Details

BGM PRO crankshaft for the Spanish Motovespa models 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
Connecting rod length: 110mm
Piston pin: Ã15mm
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 bushing) as well as a slotted lower connecting rod eye. The oil requirement is hereby significantly reduced so that the engines with today`s high quality oils can be run without problems with 1:50 mixture.

The balance factor has been improved by a hollow-bored crank pin and is based on the original Tarabusi piston of the Spanish engines.

The crankshaft is suitable for all 125cc and 150cc Motovespa Largeframe and Vespa VNA engines. The 125cc engines have a factory stroke of only 54mm, so here you need a cylinder that is designed for 57mm stroke.

The BGM PRO crankshaft fits the following vehicles:

Vespa: VNA1T - VNA2T
Motovespa 125
Motovespa 125N, (M61, M64, 542M, V101M)
Motovespa 125L, (M62)
Motovespa 125S, (V60MS)
Motovespa 150F (V203M)
Motovespa 150L (V202M)
Motovespa 150S (V201M)
Motovespa 150S (502M)
