Nightster/883 Iron seat

[wmg1299]

I'm a tall guy, but I really like the look of the Nightster and 883 Iron. Unfortunately, I just don't fit comfortably on the bikes, even with forward controls installed. I have a tallboy seat on my Softail, but H-D apparently refuses to make one for the Sportster models. Does anyone know of any custom seats that work to move the rider up and back, just like the tallboy does for literally every other H-D model?
