Full-flange crankshaft for Puch E50 engines, which are installed in Puch Maxi S / N mopeds / mopeds.
The crankshaft is made of forged steel, which makes it stronger and more resilient than conventional standard crankshafts.
For perfect balancing and pre-compression of the crankshaft, the balancing bores are sealed with tungsten plugs.
The connecting rod eye has a diameter of 17 mm. This means that different needle bearings can be used if a 12, 13 or 14 mm piston pin is used.
The racing crankshaft has a stroke of 44 mm. This is 1 mm more than original. A 0.5 mm spacer should be used.
