ATHENA Piston Ring Set Ø95 mm for KTM EXC, MXC, SX 520, 525, BETA RR 525 and GAS GAS ECF 450 2000-2009

ATHENA offers this piston ring set for KTM EXC, MXC, SX 520, 525, BETA RR 525 and GAS GAS ECF 450 2000-2009. 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 ATHENA?

Athena, the Italian manufacturer founded in 1973, is an original-equipment supplier to manufacturers such as KTM and Ducati: the same standards for your replacement parts.

When should you replace the piston rings on your KTM EXC 520?

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 50 h in hard use and every 100 h for leisure.
