Check before ordering

• Diameter: Ø 96.00 mm

PROX offers this piston ring set for HM CRE 450, CREF 450, MOTARD 450, HONDA CRF 450, CRF 450 X and KAWASAKI KLX 450, KXF 450 2002-2019. 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 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.
• Kawasaki KX 250 F / KX 450 F (four-stroke): racing: every 15 h (about 6 races).
