Hagon Monoshock Puzzle

[Andy Clap]

So I bought this FZS600 which had a Hagon Monoshock fitted.  I thought the seller just hadn't set it up, but now think it needs re-gassing as the adjuster does not adjust the damping.  I'm pretty sure there is oil in it.


But here's the thing; it's not an FZS600 shock.  According to the Hagon site, it's an YZF R6 unit, which I believe people do fit to the FZS1000?


The bottom clamp/yolk/bracket appears to have been welded on at some point after it left the factory; not a bad job and a million miles better than I could do, but not as  neat as the factory weld on the top clamp/yolk/bracket.


1. Do FZS600 and FZS1000 shocks have the same bottom bracket?
2. How do I test it properly?  With it off the bike and the spring removed there is some resistance to compression and it rebounds in about a second which seems fast.  That is with it the right way up; upside-down it rebounds instantaniously.


Thoughts?  Offers!!!

Anybody?  Do FZS600 and FZS1000 shocks have the same bottom bracket?  :\

As u can see the 1000 bracket is a little longer where it connects to the bottom of the shock.

Many thanks Exupnut.  That blows my theory that somebody has welded on the bottom of a FZS600 shock, looks nothing like it.


Perhaps it is just an R6 unit after all?
