Product information "Schmitt Crankshaft "Sportfreund" - for Simson S51, S53, S83, KR51/2 Swallow, SR50, SR80"

Schmitt Crankshaft "Sportfreund"


- newly defined standard
- manufactured in a manufactory process, balanced & precisely made
- crankshaft with 44mm stroke and 85mm connecting rod
- designed for standard to medium tuning engines
- reinforced press fit between crank pin and hub disc
- significantly stiffer and more resistant to speed
- noticeably smoother and more eager to rev
- reinforced, bottom-guided connecting rod
- silver-plated needle bearing and thrust washers

Technical data:
- Balancing factor: 64% with Ø38mm piston, 59% with Ø41mm piston, 52% with Ø45mm piston
- Weight: 1380g
- Connecting rod: 85mm
- Stroke: 44mm

Note:
The installation of fiddly thrust washers on the piston pin is no longer necessary.
This crankshaft pays special attention to the accuracy of the ignition cone in the original ratio of 1:5. This means that inaccuracies in the installation of modern flywheels are no longer an issue. Runout deviation and bearing fit correspond to the latest measurement and manufacturing standards and are not comparable to crankshafts from mass production.

Schmitt enttäuscht nie

Ich habe diese Kurbelwelle in meinem Sr50, weil die Originale kaputt war. Läuft ohne Probleme.
