Rings are the bands fitted on the piston that seal against the cylinder: they hold compression and limit oil getting past.
PROX offers this piston ring set for YAMAHA WRF 450, YZF 450, HUSQVARNA SMR 510, SMR 510 I.E, TE 510, TE 510 I.E and FANTIC XEF 450, XEF 450 RALLY, XXF 450 2005-2027. Rings are thin steel bands sitting in the piston grooves. They press against the cylinder wall to hold compression and scrape oil.
The benefits:
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.
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.
Cross-Mania tip: Check the ring end gap in the cylinder before fitting and respect the fitting direction (mark facing up).
