Cylinder and piston KIT YAMAHA YZ450F D.98 06-09

ATHENA has developed a new standard diameter kit that replaces the original cylinder and piston with a BOLT-ON version, meaning that it can be installed without modifications to the crankcases.

The gaskets have been developed using latest generation technologies;

in particular the multi-lamellar head gasket is characterized
from a new system of reliefs that guarantees a perfect seal even at high temperatures.

The nickel plated cylinder is combined with a new lightened forged piston.

Thanks to the high quality standards of ATHENA and a new method of
production, which involves the use of numerically controlled machine tools, the kit guarantees a truly unbeatable quality-price ratio.
