Description
Sportfreund crankshaft from Schmitt with 44mm stroke and 85mm connecting rod suitable for Simson moped / mokick S51, S53, S70, S83, SR50, SR80, KR51/2 with M531, M541, M741 engine.
Here the standard is redefined! A manufactory made, balanced & precision machined crankshaft with 44mm stroke and 85mm connecting rod designed for stock to mid range tuning engines. The reinforced press fit between the crank pin and the stroke disc makes the Schmitt crankshaft significantly stiffer and more speed resistant. The Schmitt crankshaft with reinforced connecting rods and silver-plated needle bearings is noticeably smoother and easier to turn. The connecting rod is guided by the lower connecting rod bearing with silver-plated thrust washers, eliminating the need for fiddly shims on the piston pin.
With this crankshaft, special attention is paid to the accuracy of fit from the ignition cone in the original ratio of 1:5. This means that inaccuracies are no longer an issue when mounting modern flywheel masses. Concentricity deviation and bearing seat fit also meet the most modern measurement and manufacturing standards and are not comparable with crankshafts from mass production or Asian manufacturing.
