91 zx2r rear caliper piston size

Try and find a guy retailing as "southern cross sports" was very helpful when I needed parts for mine
He was on eBay and I think had a website of some sort....

.... but they all say the rear piston is 34mm, I have measured mine and its 30mm O.D......

did you measure this with the piston actually out of the caliper, or just the face of the piston that you can see when its still in the caliper ?

try the kawasaki balius i have heard they share parts.

also the gpx250/zzr250?? i doubt they had different calipers especially the rear for all their 250's

cant polish the scrape out?

mine were badly pitted and i just polished them and they sealed depends on how deep it is i guess

good luck with it there a hard bike to find parts for but worth it

also call "RB Imports" in NSW they may be able to help you they mainly deal with race bikes but have alot of contacts for imported bikes

Try Powerhouse in the UK, they are on ebay, very reliable & professional, I'll be suprised if they cant help, the last lot came in 4 days.

try checking the part number for your rear caliper on this site

you should find all the relevant part numbers for the piston and seals etc as well. Copy & paste these part numbers into google - you should find a heap of links come up with these part numbers, but they could be from different model kawasakis. This is how you can possibly locate a suitable donor model bike which runs the same rear caliper as yours.....its a long shot but worth trying.

grey imports are a nightmare, they are often a domestic Jap model only and parts can only be sourced within Japan for these. This is one of the reasons that aussie importers for aussie models, refuse to deal with requests for parts for these bikes. Its a nightmare. Good luck with the search though

Is it the same caliper as this?>

pretty sure his rear caliper is a single-spotter, not a twin ?

ooops, Might be more like this one then?>

So that one is the same caliper/brake setup? You can find the same part number/s elsewhere for less more than likely, I have never bought anything from Motosport but I like the layout of the website & looking up part numbers is easy

Email some Kawasaki dealerships (& mention the small flat rate box so they know you know the actual shipping cost) all around & see what they come up with? There is a few on ebay that will get parts in too
