Product Information "Racing crankshaft 85ccm-105ccm, 95mm connecting rod - for Simson S70, SR80, S83"
Racing Crankshaft 85ccm - 105ccm
Our new racing crankshafts in full counterweight 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 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 allows the upper thrust washers in the piston to be omitted and a 16 mm wide needle bearing to be accommodated.
Technical data: - Connecting rod length 95mm - wider crank webs (each web +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 optimal for our S85 pistons - Reduction of the crankcase dead space
Scope of delivery: - ZT Racing crankshaft with 44 mm stroke - 16mm needle bearing for piston pin - Disc spring for ignition + clutch
