• The fully forged shaft is manufactured from high alloy steel and hardened 18NiCrMo5 with a special heat process. The full cheek design allows a higher pre-compression and thus ensures better cylinder filling. In the manufacture of the connecting rod in addition, special attention was paid to the load. The connecting rod is forged and complete solidification of the surface structure of polished or sandblasted. It is subjected to the same hardening processes such as the crankshaft, thus guaranteeing absolute low wear in the bearings. The silver needle bearings provide 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 motors.
