Rings are the bands fitted on the piston that seal against the cylinder: they hold compression and limit oil getting past.
WISECO offers this piston ring set for KAWASAKI KX 500, SUZUKI LT 500 QUADRACER 2WD and YAMAHA YZ 490 1985-2004. Rings are thin steel bands sitting in the piston grooves. They press against the cylinder wall to hold compression and scrape oil.
The benefits:
Wiseco has forged its pistons in Mentor (Ohio, USA) since 1941 and controls the whole process, from aluminium bar to the friction-reducing ArmorGlide skirt coating. Its pistons are developed with Team Honda HRC in Supercross (450 class since 2018).
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 20 h in hard use and every 40 h for leisure.
Cross-Mania tip: Check the ring end gap in the cylinder before fitting and respect the fitting direction (mark facing up).
