Set of Piston Rings Ø99.2 mm VERTEX for POLARIS OUTLAW 500, PREDATOR 500 2003-2007

VERTEX offers this piston ring set for POLARIS OUTLAW 500, PREDATOR 500 2003-2007. 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 VERTEX?

Vertex has made its pistons in Italy since 1953 and has supplied KTM’s original pistons since 1996: molybdenum-disulphide coated skirt and Japanese rings. Its four-stroke pistons are forged from 2618 alloy.

When should you replace the piston rings on your POLARIS PREDATOR 500?

Harder starting, loss of power, blue smoke, oil consumption or a knock when cold: these are the signs of a tired top end.
