    Rings are the bands fitted on the piston that seal against the cylinder: they hold compression and limit oil getting past.

      VERTEX offers this piston ring set for YAMAHA WRF 400, YZF 400 1998-2000. Rings are thin steel bands sitting in the piston grooves. They press against the cylinder wall to hold compression and scrape oil.

      Why replace the rings?

      The benefits:

      • Regain compression and power.
      • Reduce oil consumption and smoke.
      • A cheap fix when piston and cylinder are still within spec.

      Why choose VERTEX?

      Vertex has made its pistons in Italy since 1953 and has supplied KTM’s original pistons since 1996: molybdenum-disulphide coated skirt and Japanese rings. Its four-stroke pistons are forged from 2618 alloy.

      When should you replace the piston rings on your YAMAHA WRF 400?

      Harder starting, loss of power, blue smoke, oil consumption or a knock when cold: these are the signs of a tired top end.

      No manufacturer hour figure for this model. Cross-Mania guideline: compression check every 30 h in hard use and every 60 h for leisure.
