Hi All, }I just wanted to post that my store (greyimportspares.com) is investigating a custom run of zxr250 A model (48mm) piston kits. We are also investigating Oversize kits as well. Minimum run is 24 and each kit is per cylinder. kit includes piston, rings, circlip and pin. Oversize kits we are investigating are 0.5mm and 1mm. Kits are $172 each. if anyone is keen, please email me (sales@greyimportspares.com.au) Kits are to be made by Wossner in germany. They are a very reputable company who make many aftermarket kits for road and dirt bikes. We will also be looking at other bikes if this is successful as we know there are a bunch of MC-19 and MC-22 owners needing pistons as they are no longer being made. Cheers Aaron
