Fan cylinder head for Simson S51, S53, SR50


- for 50ccm, 38mm diameter
- 100% standard contour
- Fine-turned combustion chamber contour for minimal heat loss in the combustion process and against oil carbon deposits. Detonation-reducing.
- Material: Aluminum
- Cylinder head size is specially adapted to Simson cylinders of the M500-M700 series and fits there exactly in terms of dimensions - no oversize or compromises!
- Warp-resistant cylinder head construction
- good sealing properties

Note:
The main focus of the completely new basic design is on maximum heat dissipation in the spark plug area. Only in this way is it possible for the spark plug to maintain and even reach its specified heat value. Thus, the risk of auto-ignition/knocking/engine knocking is much lower, and more advance ignition can be used, which in turn allows for more torque and power.
The good mass distribution of the head ensures excellent heat dissipation to the outermost cooling fins. The combustion chamber remains thermally healthy and the cylinder charge remains cooler. This also has a positive influence on torque and power development.
Reinforcement ribs on the cooling fins provide additional stability and ensure pleasant noise development. The head is no louder than a standard cylinder head. A strong argument when it comes to individual approvals and entries in the vehicle documents.
