BGM LAMBRETTA  RACE CRANKSHAFT ---

Forged high primary compression crankshaft with Yamaha con rod.
The balancing was highly focused while the development took place. Thanks to the balancing weights combining Tungsten (100 gr. each side), copper weights and hidden pockets the crankshaft gives a very smooth engine run.

 The lubrication of the big end is by two sufficient slots. The open cage silver bearing leaves nothing to be desired. The diameter of the gudgeon pin is 22 mm.

Upshot: All in all the bgm crankshaft gives the highest possible quality to every single component. Production accuracy, forging technology as well as the highly elaborated balancing leaves nothing to be desired.
