The fully forged shaft is manufactured from high alloy steel and hardened 18NiCrMo5 with a special heat process. The full circle design allows a higher pre-compression and thus provides for improved cylinder filling. In the manufacture of the connecting rod in addition, special attention was paid to the load. The connecting rod is forged for solidifying the structure and completely polished or sandblasted surface. It is subjected to the same hardening processes such as the crankshaft, thus guaranteeing absolute low wear in the bearings. The silver needle bearings offer excellent storage and speed are set min to more than 16,000 U /. A perfect, dynamically balanced crankshaft for heavy loads and optimum performance in high-end engines.
