I need oversized pistons for the project engine NC42 or NC31. The differ in compression height but in my case it doesn't matter.
I don't want to use chinese pistons "AHL" as I don't trust it and didn't find any reports about the use. Especially fir rings.
I know there should be original pistons and rings but can't find the part numbers.
13101-MCE-000 <- piston
13011-MCE-305 <- rings

So it should be
13102-MCE-000 <- piston + 0,25
13021-MCE-305 <- rings + 0,25

Am I right? Or do some 55-58mm pistons with 14mm pin exist for 12000 RPM engines exist? FZR400 pistons are OK but 15mm pin makes it hard to use, no way to change the conrod

David Silver and John Oldfield are large Honda parts stockists in the UK, the part number for the piston you posted doesn't come up for David Silver:

however there are various pistons at +25 listed here:

if you search for 13102 they appear to be in that area. Maybe that helps.

I love the Kandy red you have painted your body work, I didn't go Kandy for mine as too scared of having to re-paint the lot for one scratch...

Thank you a lot for the links, will check it out carefully.
And about the paintjob - we live to make our dreams come true, so... it's the bike I wanna ride, it's worth it, I'm sure. Just add turbocharger - it's my branded seasoning =)

At last I've bought original STD pistons and will replce liners.
turbo go go
