I have a Corbin seat for the Sport for sale. $150
I bought it used a few years back, and it just doesn't fit me.
I am 6foot and wear 38 waist pants. If you are a bit shorter, and smaller in the butt than I, then it might fit you well. The seat is black in front for the rider, and red in the back for the passenger area. The back is built up to look like the cowl. Nice seat, just doesn't fit me. I'll forward a picture to whoever is interested. Unfortunately, it isn't on the Corbin site any longer, so I am assuming its not available anymore.

I'm doing a garage clean up, and will have a few other items available soon.

Cheers,
