Kawasaki KX125 2003-2007 Athena 144cc 58mm Big Bore Cylinder Phathead

Phathead Kits provide a two-stroke big bore kit with a head shell, nuts, washers, stickers, and installation instructions. The cylinder heads are made of 6061 T6 billet aluminum, offering improved heat transfer and cooling.

• The material is stronger and transfers heat better than cast aluminum.
• The two piece design allows an increase in coolant flow as well as surface area which improves cooling for better consistency and performance.
