    780 stock piston or oversized?

    I recently bought a SLX 780 that has a damaged piston and I was wondering how to tell what size of piston it is. I am assuming it will be a measurement taken with callipers but does anyone out there know what the stock size is and maybe the next couple of sizes bigger.

    Thanks
    Jason

    Your machinist should be able to measure and tell you what oversize to buy.

    I was hoping to be able to find out what size it is now because I am hoping it is standard because I am going to have to replace one of the cylinders and if it was standard then that would be great.

    78A .25 is .25mm OS

    78A .50 is .5mm OS
