Crankshaft -MAZZUCCHELLI Standard (rotary valve)- Vespa V50, PK50 S (Ø=19mm cone)
Part no.:
1610001
Description
The standard crankshafts for the V50 are very well suited to replace the old original shafts, with bushings instead of needle bearings in the upper connecting rod eye. This brings a strongly increased life span of the engine with itself, since the connecting rod bushings become frequently unround, and/or deflect with the time.

TIP:
For cylinders starting from 75cc capacity directly a broader upper connecting rod bearing also order! (see "Accessories")
