Racing Crankshaft Long Stroke 48 mm
With our new long-stroke crankshaft, we are expanding our product range for Simson with another highlight. In the completely newly manufactured crankshaft, we were able to realize many constructive advantages over a retrofitted Simson crankshaft. The 1 mm wider crank cheeks lay the foundation for optimal balancing and higher rigidity (stronger press fit). With the help of the pressed-in aluminum plugs and the lighter connecting rod, the balancing is precisely adapted to our S85 piston. This results in a low-vibration engine run, increased rev-happiness, 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 finds its place.
Technical data:
- Connecting rod length 85mm
- wider crank cheeks (each cheek +1 mm)
- wider and stronger press fit of the crank pin
- lower guided, lightened connecting rod with additional lubrication grooves
- wide, silver-plated needle bearing (13 mm) + silver-plated thrust washers on the crank pin
- wide upper needle bearing (16 mm)
- balancing optimized for our S85 piston
- reduction of crankcase dead space
Scope of delivery:
- ZT Racing Crankshaft Long Stroke 48 mm
- 16 mm needle bearing for piston pin
- Disc spring for ignition + clutch
