Most two strokes {road and race}  in the uk run  Mitaka piston
 I Used to use them back in the 90s on a proddie 250s never had any issues
Most tuners in the uk  build motors with mitaka pistons http://www.fastbikesmag.com/files/2011/01/FBK238.ftwo_.pdf

D'ont think they make pistons for the kx5 but i was tempted to try one on the cr500
I have used there rods on kx but have not done enough hours to say how good they are

I Personally would prefer to use a genuine s4 rod  as it has  individually roller bearings on the big end and 3 lub holes on the small end side
Most aftermarket rods[inc wossner} have a 1piece big cage/bearing [far less roller surface exposed to oil}and only 2 oil holes on small end side

I bought a basket for my 250 but nothing to report on yet. The machining quality looks good and the anodising is smooth and even.

As said my experience with Wössner is not KX related it's race car related , in this world Wössner is seen as B quality to put it mildly

For example compared to Mahle the piston quality is much much less they have to spray the coating to get a acceptable piston clearance , after a few hours the coating is gone....
We had pistons which had the pistonpin desaxation to the wrong side.
The conrods are breaking  the finish is terrible and the dimenstions are questionable therefor they all need a rebore to get it the bore's , lenghts and straightness right , I got one set out of a engine we got in which I didn't even dare to use.
