Racing Crankshaft 60ccm - 70ccm


Our new racing crankshafts in full web construction are currently the best crankshafts for your Simson engine. In the completely newly manufactured crankshaft, we were able to realize many constructive advantages over a subsequently modified Simson crankshaft. The 1 mm wider crank webs lay the foundation for optimal balancing and higher rigidity (stronger press fit). With the help of the pressed 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 revving ability, and longer bearing life. For the lower bearing, we rely on a high-quality, silver-plated needle bearing (13 mm wide) with silver-plated thrust washers. This eliminates the need for upper thrust washers in the piston, and a 16 mm wide needle bearing fits in place.

Technical data:
- Connecting rod length 95mm
- wider crank webs (each web +1 mm)
- wider and stronger press fit of the crankpin
- lower guided, lightened connecting rod with additional lubrication grooves
- wide, silver-plated needle bearing (13 mm) + silver-plated thrust washers on the crankpin
- wide upper needle bearing (16 mm)
- balancing optimal for our S60 + S70 pistons (also available for other pistons on request)
- reduction of crankcase dead space

Scope of delivery:
- ZT Racing crankshaft with 44 mm stroke
- 16 mm needle bearing for piston pin
