Sorry, currently out of stock
Please always send us a photo of the ones that are in your specific Moki. There are many different generations of them and we need to match the version and more importantly, the weight of the piston to the ones already in your motor.
Some have cutouts/windows, some do not, please check as you need to maintain the balance of your setup. You can always lighten up a heavier piston by taking away at the flanks.
