Product Information "Tuning cylinder kit ZT63N Stage 1 (63cc) - for Simson KR51/1 Schwalbe, SR4-2 Star, SR4-3 Sperber, SR4-4 Habicht"

ZT63N Stage 1 cylinder kit


For a long time, there were very few more powerful cylinders available for the KR51/1. This is due to unfavorable channel routing and the fact that higher-performance kits quickly reach their thermal limit. With only 2 oversize pistons, the durability of such gray cast iron cylinders was also limited.
The cooling body and the running sleeve are made of high-quality aluminum casting. The running sleeve is coated in a special process, making it extremely robust and providing optimal protection against wear.
The thermal conductivity is also significantly higher than with a cylinder variant with a gray cast iron sleeve. In addition, the heat dissipation is further improved by a blasted, slightly rough surface.
Thus, the two core problems have already been eliminated through the use of new technologies.
The timing and channel cross-sections have been designed for high torque from low RPMs and a wide power band to harmonize perfectly with the 3-speed gearbox. This means that the drivability from low RPMs is absolutely identical to our "old tuning cylinders". In addition, however, the power in the middle and upper RPM range has been significantly increased, resulting in a power band and power development that is otherwise unmatched in this class.

Features:
- Original look cylinder with coated aluminum sleeve
- High-quality material for cooling body and running sleeve
- Improved heat dissipation through blasted surface and coated aluminum sleeve
- Long durability, approximately 10,000 km per piston (multiple oversizes available)

ZT63N Stage1

Absolute Empfehlung. Das Kit läuft super. Die Verarbeitung und der Guss sind sehr hochwertig. Nach Abnahme bei der DEKRA auch legal zu betreiben ;-)

Unauffälliger Zylinder für die Schwalbe

Hat ordentlich Dampf und somit macht die Schwalbe fahren noch mehr Spaß. Ließ sich einfach verbauen, Quetschmaß konnte man auch super durch die mitgelieferten Dichtungen anpassen, vollkommen zufrieden.

Zylinderkit im Original Look

Der Zylinder ist optisch sowie vom Material sehr gut verarbeitet. Die Einzelteile waren sicher verpackt sodass nix beim Transport kaputt gehen kann.

Alles super und läuft wie sau

Habe das Set mit dem Tuningnadellager und dem Vergasertuningset verbaut. Alles läuft und harmoniert super. Schwalbe fliegt dahin ohne jegliche Probleme und enormer Leistungssteigerung, was man bei so ner alten 3-Gang Schwalbe echt merkt...
