Not so nice 
Crankshaft compatible with Puch X30 Sport NS / NL mopeds (not suitable for Velux engines).
So-so! – We strive to offer you the widest selection of moped replacement parts. However, the quality of this product is rather so-so, and we do not recommend it. If you still decide to go with this item, we understand your choice, but we cannot offer any warranty or exchange.
The connecting rod bearing may be too rough, which can cause the lubricating film to break down. This, in turn, can cause the connecting rod bearing to overheat.
You can find high-quality alternatives, such as our swiing crankshaft or bearings and oil seals, in the accessories section.
A brand-name product from the Portuguese manufacturer Jasil under the Top Racing brand.
