BGM PRO crankshaft for Vespa Wideframe models made of high alloy forged blanks. Ideally suited in combination with the BGM PRO 150cc Wideframe tuning cylinder.
The crankshaft is designed as a heavy duty tuning crankshaft, but is of course also as a virtually indestructible shaft for original engines a clear recommendation.
Pipe length: 110mm
Piston pin: Ø15mm
Pipe bearing: Needle roller bearings (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 roller bearing (instead of a plain bearing bush) as well as a slotted lower connecting rod eye. The oil requirement is thus significantly reduced so that the engines with today's high-quality oils can also be driven with 1:50 mixture without problems.
The balancing factor has been improved, among other things, by a hollow drilled crankpin.
The crankshaft is suitable for all 125ccm and 150ccm engines. The 125ccm engines only have a stroke of 54mm ex works, therefore a cylinder designed for 57mm stroke is required (BGM1550, Pinasco Nordkap).
The BGM PRO Wideframe crankshaft fits the following vehicles:
Vespa: VM, VN
ACMA: 125 (70191 - 295883), GL150
Motovespa 125N, 125S, V56, V58, V72
Douglas GL2, 42L2, 92L2
