Where can i get 85mm Pistons for my SXR?

[millsi]

G'day from Australia, I'm trying to find some 85mm pistons to go in my SXR but not having any luck with Google. Seem to be only available as part of a kit.
Wiesco distributor in Australia doesn't have a listing.
Thanks

they are not listed as SXR pistons, they are listed as big bore 750 pistons. call around, you can find them. They were blowing them out at Havasu this year

I believe GroupK would be able to help you with those pistons.

 

[user_error]

they are just standard wiseco pistons, any vendor should be able to get them.

Make sure you get big pin 85mm pistons and not small pin.

I think the problem is the SXR is a bit of an orphan here in Australia. Pretty much everyone rides superjets. Maybe one reason why the wiesco distributor cant get them. My bore is pretty badly damaged and I don't think 83 will be big enough to get rid of the damaged surface. Once I go past 83 I will probably need to get my head modified or get an aftermarket. Have decided to go with the ADA v2 girdled head which can take both 83 and 85mm domes.
Looks like tomski has come to the party with some 84.5s.
What sized domes should I be I be looking at, to run on pump fuel? Our 98 octane is comparable to your 93 octane I believe. Porting is standard

I just bough a set of 85mm Race Pistons from Group K recently. If you are boring out the standard cylinder I would take it out to a 820cc. Once you go bigger than that you really need to re-Sleeve the Cylinder as the sleeve is very thin and made of poor quality steel.

You can easy go to 850 without resleeves just let it done and going for 850

If shes stock class you should be right but anything making power will crack the standard cylinder. Good Luck with that.
