ThanksThis Is the type of piston you don't want
the weak point is the slot in the piston in the oil control ring groove
The stronger type are drilled

Who makes the new stronger type and what are the actual differences? I know that the bike originally came with the dished pistons which translated to a lower compression engine than the higher compression commando type. Here‘s an oddity these pistons of mine measure at the skirt 2.865 a clear 10 thou under the standard 2.875. To be clear the standard piston size should be 2.875 and the bore of the cylinder 4-5 thou bigger than that correct?
So Baz the picture of the piston you posted is broken correct? it looks like a continuous groove behind the oil control ring. Mine looks like this with the rings removed. 4 short slots behind the oil ringThis Is the type of piston you don't want
