Set of Piston Rings Ø66 mm VERTEX for HONDA CRF 150 2007-2027

VERTEX offers this piston ring set for HONDA CRF 150 2007-2027. 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 HONDA CRF 150?

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 Honda CRF R / RX / X):

• Racing: every 15 h (about 6 races).
• Leisure: no Honda figure; Cross-Mania guideline: compression check at around 30 h.
