Diameter: Ø 78.00 mm

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

Diameter: Ø 78.00 mm

PROX offers this piston ring set for KTM EXCF 250, SXF 250, HUSQVARNA FC 250, FE 250, GAS GAS ECF 250, MCF 250 and KAWASAKI KX 250 2013-2025. 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 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 a top-end rebuild (manufacturer recommendation for the KTM EXC-F, Husqvarna FE 2017-2023):

Racing: every 70 h.
Leisure: every 135 h.
KTM SX-F, Husqvarna FC 2016-2022: racing: every 50 h.
