PROX top-end gasket kit for YAMAHA YZ 65 from 2018 to 2026

PROX offers this top-end gasket kit for YAMAHA YZ 65 from 2018 to 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 PROX?

ProX, the Dutch engine-parts specialist since 1975, has its parts made in factories that also supply the manufacturers: OEM quality at a more affordable price.

When should you replace the gaskets on your YAMAHA YZ 65?

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.
