Rings are the bands fitted on the piston that seal against the cylinder: they hold compression and limit oil getting past.
VERTEX offers this piston ring set. 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 two-stroke pistons are cast from an 18 % silicon alloy. Its four-stroke pistons are forged from 2618 alloy.
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.
