Had a look at the suzuki site, in particular gt750, there isn't really that much there, no fuel tanks, exhaust pipes etc, just little bits and bobs, I'd say at a guess that Honda can still provide more parts per bike across the range. All suzuki seem to have done is found what some of their modern bikes use and what fits the older stuff, renumbered the parts and jacked the prices up!
