Suspension for fat people

Hey people
I was talking to a mate of mine who rides a Harley (or a Massey Ferguson if you ask me) he had a good point about suspension.
My bike being a Japanese bike would be designed for some one Japanese perhaps 60 - 70 kg. I on the other hand am 110kgs, I'm not fat just big boned!
Is there a place that specializes in this or at least does it - that is modify suspension for heavier riders?

cheers
