Not having seen such a seat, it sounds OK.
I think outdoorgb is on the right track. What you may be experiencing is a higher than normal vibration from the rear of the bike. You should, as he says, check the chain thoroughly for both condition and tension.
I had a chain on my '08 that went south. It created all kinds of odd input, to the point where I thought my clutch was going bad. Check especially the rollers. They should not be sloppy or loose fitting. Check them in several places on the chain. They don't all wear evenly. If you've got a bad section of chain it could set up vibrations at certain road speeds.
I would also start looking at the tire - what sort is it? If it's a knobbie, well, they buzz. Look for chunking, cupping, bulges, etc. Eyeball the alignment (measure from the centerline of the swing arm pivot to the centerline of the axle on both sides rather than trusting the 'alignment marks') with a tape measure.
You say there is no buzz in the handlebars or foot pegs, but how well can you see out of your mirrors?
Do you know anyone with a different seat that you can borrow? Any seat from the last 25 years will work.
How many miles on this bike?

On the way downtown I stopped at a bar and had a couple of double Scotches. They didn't do me any good. All they did was make me think of Silver-Wig, and I never saw her again.
'How' are words so important they cannot be too often used.
