AIRSAL offers this top-end gasket kit for YAMAHA WR 125, WR 125 X 2009-2026. The top end is the cylinder, piston and cylinder head. When they are taken apart, the gaskets sealing them are crushed and cannot be reused.

Why buy a complete kit?

The benefits:

• Every top-end gasket in one part number: nothing is forgotten at reassembly.
• Cheaper than buying the gaskets one by one.
• New gaskets guarantee compression and sealing against water, oil and gases.

Why choose AIRSAL?

Airsal, the Spanish two-stroke cylinder specialist since 1986: aluminium cylinder with a nickel-silicon-carbide coating, far more wear-resistant than cast iron.

When should you replace the gaskets on your YAMAHA WR 125?

An oil or coolant leak, seepage around the cases or a loss of compression signal a tired gasket. Having the kit to hand means the bike is never stuck waiting for one missing gasket.
