ATHENA Complete Gasket Kit (with Crankshaft Seals) — gasket set designed for complete engine reassembly. Provided by ATHENA, this kit includes everything essential for replacing engine sealing during a service or restoration: case gaskets, interface gaskets, and, in particular, crankshaft seals for the lower engine.
Ideal for riders and mechanics refurbishing a Cross engine block, this kit simplifies reassembly by eliminating the need for back-and-forth trips to find the correct part number. The included lower engine crankshaft seals ensure sealing at the crankshaft exits and help minimize oil/oil-engine leaks when installed and adjusted according to manufacturer specifications.
Examples of compatible motorcycles (to be verified according to model year and specifications): YAMAHA YZ 125 (2026), FANTIC XX 125 (2026), FANTIC XE 125 (2024). To ensure lasting sealing, adhere to the torque specifications and installation recommendations from the manufacturer when fitting the gaskets.
