YBR125 motorcycle valve oil seal, size and YBR125 intake and exhaust valve rod fully match, directly replace the crude oil seal without adjusting the gap; Fluorine rubber material, oil corrosion resistance, high temperature resistance (suitable for the high temperature environment of the engine room), long-term use of no aging, no cracking; Built-in spring + double seal lip structure, closely fit the valve rod, effectively prevent oil leakage into the combustion chamber, avoid burning oil problem; Including inlet and exhaust valve oil seal each 1, one-stop equipped valve chamber sealing parts, save the trouble of separate procurement; Good sealing effect reduces oil consumption, avoids carbon deposition in combustion chamber, and ensures stable engine power output.
