The 4.3 litre EGMO Signature Engine represents one of the most important technical pillars of the Erbacher brand. Developed in partnership with EGMO, this engine is based on the original 964 engine platform but significantly re-engineered. With specially cast cylinders, Swiss-made cylinder heads, proprietary engine management, and an individual throttle body system, the engine produces approximately 409 to 430 horsepower while maintaining the character of an air-cooled flat-six.
