There seems to be a bit of confusion which should be clarified, I find that the measurements would be tight compared to the OEM specs but the Wossner runs a coating which is supposed to wear down to get to the correct clearance.
Quote from the Wossner technical piston installation guidelines:
"Wossner performance coated pistons require no adjustments to nominal piston to wall dimensions. The coating is intended to wear into the cylinder wall, and no additional clearance should be calculated for installation. Coating thickness can be .02-.025mm (.0007 - .0010”) total build up to skirt diameter"
I have run the 8100DA piston in my 2004 CR125 and it has over 20 hours on it and runs great!
Piston was beautiful and very well made. Issues arised when trying to install in a new oem cylinder. Clearance was not correct on piston. Piston measured larger than an oem cast piston. Would not recommend this piston with a new oem cylinder. Would be great for cylinders that are being replated or sleeved. Oem cylinders are not manufactured to 54mm so that is where the clearance issue arises. Ending up going oem and putting this piston on the shelf :(
