I didn't really know the history of the Hagon shock that came with the BMW K100, but I DID know that to adjust the preload it was necessary to take the shock off, remove the spring & then clean everything up and smother in grease. And it is still bloody hard work.
A quick STFHagon site we find that it is not rebuildable and a new one is about £300. + P&P
For once my Google-Fu was in tune with the rhythms of the earth and quickly lead me here...

Where I find someone making variable damping billet alloy shocks ONLY for K series Beemers. And at rather less than £300. A quick call assures that the peeps at the other end of the line are reasonably serious. They want to know EXACTLY which K bike you ride, what you weigh, what the luggage weighs, your riding style, that sort of thing.
And having answered all this the shock arrived within two days.
Comes with stainless fasteners, shims, C spanner & fitting instructions.
Goes on a treat (although a rain stoppage caused the first run out to be interesting as the damping was turned right down as per the fitting notes). I have set the sag to 25mm ish. (Suspension travel on the RS should be 110 mm. RAM suggest setting it up by eye but I'm a bit old fashioned. And I like to have a measured base line to work from). And
the damping at 4/12. A fast ride to Cambridge via the notoriously bumpy Fowlmere road suggested that 5 or 6/12 might be a slightly better setting and POSSIBLY a tad more pre-load. But apart from that it has been simplicity its self. It seems a good unit. It appears very well made and it even looks quite pretty
I commend the gentlemen at RAM to the house.
