Cylinder kit with 50cc and 40mm bore including fan cylinder head from Parmakit suitable for Sachs 50 S / RS engines. These engines were installed in Hercules K50, KX5, Ultra, Supra, Prima GT, MK Prima as well as KTM Comet and DKW RT 139, among others.
The combustion chamber has been optimized and the compression increased, resulting in a noticeable increase in power and faster gas exchange. In addition, piston windows and a notch in the cylinder liner have been incorporated, which tightens the timing.
Displacement: 50ccm
Piston pin 12mm
Stroke: 39.7mm short stroke
Bore: 40mm
The set consists of cylinder, cylinder head, piston set (piston, piston rings, piston pin, clips) and gaskets.
