Evotech do some nice hangers. I'm thinking of getting some myself.

I don't think you will need a rubber mounting if you remove the footpegs.
The rubber bush in the rear footpegs/hanger is most likely to minimize vibes in the passengers feet.
What about the vibes through the sub frame and in to the seat of your pants?...:dunno
Can't see it being a big issue, you will get far more vibration from the engine into the frame, and the seat foam (is there any ) should absorb it.
The Akra's on my Tuoldo had no rubber bushings and I never noticed anything.
if your hangers have them, it isn't a problem, but it equally isn't something IMHO that you should worry about. :dunno
Is there no rubber bung in them? Would you feel the vibes through the exhaust? could be a real pain on a long journey and at that sort of money you'd expect a rubber mounting.
I just bought a pair from rsvblue, not sure what make they are but they do have a rubber mounting, you could pm him and ask where did he get them from. Check out his pic, I think it's back on page 2 for sale section on rsvzone.com
