Incl. 20% VAT.

Full-flange crankshaft for Puch E50 engines, which are installed in Puch Maxi S / N mopeds / mopeds.

The crankshaft with original 43 mm stroke is made of forged steel, which makes it tougher 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.
