    This is the first time I've ordered a piston from this site, and I have to say that I'm clearly not disappointed. The piston is in very good condition, there's no trace of scratches or anything else, plus everything is very well packaged, nothing to say on that score, and the rings fit superbly, they're not damaged or broken at all, nothing at all. I'm going to put this on my Masai scrambler 50cc with a 70cc cylinder kit.

    I will say yes! Piston like a piston big differences are not, but you need to remember that the pin enters only on one side of the piston
