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 Yamaha con rod with 110 mm length gives an easier life to the big end bearing. The delivery of every crankshaft contains a 3 mm base spacer to equal the longer rod. 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. The combination with the right undersize to the crank webs and a special adhesive as a fluid is perfectly suited against twisting.
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.
