Description
Racing crankshaft 60cc - 70cc
Our new racing crankshafts in solid cheek design are currently the best crankshafts for your Simson engine. In the completely newly manufactured crankshaft, we were able to realize many design advantages over a subsequently rebuilt Simson crankshaft. Due to the 1 mm wider crank cheeks in each case, the basis for optimal balancing and higher rigidity (stronger press fit) is laid. With the help of the pressed-in aluminum plugs and the lighter connecting rod, the balancing is adapted to our S60 and S70 pistons. This results in a low vibration engine run, increased rotation and longer bearing life. For the bottom guided bearing we use a high quality silver plated needle bearing (13 mm wide) with silver plated thrust washers. This eliminates the need for the upper thrust washers in the piston and provides space for a 16 mm wide needle bearing.
Technical data:
- ZT racing crankshaft with 44 mm stroke
- 16mm needle bearing for piston pin
- Woodruff key for ignition + clutch

- wide upper needle bearing (16 mm)
- balancing optimal for S60 + S70 pistons
- reduction of crankcase dead space
- ZT racing crankshaft with 44 mm stroke
- 16mm needle bearing for piston pin
- Woodruff key for ignition + clutch
