Description
This Wossner piston kit features a 100mm bore and is designed as a standard replacement for high-performance Ducati engines, specifically the 998 Testa Stretta Racing and 999S models. Forged in Germany, the piston is engineered for optimal strength and efficient heat transfer from the combustion chamber to the cylinder walls. Its elliptical design ensures even load distribution and prevents localised stress, enhancing engine durability under high-performance conditions.
