Haven't heard much about Ikon (http://www.ikonsuspension.com/content/application_lists/shock_absorbers/bmw_shock_application.shtml)

Feel free to add your own suggestions to this thread. These are for K1100 applications.

There's Ohlins - then there's all the rest.

Model BM-420 - Fits 94+ K1100s (Won't work on 93 and earlier models because the reservoir would hit the rear ABS modulator.  If your ABS has been removed then you could use the BM-240

There's also one that has both reservoirs remotely mounted (I have one on my 93 K1100LT) but I don't know the model number of that one.

Model S46PR1C1S or BM137/46PCRS - Fits non-ABS K75 and 2-valve K100 models. (Again, the issue is the rear ABS modulator and the shock reservoir wanting to occupy the same space.)

Model BM847/HRCS - Fits ABS K75s and 2 valve K100s.  On this one the reservoir is mounted to the rear to accommodate the ABS modulator.

Progressive Suspension also makes two models of shocks for K75s and 2 valve K100s.  They're a decent shock and, though not the best, a darn sight better than the stock shocks on those bikes.

Hagen used to make shocks for BMWs too but I don't think the company is around anymore.

Fox Shocks made "twin-clicker" shocks for both 2 valve and 4 valve K bikes which are a pretty good shock but I think they've moved on are out of production on those.  You can find them occasionally on Fleabay.

OK Ohlins is the best but when I verified the price I almost wet myself  :o

I just looked at my rear shock today, and noticed the gasket inside the shock floating around.

Today is not the day I going to drop big cash for a shock. Maybe tomorrow, but not today  ;D

Can the stock shock be rebuilt?


Bike is riding fine, but I suspect the rear shock will need replacing some day.

I have been looking at this:

(Scroll down -- next to the first image is Economy Monoshock for K75 and K100.)

Any opinions?

Thanks

Bill

The K1 I bought this spring came with a Hagon on it.  Seems to ride fine.

I have a hagon on the K75 and it is good but rides a bit harsh.

Probably too high a spring rate.  With a Works or Realm you can order the right spring for your normal riding weight. (Rider/passenger/gear)

I have had some others say that the Hagon shocks are like that, they seem to over spring them.
The Ikon shocks are made in Oz and from what I have seen recently the quality is nowhere near as good as it used to be on the old Koni. I personally know of 3 in my area that have gone back for claims. One the spring lost its tension the second fell apart when the guy lifted it onto the centre stand and the other was crap damping right from the start and was replaced by the dealer.
