Yah don't go for the Speedmaster seat. Your wife will hate you. As has already been suggested, get the Corbin. It is pricey but from what I hear well worth it. I ordered mine a few days ago.
09 Speedmaster EFI - Custom Stainless exhaust - Progressive 412HD rears - Corbin Solo - Polaris Bellmouth - AI removed - 4" Rise "T" drag bars - Custom A/F map - so much more to do!
