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

      • Diameter: Ø 66.40 mm

      PROX offers this piston ring set for YAMAHA YZ 250, YZ 250 X, SUZUKI RM 250 and FANTIC XX 250 1999-2027. 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 PROX?

      ProX has its pistons made in Japan and the USA, with Japanese rings (Riken, TP or NPR) and tolerances at least equal to OEM; most of its four-stroke pistons are forged.

      When should you replace the piston rings?

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

      Recommended hours for new rings (manufacturer recommendation for the Yamaha YZ 250 two-stroke):

      • Racing: every 7.5 h (about 3 races).
      • Leisure: no Yamaha figure; Cross-Mania guideline: compression check at around 15 h.

      Specifications and fitting tips

      • Manufacturer part number: 02.2319

      Cross-Mania tip: Check the ring end gap in the cylinder before fitting and respect the fitting direction (mark facing up).
