Fan cylinder head Ø38 mm, 100% standard contour - Simson S51, S53, SR50

Fan cylinder head for Simson S51, S53, SR50 - for 50ccm, 38mm diameter - 100% standard contour - finely twisted combustion chamber contour for little heat loss in the combustion process and against carbon deposits. detonating. - Material: Aluminum - Cylinder head size is specially adapted to the Simson cylinders of the M500-M700 series and fits exactly there in terms of dimensions - no oversize or compromises! - Resistant cylinder head construction - Good sealing properties Note: The main focus of the completely new basic construction is the maximum heat dissipation in the spark plug area. This is the only way the spark plug can be maintained and achieved at all. Thus, the risk of self-ignition/ringing/engine knocking is much lower, you can drive more early ignition, which allows more torque and performance in reverse. 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 effect on the torque and power development. Reinforcement bars on the cooling fins give additional stability and ensure pleasant noise development. The head is no louder than a standard cylinder head. A good argument when it comes to individual acceptances and entries in the vehicle documents.
