Description
BGM PRO crankshaft for Vespa Wideframe models made from high-alloy forging 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 a clear recommendation as a virtually indestructible shaft for original engines.
- stroke: 57mm
- connecting rod length: 110mm
- piston pin: Ø15mm
- connecting rod bearing: Needle bearing (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 bush) as well as a slotted lower connecting rod eye. The oil consumption is reduced so that the engines with today’s high-quality oils can be run with 1:50 mixture without problems.
The balancing factor was improved by a hollow drilled pin.
The crankshaft is suitable for all 125ccm and 150ccm engines. The 125cc engines have a stroke of 54mm ex works, therefore a cylinder with a 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
