Forged Aluminum Piston (Defric-coated)
These forged pistons have complex shapes and are used in high-performance engines.

Forged Aluminum Piston (Defric-coated)
Forged pistons used in high-performance motorcycle engines are thin-walled and lightweight, and thus feature many strengthening ribs that require very complex die shapes. To extend die life, extensive stress analysis is performed during pre-production to devise stress-reducing shapes that also make it possible to significantly reduce piston weight. The application of a Defric coating reduces the piston's wear coefficient, thereby enhancing break-in, preventing scoring and reducing friction.
