Set of rings Ø64.25 mm for 9481D025 - VERTEX (Manufacturer's reference: 590264250001)
This set of rings is intended for replacement during an engine overhaul on pistons Ø64.25 mm. Offered by VERTEX, this set allows you to restore the piston ring sealing and re-establish the tightness between the piston and cylinder, an essential element for good engine performance after disassembly.
Compatibility (examples): YAMAHA YFZ 350 BANSHEE 2WD (2006 & 2007) and YAMAHA RD 350 (1975). Before installation, check the cylinder bore, the condition of the grooves, and adhere to the clearances prescribed by the manufacturer. Proper cleaning of the grooves and careful assembly minimize the risk of premature wear.
Workshop tips: measure the piston diameter and the ring-groove clearance, respect the orientation of the rings if present, and perform a proper break-in after the first reservice. In case of doubt, entrust the operation to a professional to ensure reliable and durable ring sealing.
