VERTEX offers you these replacement piston rings in Ø89mm for KTM and BETA 4 strokes. This includes the complete set of piston rings with 2 compression rings, 2 protection rings and the oil wiper. We recommend to change the piston rings every 20 hours or 8000 km to avoid any compression loss. As a reminder, it is preferable to also change the seals when reassembling your cylinder on your engine to ensure a perfect seal.
