go!
