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 HUSQVARNA CR 125, SMS 125, TC 125, TE 125, WR 125, HONDA CR 125, KAWASAKI KX 125 and HM CRE 125, MOTARD 125 1980-2025. 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 WISECO?

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).

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 a top-end rebuild (manufacturer recommendation for the KTM SX, Husqvarna TC 125-300 2017-2022):

Racing: every 20 h.
Leisure: no KTM figure; Cross-Mania guideline: compression check at around 40 h.
Riding in sand: every 10 h.
Honda CR 125 R / CR 250 R: racing: every 7.5 h.
