Diameter: Ø 66.40 mm

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

Diameter: Ø 66.40 mm

PROX offers this piston ring set for KTM EXC 250, SX 250, HUSQVARNA TC 250, TE 250, BETA RR 250, XTRAINER 250 and GAS GAS EC 250, MC 250 2006-2025. 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 / XC-W, Husqvarna TE 250/300 2017-2023):

Racing: every 40 h.
Leisure: every 80 h.
KTM SX, Husqvarna TC 125-300 2017-2022: racing: every 20 h.
