Made from high alloy forged blanks. The crankshaft is designed as a heavy-duty tuning crankshaft, but is of course also a clear recommendation as a virtually indestructible shaft for original engines.
Stroke: 57mm (also available as tuning version with 60mm stroke)
connecting rod length: 105mm
Piston pin: Ø15mm
Connecting rod bearing: needle bearing (silver cage top and bottom)
A big advantage of the BGM PRO crankshaft compared to an original one is the use of a high quality connecting rod with needle bearing (instead of a plain bearing bushing) as well as a slotted lower connecting rod eye. The oil requirement is hereby significantly reduced so that the engines can be driven with today's high quality oils without problems even with 1:50 mixture.
The BGM PRO GS150 crankshaft fits the following vehicles:
Vespa: GS150 (all models: VS1-5T)
Motovespa 150GS (engine 04M), 150S (VTT, V13502C), 150 Sprint (engine 04M)
