Restore compression and bring back crisp 2-stroke performance with the Wossner Piston Ring Set (RSB7200). This replacement ring set is built for a precise 72.00 mm bore and is ideal when you’re servicing a top end, fixing low compression, or refreshing power delivery after hours of riding.
Fresh piston rings help improve sealing between the piston and cylinder, which can translate into easier starting, more consistent throttle response, and reduced blow-by—making your engine feel tighter and more reliable.
