For what it's worth I considered the Ikons and got the exact same $600+ quote from them (I'm in Sydney too), so I started looking at alternatives. That's when I learnt that Hagon bought their plant and designs from Girling who went into receivership in the UK in the mid 80's. If you remember the 70's, the first thing you did was rip off the stock shocks and fit a set of Gas Girlings (well at least in my part of the world you did, so I decided that the simple Hagon's might be in keeping with the period of my newly acquired F1 and decided to get a quote.
I finally bought a set with Chrome springs from Darrell at Moose Head racing here in Aus for $300 AUD. You'll find them here
http://www.hagonoz.com.au/index.htm The CB750 shocks look like those on the left and you can add shrouds for another fifty. The Hagon stickers come off really easy:).
As someone else here said in another Ikon thread, putting a set of Ikons on the stock CB750 frame is a bit like putting a fur coat on a 10 dollar hooker. I don't totally agree and they look mean, but I wonder if the Ikons would be twice as good as the Hagons for twice the price? Maybe when I find the limit I'll upgrade to Ikons, until then the $350 I saved paid for a Boyer Bransden Micro Digital, 4 Keyster F1 carb kits, and 4 x 42mm pods plus change.
