Athena 08-14 Kawasaki KFX 450 R 99.95mm Big Bore Cylinder 4T Forged Racing Piston

Athena has been a leader in motorcycle spare parts for over 40 years, and they've brought that expertise to their new line of 4-stroke off-road forged pistons. This particular piston is a big bore, measuring 99.95mm, designed for the 2008-2014 Kawasaki KFX 450 R. It's built using a reverse extrusion process and advanced CNC machining, which holds dimensional tolerances to less than 0.01 mm. This precision ensures a solid fit and consistent operation.

The material is a special high-performance alloy blend of nickel, silica, and aluminum. This combination is chosen to give you the same level of reliability you'd expect from an original equipment piston, but with added resistance to stress and excellent performance gains. The piston's surface is finished to be perfectly smooth, which helps promote regular airflow and proper flame propagation within the cylinder for more efficient combustion.
