ZZ.21C Ceramic Long Stroke Nitro Competition Engine
The LRP ZZ.21C Ceramic Long Stroke exclusively made by O.S. Engines is the successor of the internationally very successful ZZ.21.Ceramic Spec.2. More precise response characteristics in the lower RPM range and less fuel consumption were the goals in the improvement of the power aggregate.
This could be successfully implemented with a special, new developed crankshaft. The 14.0mm strong crankshaft has a DLC coating as well as a silicone insert. It is also precision-balanced just like its predecessor and works very smoothly in combination with the ceramic bearing.
Due to the reduced fuel consumption, a longer run time and a more controllable performance development could be realised.
