Prox piston from which model?

Can source prox pistons locally in NZ but I don't think they have a direct replacement for the KR1/s. Is anybody able to supply the donor bike or part nos for this please?

(Suspect the KX125 but have seen something from that era that has a flat top piston...perhaps the RGV piston is the same, as the 300 kit from SS had the RGV application sticker on the box felt tipped. Only diff was the exhaust port lube holes in the piston.)

I seem to remember that Prox do a direct replacement for the KR1S piston

. I know swveral companies do and I sure Prox is one of them. Check out there on-line catalogue, they just may not list it on their Ausie site if the bike wasn't officially .

have checked the website and the local supplier but no on has a listing....sent prox an info request but haven't seen a response from them. Noticed the conrod kits are not a direct replacement either donor bike is the KX125.

The KR1 con rods are the same as the KDX200/220 but these are also an uprated material so make a decent upgrade on a KR1S.

A few years back Stan Stephens supplied Prox pistons, not sure if he still does though.
