PROX offers this piston ring set for YAMAHA YZ 85 2001-2027. 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 15 h in hard use and every 30 h for leisure.
Cross-Mania tip: Check the ring end gap in the cylinder before fitting and respect the fitting direction (mark facing up).
