quite true, the sachs in standard form i found to be great for off-road (read flat out open stuff) but really sucked for the tight slow rocky stuff that i want to ride. After a twowheels revalve it is now great ... and once the fork is "fixed" the shock rears its head as the next weak link
+1
In the 2011 shock has a straight stack and can be made to work over more varied terrain with a 2 stage stack, as can the fork! With some mid valve care
Stock valving will almost always need to be changed for the rider/ conditions, no matter what brand of bike/suspension it's just that Sachs seem to not get even close out of he box compared to other gear, Showa on an rmz250 is nicer for trail riding straight out of the box, and it's an mxer......just wind out the clickers.
When Sachs is seen to, it's as good as anything in its class.
That means the forks are always going to be open chamber CLASS and spook you on fast, rough downhills like wp, marz, and kyb open chamber gear because the oc design finds its limitation there, not the brand. I've had it with oc forks.
The shock is as good as anything I've ridden now I have it valved the way I like it. Today I put back the check valve and apart from it starting to groan ( I'm going to buy a terry hay rsv to replace it) i loved the feel, the whole design of the shock and the results you get are absolutely great, as you would expect from a gas pressurized res. shock. It's not a limited design like the forks.
de carbon piston or bladder?.... Meh it's so close as to purely be a convenience with the bladder re servicing.
Seeing the new wp twin chamber design, I reckon you will not see oc forks on anything serious as of 2014, coatings and seals areas e point where stiction is no longer an issue, and ktm reckon there is no longer a cost difference.
All IMHO.
