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

Diameter: Ø 95.00 mm

PROX offers this piston ring set for KTM EXC 450, EXC 500, EXCF 500, SMR 450, SXF 450, HUSQVARNA FC 450, FE 450, FE 501, FS 450, HUSABERG FE 390, FE 450 IE, FX 450 and GAS GAS MCF 450 2008-2025. 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 SX-F, Husqvarna FC 2016-2022):

Racing: every 50 h.
Leisure: no KTM figure; Cross-Mania guideline: compression check at around 100 h.
KTM EXC-F, Husqvarna FE 2017-2023: racing: every 70 h.
