On ebay it's 0.5mm, 1.0mm, 1.5mm and 2.0mm oversize on mitaka pistons
but on PJME after 1.0mm it's bore sizes like 57.65 and 58.15

why? :s

Bore sizes are different to piston sizes.

yes I know, but "56.50mm bore or 0.50mm oversize" and so on, and after "57.mm bore or 1.00mm oversize" its more weird sizes than the ones on ebay

and those sizes were all bore sizes
