KDX125 piston - dimension confirmation

James P · Post by **James P** » Wed Mar 27, 2013 7:50 am

I have the drawing showing the dimensions of the Wossner KDX125 piston, which was kindly posted on this forum. It shows the radius of the crown to be 113.75mm.

Can someone confirm that the crown radii of the KDX125 pistons (both OEM and Wossner) are the same as the OEM KR1/KR1S piston??

Thanks & regards,
James

Thanks for that info Jan. I have found both NOS OEM pistons on the internet (i.e. only one of each KR1S and KDX125). If/when they arrive, I will compare the dome radii using my custom-made super accurate

cardboard radius gauges (these are made from your favourite gasket material - cereal packets

)...!
