VERTEX piston ring set Ø 54.00 mm for TM RACING ENDURO 125 2T, GAS GAS TXT PRO 125

Check before ordering

• Diameter: Ø 54.00 mm

VERTEX offers this piston ring set for TM RACING ENDURO 125 2T, GAS GAS TXT PRO 125, HUSQVARNA CR 125 and YAMAHA YZ 125 from 1990 to 2016. 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.

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 CR 125 R / CR 250 R):

• Racing: every 7.5 h.
• Leisure: no Honda figure; Cross-Mania guideline: compression check at around 15 h.

Specifications and fitting tips

• Displacement: 125 cm³
• Engine: 2-stroke
• Replacement piston ring
• Nitrided or chrome-plated for improved wear resistance and longer life

Cross-Mania tip: Check the ring end gap in the cylinder before fitting and respect the fitting direction (mark facing up).
