Exact reproduction of the original crankshaft as used in the first Vespa engines with rotary valve control (VBA1T, VBB1T, VBB2T, VNB1-6T, Tour/T4 (VGLA, VGLB), VLA1T).
Has a needle bearing mounted connecting rod and thus replaces shafts with connecting rod bushings (e.g. VNB models). Can therefore be run without problems with an oil ratio of 2% (1:50).
High quality version from Tameni, Italy.
