Converting a Sachs shock to fit a bladder?

[Keg]

Has anyone fitted a bladder to a Sachs shock like you can do to KTMs???? It currently runs a piston and I have not been happy with the o-ring life of it so far.

I know racetech do a 46mm diameter bladder in 88mm long which should work. But I believe it is for a KTM so has a screw on end. I can machine the thread down and fit a circlip ring grove to make it fit.

That way it should be more reliable, easier to bleed up and slightly better in performance.

Anyone done anything like this???

Moto-Pro suspension has one. See

I used one of their bladder kits on my daughter's KTM, and it was really nice, high quality, and easy.

I also used their kits to revalve the forks and shock on my old XR250. It's a great outfit.

I suspect another problem is at hand. I've had no failures with Sachs, Ohlins or WP shock piston o-rings over the last eight years.

It did have a little bit of swarf-like metal fleck in the o-ring. The bore and piston are un-marked.

The only thing on their web site is the KTM one? Is this the same?

I have tried to call Pro-moto but their were not there at 3:30pm Pacific time? Are they open this week?

Keg,

That's a bladder for a KTM. The bladder kit they sell fits inside the stock shock body and replaces the piston with a bladder. If it's not on the website call or email them.

with the bladder in the bike feels just that bit softer or you might say plusher. It might be just retail therapy but it seems a worth while mod so far.

That MAY be a placebo effect, because you spent $$ and expect results.

My Sachs is just revalved and its absolutely the best suspension I have ever ridden in rocks and trail trash. In my never ending quest to get KTMs to feel decent when I rode them, the bladder conversion made no difference. IMO, the leverage on that shock during the initial travel will overcome any stiction that piston o-ring may cause to the point of it being a non-issue. Have you ever noticed the stiction of the linkage when its torqued down with a fresh set of o-rings? It seems scary stiff but makes no difference in performance. Forks are another matter because they are not progressive.

Tuners like the bladders because they make it eaiser to service the shock. Like Dave said if you have had o-ring problems there are other issues at hand.
