The GS160/SS180 has been designed much more robust and complex with a large needle bearing cage mounted on the outside of the kick starter pinion tread. Thus the circulation speed is clearly reduced as well as the bearing surface is considerably larger than in Rally and Co.
The bearing consists of several individual parts and was not available for a long time.
We now offer the individual needle bearing in addition to a completely newly reproduced bearing made in Germany.
