Piaggio Vespa GP Bravo 125ccm 

@@mistral22 Hello, I think that the Kugel Velle was already damaged because I bought it second-hand. Or the manufacturer sold a poor quality product.

​@@vrt37you had an interference fit with the bearing before?

The ball bearing was stuck at first and then came loose on the shaft. I will now order a new crankshaft.

@@vrt37 thank you for the replies, i love your work on these mopeds ;)

@@mistral22 No problem and thanks for the kind words. There will be another video soon. I'm currently converting the engine from 125cc to the 172cc Malsossi because the 125cc cylinder has too little power. With the 55mm stroke shaft, the engine will then have approx. 182cc 😊👍🏼
