Standard piston ring set for the stock bore domed piston on many of the Honda 70cc models. It does NOT fit the flat top piston, see specific fitment below. If you're just freshening up your top end and having the cylinders honed, install a fresh set of rings to ensure a tight fit. Make sure to stagger the ring gaps according to the manual.
Set comes with 4 rings and the oil ring spacer.
Be very careful when installing the cylinder over new rings, it's helpful to have the proper tool to keep the rings compressed as you lower the cylinder over the pistons. Try to use only plastic tipped tools to prevent from scratching aluminum surfaces.
