Dennis,
Know what you mean about the Speedy having the edge on the America, black an all that - go for it.
Seat wise I've got a single with seat pad - no complaints from the pillions. The stock double is not good for longer journeys, but the touring seat will do the trick.
I've also put on a full Triumph screen which takes out the majority of wind buffeting, makes all the difference on the motorway.
Get a Bonny swap out when mine's in for service and after I've extracated my legs from up my backside, can't wait to get back on the Speedmaster.
