The kit containing every gasket needed to strip and rebuild the top end (cylinder and head) without leaks.
ATHENA offers this top-end gasket kit for YAMAHA YZ 85 LW, YZ 85 SW from 2019 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 ATHENA?
Athena, original-equipment supplier to KTM and Ducati from Italy, laser-cuts its gaskets from materials designed for heat, oil and coolant.
When should you replace the gaskets on your YAMAHA YZ 85 LW?
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.
