    Sxr piston replacement

    skidaddy o - Today 01:31 AM Report
    I need to put a new top end in my sxr 800 which pistons should I go with I'm looking for a long lasting reliable piston versus a high performance race piston that needs to be replaced often thanks people please respond also how do I know which size I need they have never been replaced and its a 2005 I'm replacing because the front cylinder is reading 150 and the rear like 145 on the compression tester

    The only way to determine which size to order is to pull the head and look at the damage. Measure the diameter with a micrometer and go from there. To go oversize, you'll have to get the cylinders bored to match the new pistons.

    I don't think that is a large enough variation to warrant a rebuild. Usually less than 10% is acceptable.

    It doesn't sound like you need a top end, but to answer your question, I would go with Pro-X pistons. They will last longer than the wiseco or any other forged piston.

    Second that mate pro x if you are not racing !
    If it a 05 I would pull the head have a look 82.25 is the next size up or put some new rings in it !
    Something that's 8 years old I would be happy to bore it
    It might save you a case rod or cylinder down the track !
    My 2 cents 😉
