Solid-flange crankshaft with polished connecting rod, compatible with various mopeds equipped with Puch E50 engines.
Additional lubrication slots on the connecting rod and the lower connecting rod bearing, in combination with the built-in silver cage and bronze thrust washers, ensure low-friction operation even at high RPMs. The balancing holes in the side plates have been sealed with aluminum inserts to achieve maximum pre-compression.
The needle bearing is included in the package.
You can find compatible bearing sets for the “old model” in the accessories section.
